Extreme Overclocker Bargain
Pros: Great looking motherboard Orange LEDs on board are nice touch. System Status App is pretty sweet. I checked some of the temperature readings with my laser thermometer and they were spot on. BIOS has a search function, which is useful when first learning your way around the BIOS. System Info Viewer app displays voltages that are identical on to what is measured when using the DMM probing points on the board. At first I thought the SIV was wrong because it was showing higher values for CPU VCORE than CPU-Z and HWInfo, but it turns out that CPU-Z and HWInfo only display the values set in the BIOS. SIV and my DMM confirmed that the motherboard applies .016V more than what is set in the BIOS for CPU core. Direct-to-BIOS button is very useful especially with lightning fast SSD boots. This is about as serious of a motherboard as anyone could want if you are going to do extreme overclocking and/or for running several GPUs. It has a myriad of features to please the extreme enthusiast that are normally only found on boards in a much, much higher price bracket. You will find numerous negative nit-pickings below because I tell it how it is. However, once a few small kinks are worked out in the BIOS, this board will shine as an extreme bargain in the extreme enthusiast market.
Cons: Using the +/- CPU Ratio/Frequency buttons on the board worked while in Windows, but kept causing lock-ups. I never have high expectations for included utilities so I wasn’t that surprised when things didn’t act as planned. These are cons, but only minor ones in my opinion as the target audience for this board probably won’t be relying on utilities to do anything. Easy Tune requires a reboot to alter settings, making it pretty useless IMO. Why not just OC from the BIOS in the first place? System Info Viewer was not displaying correct RAM speeds. It displays stock settings even when using XMP. APP Center driver update doesn’t work very well and is more or less worthless IMO. I always go to site and download latest drivers immediately but APP center said EVERYTHING was out of date after the fact, so I let it run. I was anticipating an automated process, which it is not; It opens up the Intel install windows behind the APP Center which at first I didn’t notice until I looked at task bar. Secondly, the download speeds through it are TERRIBLE @ <200KB/s. And lastly, it downloaded all of the same drivers I just installed; I was prompted to repair/remove instead of install/update the drivers. I removed APP Center after the utter failure of the driver update utility only to find that APP Center must be installed to use any of the other utilities associated with this board; Easy Tune, @BIOS, SIV, etc. @BIOS, the BIOS update utility, froze when trying to update from every server available. After the BIOS flash failed from the server option I received 2 errors in Windows after rebooting; “Open Device failure” and “Driver can’t release to failure”. These errors went away. Manually downloading the BIOS worked fine, but the computer must be restarted anyway so why update from Windows? Flashing from the @BIOS utility also took much longer than I was anticipating; it is simply a better idea to flash from the BIOS. Having the server BIOS flash from within the BIOS, like ASRock, would be a much better option. I expected better things from the BIOS considering how much the Z87 board I reviewed pleased me…however: When Trying to enter “Classic Setup Mode” the BIOS kept locking up. Motherboard has 6 System Fans, yet only 4 are displayed in the BIOS. Had issues with drop down menus leaving a ‘shadow’ of it elsewhere in the BIOS; exiting BIOS only way to fix it. When altering a setting from normal/auto in the BIOS, I could not figure out how to get back to normal/auto. Usually normal or auto is placed at the top/bottom of the drop down list, but it isn’t in the list at all. I needed to exit BIOS without saving to get these back to normal/auto. Setting the CPU to “Default OC” also disables XMP profile. Enabling the CPU “Light Overclock” applied settings, but the XMP profile did not apply with it for some reason.
