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

First one I received. Had a error that the switch would not shut the energy off. So I could not use it. Replacemente came in. Works perfect. Happy customer

Works well, there is a hum to it, but other than getting hot without proper case cooling, you shouldnt have any issue.

Bought this to replace my older unit. Love being able to only plug in the cables I need and having all black cables instead of those hideous mustard and ketchup cables.

This product does just what it says it will do. Even under heavy gaming, its still pretty much silent. Packaging was excellent and I will continue to buy Corsair products in the future.

Set up easily, everything was running fine for about 2 weeks. Restated after some software updates to my computer and everything crashed. Did paperclip test, PSU dead. Swapped with another PSU, motherboard dead. New motherboard with swapped PSU, no boot, CPU fried. Buyer beware, killed my whole system.

My RM750x lasted less than two years.

Simply put amazing reliable product by Corsair. Which is no surprise but it works with no difficulties.

Me agrado mucho su calidad general, al ser modular se puede arreglar todo cómodamente y es muy silencioso y eficiente!

Got this to test motherboards, old ones and newer ones. Works great. Simple power switch, which is a little small compared to larger one I have on corsair HX1000 and HX1200, but it works fine. Not a big deal. Nice power supply, been using a 2 or 3 months at this point, does a good job.

I purchased this PSU to replace a lower wattage Corsair TX series unit. For most people, 850 watts is overkill. However, the RMX line is of high quality and has many features such as a zero RPM fan mode, full modularity, and 80 plus gold certification. I have no qualms recommending the RM550X, RM650X, RM750X, or RM850X for anyone that desires these features as its probably one of the higher value full modular, gold certified units on the market. Especially so, for its sale price!
