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

I never hear it running.

My old supply still works but it made an unfortunate noise at the fan so I purchased this one and I like that the fan operates only when needed because now with speedfan my pc is practically 0 db now when not using it for cpu/gpu intensive tasks. The 750x does make a switch noise when you turn it on but apparently that is normal though my old supply didnt do that. I dont need 750w but its around the right number 650w would work to.

Good power supply

Since the covid 19 pandemic power supply prices have been crazy high. So now when possible one buys only the number of watts needed in a power supply. Yet one never wants to sacrifice quality on the alter of excess frugality. Corsair generally makes quality computer equipment and even cheaper bronze level its power supplies are better than the no name un-certified power supplies.

only the 2nd most powerful psu ive ever bought and yet it provides the longest life and very quiet and sooo much more power and clean power even in a brown out my pc never skipped a beat and it loves my battery back up power

Bought this psu when it was on sale, initially had the rm750, but decided to upgrade to this. Quality of the unit is great. The cable is a bit stiff though and was a bit hard to manipulate, however after a bit of tweaking, I was able to connect it to the mobo. Haven’t heard the fan noise too much, I do use a headset for gaming and for normal computer use, it’s not intensive. Overall great product and highly recommend it

Very good product

I had trouble fitting it and the cables in my case but thats obviously because I under estimated my cases size and even then I was able to fit it in with the Hard drive cage so Id watch out for that but overall Id definitely would recommend it if you wanted a decent PSU.

Got this as part of a new build. Its the first power supply that has come with cables exactly as needed by the rest of the system. Its modular so initial unpacking was a surprise till I figured it out.

Powers my computer perfectly.