Overall Review: Board wouldn’t POST; had to move RAM/reset CMOS several times Couldn’t install Windows from USB3; Z87X-UD5H didn't have this issue. Europe mirror maxes my internet @ 6.9MB/s; others were very slow. System Info Viewer displays higher CPU core temperatures than RealTemp & HWInfo. I’m not sure if it is giving a more accurate reading like it was for voltages Memory DIMM switches don’t work as you would imagine if you’re only using 2 DIMMs. Even if you have slots 3 & 4 filled, you still disable them by using switches 1 & 2 The Gigabyte site board/driver search function needs some fixing. I could not get this board to be displayed when searching for Z97X SOC Force, the results list would be blank. When I would search for Z97X SOC, it only showed regular SOC, not the Force. This caused me to accidentally download BIOS for the Z97X SOC board by mistake; which did not work. I recently did a review for the Gigabyte Z87X-UD5H and was expecting to be fairly familiar with the BIOS but things have been moved around and altered a bit; I prefer the Z87. I was also surprised given the enthusiast market this board is aimed at, to not find more settings. Unless I missed them, the one thing I was specifically looking for, and didn’t see, was Load Line Calibration for a few settings like on my Z87 Gryphon. With Haswell ‘K’ CPUs, the OC potential is likely more reliant on getting a good chip then the abilities/quality of the board; unless you are running dry ice or LN2 obviously. Anyone purchasing this board shouldn’t be relying on auto tuning settings, but I had to test it for the Z97 platform. The results weren’t any different than my experience with numerous Z77/Z87 boards unfortunately. I’m not listing this as a con because from my experience I have found ‘Auto Tuning’ and presets are unreliable and will likely apply unnecessary/dangerous voltages to CPU. For optimized default settings for 4770k @ stock it sets 1.232V with RAM @ 1333MHz; On average a decent 4670k/4770k will reach ~4.5GHz @ ~1.25V. After a couple hours of tweaking I found that only .016V additional was necessary for 4.4GHz overclock while using 2400MHz memory. Unfortunately the i7 4770k I purchased to review this board isn’t a great one. I got to 1.391V core to try and get 4.5GHz stable with no luck, as well as being out of cooling capacity at that voltage. I chose 4.4GHz with Auto Voltages just to see what would happen and it applied a destructive 1.477V, which locked up the computer immediately. The capabilities of this board are likely outside the scope of the average user. I wish I had more extreme cooling means to really test this board... ..I am strongly considering building an extreme test bench with this board at the heart of the operation for Devil's Canyon overclocking. Need more time to get an even better feel for this board; Have Devil's Canyon on pre-order :D Thanks NewEgg and Gigabyte for another review opportunity!
Good. Could be Great.
Pros: Plug and Play 5 year warranty USB A & C Cables Relatively compact Very short burst speeds seen exceeding 1 GB/s Aggressive pricing for 1TB model compared to other brands Good real world transfer speeds *** as long as your hardware supports it *** Reaches, and slightly exceeded, advertised transfer rates in ATTO & Crystal Disk Mark benchmarking tools. *** actual use transfer speeds are not this high though *** Corsair SSD ToolBox software is a small 5.3 MB download which allows you to check/update firmware & monitor temperature. Drive came with latest firmware UIFM00.3 installed
Cons: Advertised benchmark speeds dont translate to real world, actual use case, transfer speeds. Drive overheats and then throttles when writing large amounts of data. I found after ~6 minutes of consecutive writing to the drive that transfer speeds would suffer. It is important to note that when transferring FROM the Corsair to another drive, there were no throttling issues experienced. Temperatures seen in Corsairs SSD Toolbox software were frequently in the high 70s celsius and peaked at 80C/176F. I measured a peak of 52C/125F externally with an IR thermometer. Cap for the port is held on by a tiny, ~1/16 diameter & ⅛ long, piece of rubbery plastic. Theres also no indicator as to which side you should open it from. Use too much force and I can see it easily broken off. Corsair SSD ToolBox software seems a bit dated. You can view the drives temperature, but you must hit a refresh button to see current temp; Refreshing also takes 5-6 seconds. No other functions of SSD Toolbox are available for the external drive; over provisioning, disk clone, TRIM optimization and Secure Wipe. Can build an equal/better performing drive with a NVME enclosure. Drive not serviceable, outside of RMA, if there is an issue. No status/indicator light.
