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

Havent noticed any issues or power fluctuations. Just steady continuous wattage and thats all I want from a PSU.

Modular and leaves you with power headroom for upgrades.

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.

It’s worth buying for your pc

Great PSU. Full modularity is great, run only the cables you need. Plenty of power even for higher end systems.

Dead on Arrival! Doesn’t work. Seller won’t allow exchange or return because I am 1 day past 30-day window even though it has never been used. Don’t buy from this company. No willingness to make things right when product is defective.

I build alot of computers and Ive never has an issue with corsair psus. I prefer evga by a long shot. the cables are better and unit to me feels better. only reason I gave 4 stars instead of 5 is the cables. unit works great

My college aged son is in the process of building his own gaming PC. We tested it out on his old PC since were still gathering components for the new one. This power supply runs quietly and works as expected. Cables were included and it was a breeze to set up.

I am running a high-end system, and it handles the load so easily that I rarely see the cooling fan even come on.

Not the MOST efficient. Not the LEAST ripple. Probably good enough for 99%+ of DIY PCers.
