Corsair further improves the excellent RM line
Pros: The Corsair RM650x 2018 [V2] is the update to their RM line featuring 80+ gold level efficiency. It is produced by long term OEM partner channel well [CWT] It is fully modular, main cables are very solid construction wise and it features Corsair standard flat ribbon SATA cables which are stiff but can be made more pliable with hot air. The mild update includes a bypass relay which supports the NTC thermistor, allowing for increased efficiency and enhanced inrush current protection. Also included is a PIC micro-controller to control the fan's operation and allow it to run at lower RPM's further cutting noise. All caps, primary and secondary are Japanese made by Nichicon and Nippon Chemi-con. The fan is a 135MM rifle bearing, good but could be better with FDB. The fan curve, it does not turn on until roughly 250 watts and remains flat at roughly 600 RPM until 600 watts are being drawn. Designed to be bottom mounted I can't see the temperatures even without any airflow of being any concern. Just note it's not temperature controlled but watt draw controlled. If your system rarely sees power output up to 250 watts not only will you have zero noise but I'd suspect the fan will easily last the 10 year warranty. Fit and finish is very nice in standard matte black, beige accent around the model logo. 10 year warranty and Corsair does a good job with RMA's if you needed to. Intel C6/C7 Power State Support Ripple is extremely low and voltage regulation is one of the better currently on the market. Cables included: 1 x ATX CABLE 24-PIN (20+4) 1 x EPS/ATX12V CABLE 8-PIN (4+4) 4 x PCIe CABLE 8-PIN (6+2) 9 x SATA CABLE (3 SATA) 4 x PERIPHERAL CABLE (4-PIN) 1 x FLOPPY DRIVE ADAPTER (4-PIN) Speaking of cables, to further line regulation the ATX, EPS and PCIe cables have caps under the shrink wrap, this adds some extra thickness which depending on your case might make for tighter fit through openings. Voltage is flat, using a digital volt meter at the max watts my setup can output [236 watts] I get: 12.19V 5.02V 3.20V Protections: Over Voltage Protection Under Voltage Protection Over Power Protection Over Temperature Protection Short Circuit Protection Surge Protection Inrush Current Protection
Cons: No fan test button, if your system does not draw up the threshold you won't know if you have a faulty fan. I was able to by adding some external DC fans get the PSU fan to kick on briefly enough to physically see it working and it was dead silent so I am satisfied. This is certainly not a deal breaker.
Overall Review: Price is competitive for the gold rating, power output and features. Included velvet bag is overkill but nice and can be used to store something. Included nylon pouch with velcro as Corsair has been doing for many years is handy for holding extra cables not being used. Once you setup your system most likely you won't visit this pouch often. I have a junk drawer with a couple of these pouches just in case. Overall the V2 of the RM line has great fit and finish, excellent regulation, low ripple and zero noise until around 250W and even then the RPM's are so low you won't hear it. The real competition within price and features would be the Seasonic focus and prime lines. It's a tough choice, both are excellent units. Seasonic PRIME is currently $10 more, has FDB hybrid fan and even better voltage regulation and MIR. Focus is $10+ less Purchase factor resides in current sales and/or MIR and personal preference [past history] To date I've never had a faulty Corsair or Seasonic unit, many are 5+ years old and still rock solid. Personally if I were to purchase today it would be a tough call but I'd go with 550W, I simply do not need that much power. If Corsair offered a 450W unit I might be inclined to save a few $$ and go that route if it supplied enough cable options. Empty connections are wasted connections but allow some future overhead. CPU/GPU are becoming less power hungry as time goes on and the best efficiency is actually running around 50% load per any tech site if that matters to you. Truth is between Gold, Platinum and Titanium you might see a few dollars power savings for an entire year so it's not something to overthink even running 24/7. I hope you find my review useful and thanks to Newegg for the chance to review this item.
Nice but could be better
Pros: Nice sized unit, not too large or small and it's very heavy so it's not going to get knocked over very easily. The drive includes software and utilities for windows and Mac thus no need for a CD which is not included or you can download the latest from WDC's main site. The front LED is white which is nice for a change instead of the super bright blue that are usually used. Each drive has it's own LED which will be black unless there is an issue in which case they will turn red alerting you to a problem that needs corrected. Installation was as easy as plugging in the USB cord, power and allowing windows to install some drivers and it's up and running. The unit is packed very well in the box which is always good to see. It's not DOA, always another plus. The drives in this unit are of course WD RED drives which are decent, not the fastest but decent. Two included USB3.0 ports on the back to daisy chain another My book or another external enclosure. The Price is fairly decent if you take into account a RED 2TB drive is roughly $100 each thus the unit with raid controller is only $79 currently. I doubt you will find any external hardware raid unit for that price point from anybody currently. Made in Thailand, not China!