Overall Review: My PC Specs: ROG Strix Z690-G i7 13700K @ stock 32GB DDR5 6400-CL32 G.skill Trident Z5 RGB Boot - Samsung 970 Evo+ 2TB PCIe 3.0 Storage -Inland QN322 2TB PCIe 3.0 Storage - 6TB WD Black 3.5 HDD PowerColor Red Devil RX 6900 XT Seasonic Prime Titanium 750W I tested transferring to/from this drive via my internal PCIe drives with various file types to showcase real world performance. Its fun to see high numbers in benchmarks, but thats not where the performance actually matters. All tests were performed via a 20 Gb/s port except to demonstrate how a 10Gb/s port inhibits benchmark speeds. I pitted the Corsair against a 10Gb/s USB-C 3.2 NVME M.2 NVME external enclosure: Sabrent EC-SNVE SSD: 512GB SK Hynix BC711 HFM512GD3JX016N - PCIe 3.0 x4 (SSD pulled from a laptop I upgraded storage in. Nothing special just an OEM drive.) I used the following types of data to test the capabilities of the drive: Steam library - 9 games totalling 468 GB - 4,312 files in 648 folders. 2 Acronis disk images totalling 104GB Music files - 63.4 GB - 11,725 files in 753 folders. Video files - 59.1 GB in 53 files Backup of various image types from my iPhone 14. 1,595 files totaling 3.45 GB. PNG, JPEG, HEIC, & GIFs ranging from as small as 10KB to 12,141 KB with 433 of the files under 1 MB. Transfer to Corsair: Steam Library - ~22m 40s = ~370.7 MB/s Acronis Images - ~3m 30s = ~535.7 MB/s Photos - ~5.92s = ~553.5 MB/s Music - ~2m 37s = ~436.5 MB/s Video - ~1m 55s = ~552.2 MB/s Transfer to external NVME: Steam Library - ~12m 19s = 680.1 MB/s Acronis Images - ~2m 40s = 703.1 MB/s Photos - ~6.27s = 522.6 MB/s Music - ~1m 51s = 613.4 MB/s Video - ~1m 26s = 738.3 MB/s Comparative Results: Steam Library - Sabrent 89.7% faster Acronis Images - Sabrent 31.2% faster Photos - Sabrent 5.6% slower Music - Sabrent 40.5% faster Video - Sabrent 33.7% faster *_*_*_*_*_*_*_*_ Transfer FROM Corsair: Steam Library - ~9m 34s = ~875.6 MB/s Acronis Images - ~2m 1s = ~929.7 MB/s Photos - ~10.3s = ~318.1 MB/s Music - ~1m 33s = ~732.2 MB/s Video - ~1m 8s = ~934 MB/s Transfer FROM external NVME: Steam Library - ~8m 25s = ~995.2 MB/s Acronis Images - ~1m 46s = ~1,051.4 MB/s Photos - ~8.19s = ~400.1 MB/s Music - ~1m 22s = ~830.4 MB/s Videos - ~1m 1s = ~1,041.2 MB/s Comparative Results: Steam Library - Sabrent 13.6% faster Acronis Disk Images - Sabrent 13.1% faster Photos - Sabrent 25.8% faster Music - Sabrent 13.4% faster Video - Sabrent 11.5% faster *_*_*_*_*_*_*_*_ The Corsair was bested in every scenario aside from transferring photos to the drives, and this particular test had a fraction of a second separating them; a wash IMO. The performance delta is exacerbated if youre moving 100s of gigabytes of data onto the Corsair in one shot. Once the drive reaches maximum operating temperature, ~75-80C in ~6 minutes, it throttles and fluctuates between 3-400 MB/s. Redoing the Acronis transfer while the drive was hot enough to throttle experienced a 15% performance loss, increasing transfer time by 37 seconds and reducing transfer speed 80 MB/s. Conversely, to test thermal throttling theory, I placed the drive in a some sandwich baggies and then into ice water. I re-tested by copying the steam library to the Corsair. Theory validated! Peak temperature was 56C/133F instead of 80C/176F. Transfer completed in ~17m 40s averaging ~475.6 MB/s. That's 5 minutes quicker and netted a ~105 MB/s, or ~28.3%, boost in transfer speed. *_*_*_*_*_*_*_*_ The 20Gb/s capabilities of this drive unfortunately are only good for showing higher benchmark numbers as it is clearly bested by a drive with a slower connection capability when it really matters. You can see this in the ATTO/CDM benchmark photos posted. *_*_*_*_*_*_*_*_ The Sabrent enclosure can be had for $30 here at Newegg. You can pair it with a robust selection of 1TB M.2 NVME drives for $55, or less, to match/beat the $85 Corsair is asking; many of the NVME match the 5 year warranty. The enclosure itself only carries a 1 year warranty as standard; 2 years if registered. The Sabrent's advantages are an easy drive swap in case of a failure/upgrade, acts as a heatsink to prevent thermal throttling, and has an LED indicator light. The Corsair does have a smaller footprint. It is ~1.5in/38mm shorter, but ~3/16/5mm wider, while both share the same thickness. It also doesn't get any simpler than just plugging the drive in. *_*_*_*_*_*_*_*_ The Corsair drive was almost always outpaced when actually transferring. The tinkerer in me will go for the external enclosure every time since it provides better performance and features; most importantly the ability to swap the drive. However, the average user looking for instant plug-N-play functionality will likely still be blown away by the performance provided. Were talking about moving entire CD/DVD capacities in seconds...which is crazy and awesome! Get the thermal throttling under control and Corsair has another hit.
