Pros: 80 Plus Gold Efficiency
Fully modular so if you don’t need the cable(s), leave them out of your case
Includes a floppy power cable but as an adapter instead of being hard wired
Great long term support with a 7-year warranty
Supports the latest ATX12V v2.4 standard
Dead silent, even with over 400 watts of load, the fan never came on
Premium feel to the packaging in the box, even has a bag dedicated to holding your unused cables
Includes a bunch of SATA and Molex power cables that aren’t sleeved, they are flat, which gives them better play and bendability when stuffing them behind your case.
The 24 Pin, 8 Pin CPU power and PCIE power cables are sleeved very well and show no signs of coming undone or fraying like other low quality sleeved cables.
Cable length for the 24 pin is plenty long enough to reach most Mid Tower cases even with it running through cable management holes.
Tested this power supply against a 500 watt Supermicro 80 Plus Bronze using 3DMark Cloud Gate to stress the system as much as possible given my hardware as shown below:
• Off – Corsair RM 0.3 Watts
• Off – Supermicro 1.0 Watts
• Idle – Corsair RM 139 Watts
• Idle – Supermicro 146 Watts
• Load – Corsair RM 412 Watts
• Load – Supermicro 425 Watts
Power Supply Results from a PSU tester (Decent as all are within +/- 3%):
• 24 Pin +12 volt @ 11.8 volts = 98.3%
• 24 Pin -12 volt @ 12.1 volts = 100.8%
• 4 Pin +12 volt @ 11.9 volts = 99.2%
• +5v @ 5.01 volts = 100.2%
• +3.3v @ 3.2 volts = 96.9%
• Molex +5 volt @ 4.91 volts = 98.2%
• Molex +12 volt @ 11.9 volts = 99.2%
• SATA +5 volt @ 4.91 volts = 98.2%
• SATA +12 volt @ 11.9 volts = 99.2%
• SATA +3.3 volt @ 3.2 volts = 96.9%
• PCIE +12 volt @ 11.9 volts = 99.2%
Cons: The modular connectors to the 24 pin power cable that connects to the power supply are not the same type of connectors as my Corsair AX760i. Very disappointed that despite having two modular Corsair power supplies, I would have to swap out cables to use the new one. What’s the point of a modular power supply if a manufacturer can’t even standardize their own modular connectors?
The 8 Pin CPU power cable could be a little too short in some taller cases as it may not reach using the cable management holes on said cases.
Overall Review: Overall this power supply with its superb efficiency and premium feel is definitely a worthwhile buy. Other than some very minor complaints that won’t affect very many people, there really aren’t any reasons not to buy this power supply if it fits your power needs.
CPU: Intel i7 980X
GPU: Two Nvidia GeForce GTS 250s in SLI
PSU: Supermicro 500 Watt 80 Plus Bronze (PWS-502-PQ)
Pros: Fully modular power supply; you can even disconnect the ATX motherboard power connector (though I don't know why you'd want to as you wouldn't be able to start the power supply). Lots of plugs for everything; includes plenty of SATA and old school 4-pin drive plugs, along with two floppy connectors! The cables are flat rather than round which might be a ding for some, but look stylish in black.
No fan noise unless you're doing gaming. For regular PC work, the fan doesn't even spin! (There's a sticker pointing out that the fan not spinning is normal!) Once you fire up a game and your graphics card's draw really fires up the fan needs to spin to cool it, but by that time your graphics card's fans completely drown out the power supply's fan. So you effectively have a completely silent power supply, even though it's literally not true.
Packaging is a bit over the top... who needs a velvety bag for a power supply? Are people taking their power supplies out for nights on the town? Maybe I'm old school but I take a power supply, I attach it with screws, and until it dies I never look at it again.
80 Plus Gold certified, so if you buy a larger power supply than you need (which is what most people do) you're at least not thowing money away hand over fist with an inefficient power supply. So no matter how much load you demand (...or more importantly, DON'T demand) you're going to be at least 87% efficient. Nice! Granted it's not platinum or titanium, but those levels cost substantially more while only getting to 89% or 90% efficiency, respectively.
I don't know what it is about this design, but it seems as though it's more sleek than a regular power supply. I actually held it up to the power supply I removed that I was previously using, and it's the same size, it just somehow feels more sleek.
2x dual pci-e connectors for graphics cards. So you can run some monster rigs with this one.
Cons: Not 80 plus titanium. Not a real con, as that's kind of a ridiculous standard for most people.
Overall Review: If this power supply was stolen from me, and my previous power supply was broken, I'd likely buy this one as the replacement. Silent operation is very VERY nice, and it's only when you don't have it that you realize how much noise ruins experiences. I have absolutely no reason to swap this power supply out now that I've reviewed it -- it's just that good!
Pros: - This PSU is fully modular and has enough cables to connect dual GPU cards. Many PSU's out there claim to be modular but then the 24 Pin power cable and 8-pin CPU cable are connected.
