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

Most of us choose a power supply by price.. but if you want reliability, 30 years of building computers has taught me to stay with Corsair. Also, the one time I had a bad PSU, Corsair paid for the return labels and handled everything quickly.

Fixed my pc. I used a PowerSpec 850 as MicroCenter did not have a Corsair. I had all kinds of boot hangups, non boot, power offs. Gave up and bought this supply. All issues gone. Pure joy.

Exactly what I needed. With shipping, better price than anywhere else.

Sata cables are only useful if you have drives stacked on top each other and enough space to fold the extra length. If your drives are placed vertically like most high-end cases do now, you need to get an extension to make it more manageable.

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!

Performs fantastically, cant hear it at all. Using it to run an i7 5820K OCd to 4.1GHz with 2x EVGA GTX 580s on an ASUS X99 Sabertooth and it gives me no issues whatsoever. And its Corsair so its got a practically never-ending warranty. Been running it for over a year and its not stumbled once. Highly recommended.

I am really impressed with the stability and performance of the Corsair RM850x. The 850 watts of power is more than enough to handle even the most demanding games and applications, and the modular design makes cable management a breeze.

In comparing different models of power supplys, the Corsair seemed to fit the bill, be highly reviewed (especially for this model) and be at a good price point.

Decent PSU, very quiet. The cables that come with the unit are a little stiff and might have issues getting through the cable management holes. Investing in braided cables or extenders might be a good idea.

All is good run graye