Cons: WD is a bit misleading on their stats. The unit comes pre-configured for raid0 which is why you have 4TB but you do not have two 4TB drives. The idea behind backup is redundancy, you do not get that with raid0. This unit has a built in 50mm? fan but it does not turn on until the RED drives hit 60C! thus the fan will never turn on making it pointless. [WD confirmed this for me] WD states the RED drives can "safely" reach up to 60c max which is extremely hot and will really kill the lifespan plus induce errors and bad sectors as the media breaks down. Not sure I'd trust my critical media to that environment. That said doing benchmarks and transferring some files I easily had it up to 48C [120F] which I find a bit warm. I could feel the heat rising from the top of the unit and the unit had a slight burning plastic smell. My Lian-Li case has a top fan and once I put the WD My book Duo on top so it gets some decent airflow through the bottom grills [and out the top] the drive temps dropped to 84F which is so much better for long life. I never planned to have this on top of my case as it is rather heavy to leave on top of a aluminum case long term. Another issue is the fact there is no ON/OFF switch. You can setup with WD software to have the unit sleep but if you want to physically turn it off and put it aside then your only option once you eject it is to pull the power plug. The unit has a 2 year warranty which I found odd as the RED drives have a 3 year warranty. The unit should at the least match the same warranty as the drives. The metal plate that covers the drives I had a slight issue with. In order to remove the drives WD supplies plastic pull taps attached to one of the pins on the back. Not sure how long those might last but they should unless you are constantly pulling the drives out. The metal plate has a metal tab, it was bent on mine not allowing me to put it back on and screw it down flat so the plastic top would sit flush once snapped down. I had to bust out some needle nosed pliers to fix this.
Overall Review: The power supply is not WD made or branded but Ktec which seems to come with all types of external enclosures. If it fails out of warranty it could be purchased. Read speeds are decent but writes speeds in both raid0 and 1 are quite erratic. It might just be the way RED drives work but it's certainly not a smooth graph as I am used to. It would be great to see a My Book with raid10 but this would of course double the cost and double the width but you would get the speed with redundancy. I want to note this unit uses hardware raid which is generally robust with one caveat. You cannot pull one of the drives out and install it into another PC and read the files. Also with hardware raid if you decide you want to try another version or JBOD the drives will be erased to backup beforehand. WD just announce RED Pro drives with a 5 year warranty which appear to be faster and even more robust. I would not be shocked if WD creates a My Book Raid Pro in the future offering those drives with a longer unit warranty. Overall not a bad external backup solution which a few things that could be improved. Crystal benches: Read speeds are decent but writes speeds in both raid0 and 1 are quite erratic.

Solid board if you don't want RAID
Pros: Great fit and finish, has everything you need for a board in 2021 Intel LAN, good audio, enough fan headers in the right spots
Cons: I research boards up and down before purchase but somehow missed this board does NOT have RAID ROM, Intel dropped it from the B460 and I was building my board around Intel RAID Had I know this I would have not had went with duel SSD and instead installed a PCIE 4x which this board includes a nice heatsink. for 4X the speed.
Overall Review: Smart fan 6 is slick, I like the fact I can set up adjustments on all my fans for temp/control.
Still the benchmark for SSD
Pros: Fast, runs cool, hits specs from Samsung Pricing has come down from a few years ago
Overall Review: Latest SSD 2.5 from Samsung and it hits all the marks One of the more reliable brands on the market. Currently have a 850 and two 860's and they have been rock solid for years. I expect the same from the 870
Pros: Extremely fast for being low end, runs about 10F over room temp
Cons: Heat sink is only aluminum and small but seems to be alright. Nidec fan is quiet, no idea what bearings it has. Mine was made in China which is strange, first processor from Intel to be so.
Overall Review: Would love to see Intel contract with Noctua to make a fan/sink with braided 4 pin.
A solid portable BT speaker
Pros: The Rosewill RW-SF5 Portable Wireless Bluetooth 4.2 speaker is a powerful quality built unit.It feels robust, it can get very loud even though it's only 8W X 2.Even at 100% volume it did not sound distorted and bass is good but not overpowering.The included accessories, carabiner hook and bike mount are nice.The 3.5MM remote control works well, no issuesvelcro strap is designed to attach to your bike so you can play/pause or FF without taking your eyes off the road for too long.6000mAh polymer battery is quite large and should suffice for 20+ hours of playtime.My unit arrived rather discharged, took a few hours to get to 100%Waterproof IPX4 and dust proof, did not test these features but assume they work to spec.USB DC out this unit can be used as a power bank to charge mobile phones, etc.Includes a USB to type B mini and 3.5mm to type B minimicro SD slot to store/play music.Built in antenna for FM radio, I was able to pick up a few local stations without static but I suspect it has it's limitations range wise.Music format: MP3, WMA, WAV, APE, FLAC
Cons: The pumpkin orange is decent and visible but more color choices would be great.Price point, at $60 with competition in this range or less with the same stats this could be a hard sellUsing AUX I could hard wire with a 3.5mm to my phone and play music, I could not attach my portable music player and get any sound.Buttons can be confusing, trying to play music my phone kept wanting to call out.Make sure to avoid this by going into BT settings on your phone and toggle off phone calls.There are different chimes for the various modes, it will take some some trial and error to get what you are trying to accomplish.
Overall Review: Does not include USB to USB type C which is what my Motorola smart phone uses thus if I want to charge my phone from this power bank I will need to purchase the cable.Not a deal breaker, cables are cheapI don't see the application 3.5mm to type B mini as any use, better would have been a simple 3.5mm to 3.5mm cable.I like this unit, pair it with a smart phone it does what you expect.Radio, you mileage may vary depending on location and strength SD card, without a way to scroll to folders or artist it's impossible to controlwhere you are at, for this you would need an LCD screen and file table.If you have 300 songs you will FF often to get to what you want to hear which I can see be annoying.