- Single 62.5 Amp 12 V rail, I that is plenty of power to feed your overclocked Skylake CPU with a beefy Nvidia GTX 980Ti and a few hard drives. I actually [refer the stability of a single rail compare to PSU's that have multiple power rails, you get more stability and reliability on power delivery from my experience
- 135 mm thermally controlled fan, what this means is the fan turns on when needed and the speed is regulated according to how hot the unit gets.
- Comes rated 80 PLUS Gold efficiency, delivering 90% energy efficiency as per PSU rating, only the Platinum rating beats this.
- Pricing is very reasonable in my opinion, for the price you cant go wrong choosing the quality you get with this PSU.
- As expected from a Gold plus PSU you get 100% Japanese 105 C rated capacitors than ensure you get a very stable and consistent power feed with accompanying reliability.
- An impressive warranty, yes seven years and I can attest to Corsair's no hassle warranty, the stand firmly behind their products.
- In addition to the PSU and cables you get a storage bag to store the extra leftover cables as well as a few cable ties to tie the power cables behind your case motherboard plate or HDD frame.
Cons: - I have a full tower case and the PSU siths at the bottom, thus the 8-pin CPU power connector sits way up there. The cable that came with this PSU is too short, I had to use an extension piece to get it connected. i have to say that very few PSU's come with longer 8-pin cables so Corsair is not an exception.
- There is no way to test if the fan is working or not other than to wait for it to come above 300W load, so if the fan fails you would not know it... I would prefer that the fan spins very slow even at low load, that way you know it is working, something to think about.
- Other than this I could not find anything worth mentioning in this review that put me off.
Overall Review: - PSU came we packaged in the retail box, inside is the PSU came the following :
Corsair ATX Power Supply
AC power cord
DC Modular cable set
DC Modular cable storage bag
Corsair case badge
My PC has the following spec: Intel 5820k hex core CPU OC'd to 4.5 Ghz with a GTX 970, 480 GB SSD , a couple of terabyte drives, all on a Asrock X99X Killer motherboard. CPU watercooled with a Corsair H100i CPU cooler
This PSU was more than enough to power my setup, you can even put in a GTX980 Ti or Titan and there will be plenty of juice left. I ran my system for about 10 hours over a couple of days gaming and the system was rock solid
Pros: Chances are if you are looking at this product either you know Corsair makes quality products, or you have been recommended one of these power supplies. Here are the reasons why:
• Full 750w of power on the 12v Rail
• Semi-passive operation enabled by high efficiency
• 100% Japanese caps
• Plenty of connectivity cables (including SATA)
• Fully Modular
• Included cable ties for neat routing
• High reliability
• 7 Year warranty, which is fantastic
• 80+ Gold efficiency, and easily hits that, in some loads this unit can hit 92% efficiency @ 230v, (91% @ 115v)
• Unit is capable of outputting over 800w at decreased efficiency levels
Cons: This unit unlike its bigger brother the RMi model, uses a cheaper fan (Rifle bearing, vs FDB). The RMi model has a fan test button and it has the ability to connect to Windows to monitor the power supply.
Only has 1 EPS (4+4) pin connector, high end power supplies should include 2x 4+4 pin, or 1x 4+4 pin and 1x 8 pin as some high end boards have dual EPS connectors.
This unit is larger than my Season X-850 despite a lower power output (This unit had a depth of 7.09”)
Overall Review: Not all cables are flat, only the SATA, and Molex cables are flat.
The fan will turn on around the 400w range.
Do not plan on using this unit for SLi with anything above a 970 series, would recommend a 850w+ unit for those.
The RMx Series is replacing the older RM series.
If you choose to purchase this keep an eye on the RMi model as well, if the prices are rather close there is no reason why not to opt for the RMi.
Many people do not understand the important of a good power supply, your power supply powers your entire system, sure a high end power supply will not make it run faster, but you WAY less likely to blow out some of your expensive components, experience unexpected shutdowns, and burn down your house. A good power supply can last you a few builds, and it worth a good investment.
Speaking from experience, saving on a power supply made me spend another $150 for a new motherboard 10 years ago.
Pros: For my application in a recording studio DAW, this power supply is a prayer answered – absolutely silent! Paired with my similarly "fanless" CPU cooler and some SSDs, I have a rig that can sit right in the recording room – so much easier than running cables into another room. I haven't heard the fan come on yet, and with my relatively low wattage system, probably never will. I'll just cut a big hole in the top of my case (RF screened, of course) and let it cool by convection.
I appreciated the modular cable system – will certainly help airflow, compared to the usual mass of unused cables.
And I love the efficiency! When you read about how much of the world's electrical production is consumed by computers, it's clear that this is somewhere we can really "think globally, act locally." A product like this shows that you can have it both ways – power and efficiency. And with the seven-year warranty, electricity savings over the life of the product will be significant, and justifies a higher initial price.
Overall Review: Packaging is impressive, for sure, but maybe they could offer an "OEM” package for people who don't need the velvet bag, cable pouch, etc.
Pros: It works, and handled stress testing without issue. Has nice packaging too.
Cons: Fan is controlled automatically and you have to take Corsair's word that it'll turn on when needed (so if the fan happens to not function at all for some reason and it's needed, too bad).