Can't comment on how good bulb is. Could not get bulb to connect to WiFi
Pros: I can't really think of too much. Registration was easy and straight forward for the Magic Home Pro application. However that is about it.
Cons: Could not get bulb to connect to my WiFi. Poor in app translations. It is obvious the text for the app and instructions have been machine translated.
Overall Review: I made several attempts over several days trying to get this smart bulb to connect to my wifi. I have a fairly advanced setup as far as home networking goes. I have separate networks for my smart devices and my regular computers and devices. I could not get the bulb to connect to either network. The poorly translated app suggested i disconnect my phone from cellular service, and that made no difference. After a half dozen attempts the app moved forward and it looked like the bulb would connect. That was wishful thinking. I just received another error saying the connection failed and that my WiFi password was incorrect. It was not incorrect. I checked and tried multiple times. I tried the setup from both an android device as well as an iOS device. Neither worked. I attempted to bring my network down to 2.4 Ghz only mode as the app suggested, and then it only timed out trying to add the device. I disabled my network Pihole as well as any additional mesh routing points. Nothing I did made a difference. I would love to give some feedback on the bulb however it will only cycle through a few dim white colors until setup is complete. I can't even use it as a regular bulb. I may try setting the bulb up again in the future. If I have more success I will change the rating accordingly. As of right now I can't give this bulb anything but a 1 egg review as it simply doesn't function without being able to add it to WiFi. Also the app implies the bulb can only work if their is no 5 Ghz network present is a deal breaker for me. I am not willing to shut off the better part of my WiFi network to accommodate a cheap product. And I only did this in a desperate attempt to get the bulb connected and see if I could obtain functionality.
ITX Workstation Dream Come True
Pros: Simple/clean aesthetic. Lifetime warranty*. * With all original packaging! Both XMP profiles functioned in my MSI Z790i/12600K ITX system; RAM not listed in QVL. The highest, and honestly insane, RAM density per DIMM currently available at 64GB...thus enabling professional workstation capabilities in the smallest ITX systems. Relatively low voltage @ 1.1V for 5600 MT/s; especially for this capacity. Helps ensure within spec operating temps even under severe extended load; more in overall review. Low-profile heatspreader means these should be compatible with any (tower) cooler even if you populate all 4 slots. Impressively thorough/useful installation instructions from the Crucial product page under installation/support.
Cons: Perhaps an overlooked requisite of extra large RAM capacity is extended boot times; especially true if RAM training is enabled for each boot. 56.7 & 55.5 second BIOS times as reported by Windows Task Manager. Quadrupling RAM capacity from 32 to 128 gigs essentially quadrupled my BIOS times from ~15 seconds; system specs in overall. Price? However, if youre looking for this capacity of RAM, it is likely for work more than play. Not the highest speed, or tightest timings, but that is a tradeoff with 64GB per DIMM. Crucial requires original packaging for a valid RMA! Make sure you toss RAM package, and/or anti-static bags, in your mainboard box! The following quoted from Crucial RMA process: vii. How the Return Process Works Ship the product in question to Micron CPG in its original packaging and enveloped in the original antistatic bags (product to be shipped at your expense).
