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

Spent 3 hours replacing multiple components in my PC only to turn it on and have the new PSU do nothing.

Really quiet! I had picked up a seasonic focus gold previously and had some electrical whine that wasnt solved by a new unit. This corsair came on sale so I got this for the same price. Overall Im very happy.

Powers my 5950x & 6600xt fine. Dont have anything to complain about.

My old EVGA 850 had ridiculous coil whine under load, and I noticed performance issues far worse than expected of a 3080ti in Elden Ring. Sure enough, replaced it with the rmx 1kw, absolute silence and no noise under any load, performance is back up, and weird OS level freezes stopped happening too. My old 10 yr old PC has an AX1200 still kicking in it, corsair is quality. I shouldve never went EVGA for cost cutting, PSUs are worth spending on

I want to preface this review by saying I purchased this used in good condition from Amazon Warehouse for significantly cheaper- and while it did not come in the original box, it was packaged excellent, and looked brand new with all the cables and paperwork.

Got this 850x psu to replace a 750w. Corsair has alwasy made excellent products, and at the price i got it for, it was perfect. Easy to install, runs quietly (fan doesnt spin until it reaches a certain temp), fully modular which is nice since my 750w was not. I have always liked corsair and this psu is no exception.

great power works just fine in my tower

I am going to replace the cables it came with because they are bigger than they need to be. Still a great power supply thought.

A must to buy

You can find similar quality unit from the likes of seasonic but this is a quality item built to last.
