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

Have always had great luck with the performance and stability of Corsair products.

Its a very quiet Psu and even when its under load it doesnt get too loud.

Right out of the box the unit would not work and Amazon will not allow me to return. The return window is so short, geez, sorry for having a job and it taking me a little time to get around to working on the computer. Long story short, dont buy this piece of junk!

I already have experience with corsair power supplies and I have become a fan of the brand. This is my second corsair and I have had nothing but positive experiences with the brand. Thank you.

Great product from Corsair as always, works well, packaged nicely, great quality.

Great product

Silent when in use, easy to install, very nice build quality. Love this thing

Competitive pricing.

Bought this POS because it was highly recommended and Corsair has a good reputation as a brand for a top of the line PC build (x570 mobo, ryzen 9, etc). The first one died the day after installing it, after my computer went into sleep mode and something must have tripped electronically because it went dead instead. Replaced it, second one seemed to be working fine for a week, then the lights flickered for a minute and the thing completely died again. Both times, it was on a name-brand surge protector and was the only device that had an issue. I had another of these PSUs on hand for a duplicate build, but Im returning it and this DOA one. The 8-year-old Rosewill PSU plugged into an almost decade-old build thats been running 24/7 next to this brand new build 4x the price had no problems through these little flickers, despite being on an off-brand surge protector. One could have been a fluke, but two in a row going completely dead over the tiniest fluctuation in power says its a build problem. Im not rolling the dice with another and letting it fry my motherboard this time.

A little louder then I expected from the reviews. However, everything works great and its not unbearable. So overall happy as I can be