Overall Review: Ultimately this product is targeted at professionals/workstation users where capacity is king and higher MT/s & lower timings/latency take a back seat. Under stock conditions the RAM performs admirably, even under the harshest conditions; i.e. 28 continuous hours of RAM stress testing. If you want to build an ultra compact ITX workstation with 128GB of RAM, look no further...Crucial has you covered. (Even though I have the RAM in my PC, it's still a bit mind-bottling. I remember when a 1GB hard drive was cutting-edge and $399.99...) If you are looking to tweak/OC these ultra-high density DIMMs, you should have experience in this regard alreadyand bring your A-game in terms of patience. The extra lengthy boot, and RAM training, times make the process very, very tedious. After ~6 hours of playing around, and getting nowhere, I am throwing in the towel, for the moment, on altering speeds/timings. RAM is typically a "set it and forget it" component for me, so using this kit to experiment with tweaking was a fool's errand for sure. I dont like the term future proof in the PC spacehowever, I believe I can consider this system's RAM future proof. At least until DDR6 is mainstream __________ HTPC/Plex Server Test System: SSUPD Meshlicious MSI Z790i Edge Wi-Fi 12600K - Thermalright AXP-X67 w/ Noctua Slim PowerColor RX 9070 Reaper 500GB 970 EVO+ / Inland 1TB Premium Toshiba NAS N300 6TB & 8TB Phanteks AMP 650W Win11 LTSC 24H2 __________ Full part# cp64g56c46u5.m16b1 28+ hours with 0 errors in Memtest Pro. It took 37 iterations of MemTest Pro to fill ~120GB of available RAM with only Word, HWinfo, Paint & Discord running. Each DIMM peaked at 5.250 watts and averaged ~4.8 watts over 28+ hours. After 28_ hours the average operating temps were 62.0C & 62.8C, with both DIMMs reporting a peak of 79.8C in HWInfo. This is with very little, to zero, active airflow over the RAM with a completely open case; see photos for my system.

When switching between XMP profiles, it may be beneficial to reset to default first. Switching between 1 & 2 I initially received a motherboard/BIOS error for failed OC settings. Booted to 5800 @ XMP1. 63.8 sec BIOS time. 2ND boot at 25.5 seconds, ?strange?, but didnt want to enter UEFI or reboot without using power button after this.

PC did not want to enter UEFI from CMD prompt shortcut or trying to SHIFT-restart windows to enter troubleshooting mode. Ultimately had to clear CMOS and start over. Curiously, XMP1 would not function initially after this. Had to reset to defaults, apply XMP2, boot into windows, back to UEFI and apply XMP1now all seems to be well. BIOS time seems to have settled at 56.3 seconds according to Task Manager.