Overall Review: My desktop has a FX-8350 running at 4.5GHz @ 1.48V, and a Radeon HD 7850. Stress-testing both at the same time resulted in no issues, and didn't even cause the fan on the PSU to turn on.
The PSU is also heavier than expected. It's built pretty well. The packaging is also really nice.
I kind of wish there was a way to manually control the fan. I wouldn't mind it operating at the lowest speed; that way, air would still flow over components and even help contribute to moving air outside the case. But if the PSU isn't being stressed hard enough, the fan is off. And considering the stress test I did wasn't enough, it seems like the fan will never run on my current setup.
Pros: Starting out, you can tell this is not your run-of-the-mill value power supply you buy for your dad’s computer because he surfs the net and that’s about it. Opening the box, there’s the bag containing your cables, and the bag containing the power supply. It feels more like unboxing a new toy than every other power supply I’ve had, were it’s mostly just a box to hold the thing. Once you take it out of the bag, you continue to see the quality of the build. The case is nice, with legible markings and words, that make it look nice. The fan guard is definitely much better than most. It also runs completely silently in my case. I mean that, I couldn’t get the fan to turn on at all (more on that later).
Build: The build quality and unboxing are the best I’ve ever had.
Fan: This PSU runs very cool without a fan running. I’ve got a GTX 770, and an i5 4670K, both of which I maxed out along with both of my HDD’s and after 20 minutes, the fan still wasn’t running. The case of the PSU was just barely warmer than room temperature (62 degrees F).
Cabling: This is a fully modular PSU, and that’s great. I prefer all the cables to be the wrapped circular ones, but this one has the drives as ribbon cables. That’s a purely cosmetic thing though, and I can see how some people would want them to be different. There are enough PCIe cables for two power sucking cards, and plenty of other power cords (SATA and the older molex type connectors. There’s even TWO floppy disk power connections… so it’s definitely backwards compatible).
Power: This is the big one. Clean power is very important for a stable system. While running both a CPU and GPU stress test, the output didn’t change at all, except for VCore dropped from .880V to .872V. That’s a very minor change, and did not affect stability of the system at all.
Cons: None. This is a great PSU and I’m very happy to have it.
Overall Review: Other thoughts: Installation into my case did not go without issue. My case (Coolermaster HAF922) puts the PSU at the bottom of the case. There are air holes in the bottom so you can mount the PSU either right side up (draws air from outside the case- although there’s not as much open space as I’d like) or upside down (draws air from inside the case). There are screw holes to fit both mounting styles. There’s also a set of rails to keep the PSU at the correct height, and they also have anti-vibration pads on them. The problem was that the fan guard extends past the edge of the PSU case, so right side up was not a possibility without removing the fan guard. Also, I had to screw the screws in outside the case, to widen the holes enough to mount it. I also had to remove the anit-vibration pads. However, since I can’t get the fan to turn on, those pads are not needed anyway. I would say these issues are more the cases fault, but if you do have a case that the PSU mounts on the bottom, your installation may not go perfectly smoothly.
Bottom Line: If I need another PSU, this is definitely at the top of my list to get.
Pros: I've been using Corsair supplies in my builds, almost exclusively now for the last 10 years. I can honestly say I have never had a Corsair power supply fail - and I have to believe that this one is no exception.
- It comes nicely packaged, with cable ties and a good variety of cables.
- The drive cables are ribbon-style, the power cables are not (they have integrated capacitors, for further supply voltage filtering)
- Unit will run in totally quiet mode, fanless up until around 325 watts of DC power load. Great for when you use your machine as a media server or general low-demand tasks.
- The build quality looks to be excellent. Even uses an epoxy-coated wire guard for the (huge!) fan - not cheap metal-stamped guard.
- Corsair did not cheap-out on key components; all capacitors are Japan-sourced and when I looked inside the case, appear to be way over-engineered for the job. You won't have any issues with failing caps (which often don't evidence themselves until damage has been done to your motherboard).
- 7 year warranty (!)
- Fully modular cables, easily used with dual graphics cards. Any cables you don't need - don't plug them in. No mess, no waste.
- Gold certified, meaning it is high efficiency and very stable across various line voltages, input spikes and/or noise on the supply side power. If you live or work in an area where you have sketchy incoming power, it's important to invest in a power supply rated this way.
- Unit is nice looking, and it has good heft to it. I know it sounds weird, but when devices like this feel heavy/solid -- it usually means they are well built (e.g. no skimping on transformers or heat sinks).
Cons: Hard to find anything wrong with this power supply. One odd thing, which is not a huge deal - it comes with 8 connectors for the old style "molex" 4-hole connectors (you know, the ones your dad used to use on floppy drives). Not sure why we need 8 of those. I would have probably went with an extra PCI-E cable instead, but it's not a big problem.
Overall Review: I am happy to have been given the opportunity to exercise this unit in my system for nearly two weeks, without a glitch. I run dual GPUs and was able to get the supply to run in fan mode. I also abused it a bit by blocking the intake air, and it didn't even get hot enough to shut itself down. It's a really well made unit and I would not hesitate to use it in my next build. At the price Newegg has it really is a no-brainer, unless you need to go with the 1000w unit which is even beefier!
