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 used Corsair products for a long time. They have a great reputation and customer service. This PSU was a breeze to install thanks to its modular cables. Plus, it has a ten year warranty.

I upgraded from an older Corsair PSU that had pretty noticeable bearing noise on the fan. I figured after 7 years its time was up so I went with this highly praise PSU. 750W is enough to power even the beefiest of systems thanks to increasingly efficient components. My new rig has a focus on silence so a power supply with zero RPM fan mode was a must. I have no regrets since putting this in my system a few months ago.

Rock Solid modular PSU. Not much more to say, really. Does its job. Does it quietly and reliably.

Arrived when expected, performs as expected.

Replaced my old stock PSU with this. Chose this instead of the newer 2021 model due to lower noise level.

I have read sooo many people complaining about the quality of the product but so far I havent had any issues, it works just as I expected. Will update this review if something changes, but while that doesnt happen. It is great

I have this connected to my RTX 3090 and i9 10900k, and it works perfectly.

works perfect!

My computer needed some extra power and so when I was searching for a battery replacement, the dimensions had to be about the same size compared to my 550watt battery. This one specifically met all the size requirements for my tower AND packs a punch. Installation was easy and its super quiet.