Solid drive from a solid manufacturer
Pros: - Fast - drive comes very close to reaching advertised speeds - Drive management software available (Crucial Storage Executive) - Storage Executive does not start with windows by default - Storage Executive now recognizes my drives from other manufacturers - 5 year warranty - Greatly reduced load times in my direct storage enabled games coming from a slower NVME drive. - Drive performs consistently - Drive runs cool, slightly cooler than from another leading manufacturer
Cons: - Drive does not quite hit advertised read speeds, falls about 300 MB/s short - Drive management software is terrible, granted not quite as terrible as it used to be. Software still excruciatingly slow and buggy. Not much has changed since the last time I attempted to use the software
Overall Review: Overall, I would recommend this drive to others. Definitely do not purchase this drive if you plan on using any of the drive management software features. The drive is fast, and has held up to my expectations in that regard. Non scientific "benchmarks" I did on my own: - Transferring files over my 2.5 Gb LAN off an SSD onto the Crucial SSD maxed out the network connection and never saw a drop in transfer rate 283 MB/s the entire time. - Copying 8 GB of large files off the drive to another took 4.2 seconds. copying them back took 3.7 seconds. I believe the majority of this time was Windows initiating the file transfer. Unlike previous NVME drives from this manufacturer, a NVME driver is not provided, or seemingly needed. Did not find one available for download or any mention of one on the website. The drive runs cool, installed under the included motherboard heatsink the drive is installed on. Drive runs a touch cooler than another high performance drive from a different leading manufacturer. It really can't be understated how bad the Crucial Executive Storage software is. It is incredibly slow to load when launching. (Still about 18 seconds) Moving between different tabs in the software is also painfully slow. No modern software should take this long to load on solid state storage. I did attempt to check for a firmware update for the drive through Executive Storage, but it error-ed out every time I tried. The software also didn't recognize what firmware was on the Crucial drive, while it recognized firmware on the other 5 drives from different manufacturers in the PC. After my previous experience, and the software failing the first task I gave to it, I did not bother with further testing. It is abundantly clear that Storage Executive software is an afterthought at best. Though to be fair it has made at least one improvement, in that all of my drives are now detected by the software no matter what manufacturer they are from. To sum everything up. If you are looking for a fast and consistent solid state drive, this is a good purchase. Do not purchase this drive if you are looking to be able to manage it with the included software. I give the drive 4 eggs. Would have been 5 if the drive has been able to reach advertised speeds. I am not dinging the drive for the poor management software, as the drive is perfectly usable without it.
Chonky Cables & Coil Whine (RM850x 2021 version)
Pros: 10 year warranty Neutral colors fit any build theme Can connect 14 SATA powered devices Finally ditched the floppy drive adapter cable Large triangular mesh design matches that of new Corsair cases 0-RPM fan mode under moderate load means it will be 100% silent. Essentially inaudible operation even with a 500+ watt load on the unit. Cybenetics independent testing has confirmed the claimed 80+ Gold efficiency. No excessively wasteful or extravagant packaging; potentially a con given the price. Corsair branding/logo and RM850x will be right-side-up regardless of orientation of the PSU
Cons: Indefinite, and very strange, coil whine from my RX 6900 XT while using this PSU. See attached video and make sure to turn your volume all the way up. You can hear coil whine change when I use my mouse's scroll wheel and hit/hold down a key on my keyboard. Caused my 6900XT to overheat quickly. (more in overall review) No Corsair badge or bag for extra cables. User manual or quick start guide not included; must download. Online user manual list of included cables do not match what is actually included/what is on the product page(s). (more in overall review) Not capable of enabling/disabling 0-RPM fan mode like other manufacturers. Thick cables with horrendously stiff heat shrink too close to connectors make cable management much more difficult than necessary. You have less than 1" of flexible wire from the CPU/GPU connectors. Cumbersome 6+2-pin daisy-chain PCIe cables look terrible compared to competition. (see photos) Only (2) 6+2-pin PCIe daisy-chain cables included. (3) ATX/CPU 8-pin cables included; no motherboard I can find uses 3. 160mm depth is fairly standard these days, but not necessarily compact compared to 130mm & 140mm offerings from other manufacturers; Potentially a deal breaker for the ever increasing in popularity SFF PC build scene.
