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

Easy to understand and setup. Great power supply for my 2nd gen Ryzen and multi GPU setup.

As always Corsair products are super easy to install and work great!!! Ive used Corsair PSUs in a lot of builds and have never had an issue with one. This one was no exception. Super quiet and performs perfectly!

My first unit came wrapped in foam perfectly packaged and the unit has a huge dent in it and you can hear the broken components moving freely when you move the psu. Returned and got a new one again perfect packaging I install hit the power button nothing. After testing this unit with 3 motherboards 3 CPU’s & 3 sets of ram all various brands it’s dead out of the box. Having never owning a Corsair power supply before & getting 2 dead units I will never be a customer again. Wouldn’t recommend but maybe your luck will be better than mine

Some thick power cables that go from the power supply to the motherboard have wire mesh sheathing, and where the sheathings end, there are what seems to be thick heat shrink tubes to hold the ends. These tubes are so hard that the cables dont bend at all on the tubes, which can be a serious problem in routing cables inside the computer case. Also because of this inflexibility, it puts a lot more stress on the connectors on the motherboard.

So, just the facts. Purchased this from Amazon Warehouse as Used - Like New. Box came still sealed in shrink-wrap with only a small scratch on the outside. Everything inside was brand new. Great deal I thought.

So easy, even a non techie can install it

Great product. Great price!

Easy install upgrading from 650 watt full modular

Arrived earlier than expected. No damage. Works perfectly so far.

Was looking for a quiet 800 Watt PSU and this was the one. Also slightly smaller than expected! 10/10
