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

great power supply simple as that it works and quiet

Easy install upgrading from 650 watt full modular

Product broke after a week after being installed.

I used to trust corsair which is why I went with this psu. Upon installing, routing cables, and then powering on (or rather try to power on) I found of my unit was defective. I would be able to look past a mouse not working but a power supply? Inexcusable. Avoid this product at all costs. Corsair is laughing all the way to the bank with your money. Tried the same setup with another psu and it fired right up. Corsair has forever lost a customer.

All modular and easy to install. I never had a Corsair component fail. Ive bought 8 in the past 10 years in my builds, all still work.

This thing is awesome! If you are a novice PC builder I would reccomend getting a semi-modular because some of the wires are universal and you dont really need the modular capabilities unless youre getting creative.

I used to buy nothing but PC Power and Cooling PSUs because of US company loyalty and a trust in quality superiority and an understanding as an Electrical Engineer that PSUs are the oft neglected but nevertheless single most important piece of hardware in any electronics. I have a 5 year old Corsair 850 that has been flawlessly reliable and solid and I bought this one though Im still using the old one on my Main. This new one is for a secondary box. I was a little surprised that it is even better than my 5 year old model. Im good for at least a decade. :)

For a few bucks more I opted for something thats a bit overkill, so it will run quieter (since it isnt working as hard), and will last me for 10 years.

Defective PSU. Spent half a day trying to figure out why my motherboard kept turning on and off, and never expected a brand new PSU would be the problem. I have much higher expectations when spending $320 on a PSU.

Nice power supply but it failed after around 200 hours run time.