Overall Review: I'm fairly confident I received a faulty unit based on how my GPU acted while using this PSU. If not, then the daisy-chain PSU cables could be contributing to the problem. The possibility that I've received a faulty unit aside, I would not recommend due to poor value and the combination of cables included. The online manual states you'll be receiving (2) ATX/CPU 8-pin cables and (3) 6+2-pin PCIe cables. Corsair has changed this to (3) ATX and (2) PCIe daisy-chain cables. While this information is correctly listed on the product page, and packaging, it is still a problem. There's no motherboard I can currently find for sale, even the $1,000 ASUS ROG Crosshair X670E Extreme, that have triple ATX power plugs; making the 3rd unnecessary e-waste. Going from (3) separate 8-pin PCIe cables to only (2) daisy-chain 6+2 cables could present problems pending your GPU configuration. I reached out to Corsair tech support regarding the daisy-chain cables and supplying up to 600W while using an ATX 3.0 adapter, and this is the response I received: "Being rated for 150 watts does not necessarily mean being capped at 150 watts. Our 12v power adapter cables are manufactured with hefty cables allowing them to safely handle more throughput, enabling them to handle 600 watts with only 2 PCIe connectors." Corsair is stating it is safe, but from what I have experienced personally, and read numerous times on various forums/sites, GPUs are best off being connected to individual cables per power connector to ensure proper functionality. This is especially true for power hungry GPUs like RTX 3080, and above, as well as AMD Radeon RX 6900/6950 XT. These cards can/will have large power draw spikes. Utilizing daisy-chain cables is well documented at this point to be a cause of instability. Corsair is obviously readying PSU's for RTX 4090's that will include 12-pin 12VHPWR adapters that use (3 or 4) 8-pin PCIe cables to supply 450W-600W. Corsair says this is OK. I don't have a GPU that requires one of these adpaters to test with, so I can only go off of my experience with my 6900 XT; which was not optimal. While I was able to stress the PSU with ~500W load from my 5900X, ~170W, and PowerColor Red Devil RX 6900 XT, ~330W, without any stability issues, I did have problems; none of which occur with my existing PSU. Constant, albeit, faint coil whine was present as soon as the PC powered up; even at idle More strangely was how the coil whine would change pitch by input from my mouse/keyboard. While typing the noise was most noticeable when holding a key down. Click/drag a window would cause it to change. The most noticeable, and annoying, was scrolling up/down a webpage with the scroll wheel on my mouse. I have attached a video of this issue. Comparatively, with my existing PSU, I would only encounter coil whine while at FPS generally in excess of 150; like loading screens or synthetic benchmarks. The other issue I experienced was overheating of my GPU. Running my 6900 XT to the brink, with OC BIOS enabled and +15% power limit, pushed the GPU hotspot temp to a blistering 107C in <2 min, and then stayed pegged/throttling at 105C. After reconnecting my PSU, it became clear that the speed in which the GPU hit, and maintained, those temps was due to the PSU. Over 15 min with the existing unit, the Hotspot slowly crept from 90 and eventually held 101C. The GPU PPT wattage (total gpu package power) topped at 314W out of the 324W available. With the Corsair it pegged at 323W and peaked 330W. I was viewing power draw in MSI Kombustor/HWInfo64. Whatever the Corsair PSU was doing caused the higher temps/power draw which netted ~100 MHz lower clock speed in MSI Kombustor. Something strange is happening with power delivery to the GPU. I don't know if there is a problem with the unit I received, or if the daisy-chain cables are contributing to the issues I am experiencing. Considering the unnecessarily thick/stiff cables, daisy-chain PCIe cables, extra CPU cable, coil whine and the peculiar behavior when stressing my GPU...I will say this PSU is a bit of a disappointment compared to my past experiences with Corsair. Newegg sent me a RM1000x ~6 years ago to review. While I had similar complaints regarding stiff cables then, the PSU performed flawlessly even with a larger load on it; a pair of overclocked R9 290's and a 4770k.
Incorrect items
Originally sent a SO-DIMM for a laptop when ordered a desktop RAM module. Received a fairly timely response to rectify considering the 4th of July holiday weekend. Messaged seller via newegg on 7/2/22 and received a response with a return shipping label and new tracking number on 7/6/22. 2nd item shipped by snail mail again despite the error. My original order was placed on 6/26/22 and I received the 2nd item on 7/11/22. 2nd RAM module received was still not what was listed/ordered. Granted it was a compatible stick of DDR4, however, the entire premise of searching out and ordering a very specific Micron RAM module is to get said very specific Micron RAM module to match what came in the Dell pre-built I was working on. One digit/letter in the model/part number for the RAM module is all it take for things to be wrong. Seller needs to work on attention to detail and verifying items before shipping.
Solid PSU with Solid Customer Service
Shipped promptly and arrived as scheduled for a ridiculously good price. $45 for a 700W gold rated PSU is stellar..even if it's not modular.
