Corsair RMX Series, RM850x, 850 Watt, 80+ Gold Certified, Fully Modular Power Supply (Low Noise, Zero RPM Fan Mode, 105°C Capacitors, Fully Modular Cables, Compact Size) Black

First thing I did is throw it on my PS tester before installing, and all voltages were spot-on target. One voltage slightly higher, but well within acceptable parameters.

Corsair does it again, huge improvement over EVGAs psu. I went ahead and got this after An EVGA psu failed to perform well. My Corsair is not only silent, it pushed ass my RGB, 2080 and oced i7 8700k perfectly. Could not be happier. The included cable bag is also a nice touch.

This unit seemed to work fine for a couple weeks. I installed it along with my new GPU, but then had to leave for a trip for about four weeks. When I got back, despite having changed nothing, my PC started randomly crashing -- what was clearly a power-related hardware problem. GPU and CPU werent overheating. Cables were all secure. Windows event log had no errors recorded. Crashing would happen at random times in random scenarios, sometimes 20 mins after boot, sometimes 6 hours. Well, what can I even do? Buy a new power supply and see if the issues persist. Spoiler: they didnt.

its been nearly three years and it has yet to fail. <3

I bought this product and it came broken. The fan wasnt turning on and it was overheating. It got super hot and was increasing the temp on my gpu and cpu and motherboard. I ended up returning it and wanted to just be honest and tell others the product might have a problem and could cause serious injury or destroy your pc. So if u get this make sure your fan works and ur cpu isnt overheating.

Great power supply, 10 out of 10 on Johnny Guru testing. I am running a heavily overclocked intel system with twin gfx cards in x-fire with zero problems.

Would have give them 5 stars on all, but please dont do my mistake! THEY dont use same pinnout as other for their SATA cable. If you are replacing a non corsair PS, remove and throw away all old sata cables and use the one in the box, or say goodby to all the sata drive plug at the other end. Cost me 3!

I got RM750X for my new desktop, with Core i9-10900K. Although I dont use a graphics card, the 10-core (20 with hyper threading) 5Ghz CPU could use a lot of power, so I got a probably much bigger PSU than I need, just in case. Installation was a breeze, the PSU fit well with NZXT H71i case. Its nice that this PSU is completely modular. So far the PSU has been so quiet I cannot tell the fan is moving (it is), and I havent experienced any power issue with the rig. I am happy with my purchase.

The ATX cable wasnt in the box like its supposed to be, so literally unusable. Thanks amazon :/

The heat shrink on the cables makes them a bit difficult to manage. I successfully trimmed the heat shrink in a few places, but almost went too far on the 24 pin cable, 2 splices are just out of sight so only trim a little at a time if you do the same. Otherwise no complaints.
