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 installed this PSU in an existing setup. However, anytime I tried to shutdown my PC (either through Windoughs or through the power button on the front of my case), the PC would shutoff, and then instantly turn back on.

I will NEVER buy anything but modular now.

TL;DR: Top quality at a reasonable price point. Buy it already!

Was sent a defective unit. After troubleshooting with the manufacturer an RMA was opened. This would be fine but they want me to pay for shipping to them, so by going with this company I not only have to wait weeks to get to use my product, but I also have to pay more money. seems I should have simply gone with a more expensive company that actually does QA.

Le hacían falta el cable AC, ATX, 2 cables SATA, 2 Peripheral y el adaptador de Floppy, lastima, no pude ni probar la fuente. Muy decepcionado.

Lots of connections for all those extras to connect power to. Plenty of wires included.

My PSU worked great for almost 3 years. Without warning, it died. I requested an RMA through Corsair and weeks later, all I get are excuses of why Corsair isnt sending me a replacement. Until it failed, the power supply worked great. However, the warranty and customer service definitely leaves me frustrated and stuck. Corsairs support has no interest in resolving the RMA it seems. If you expect that this will outlast your new PC build, go for it. But, if you have any concerns that you may have to have this replaced, I would definitely recommend caution.

I bought this PSU from another retailer the very end of Dec 2018. By mid Feb it was loosing power and causing the system to randomly reboot. I did my research on this build. There were no compatibility issues, and I am not a power user or hard core gamer. This is a faulty unit. It was outside of the other retailers window for a return. Which is fair. But Corsair is supposed to have a warranty policy in place. But when I went to Corsairs site the button to submit an RMA ticket was licked to a page where they basically said they were to busy responding to issues to take new tickets. Because of this experience it will be very hard for me to ever buy a Corsair product again. Very disappointed.

I went with a 750W only because the 850W was on backorder. Im happy with it so far, it runs relatively cool and quiet (almost completely silent - Ive yet to hear the fan noticeably spin up under load, Ive had to actually put my ear up to it). Came with plenty of cables and a neat bag to store them in.

So quiet even under high demand! Under low load, my chipset and vid card fans are more noticeable.
