CORSAIR - RMx Series 850W ATX12V 2.4/EPS12V 2.92 80 Plus Gold Modular Power Supply - Black

Power supplies are normally the least glamorous part of a pc build, but can be the most important component. I upgraded from a 650 watt bronze certified no-name brand to this Corsair 850 watt beast to support my new RTX 2080 with the potential to run SLI in the future. This is a fully modular unit which cleans up the interior of your case and makes cable management a breeze. The cables that come with the power supply are clearly labeled, are all black, and come neatly packaged in a svelt little carry bag. Everything you need to install this power supply is included. Once I got everything installed and all the cables routed, I fired up my computer. This power supply is quiet and power delivery is smooth. I’m very pleased with the looks, build quality, and performance from this Corsair RMx850!

I owned the CORSAIR - CX-M Series 650W and thought I would give this one a try since I was seeing issues with gaming and other CPU intensive programs. I really started to see more of this a month ago, after getting an HTC Vive. Nothing was stable and kept crashing. So perhaps I didn't have quite enough watts or it was a slowing dying PSU which was also starting to make more noise. My specs are an I7-6700K, 16 GB DDR 4 RAM, GTX 1080, several HD/SSDs and quite a few fans including a Cooling Master for the CPU. Played on my PC for much of the day today with no issues. I'm amazed that fan doesn't even turn on that much and it's very quiet now.

I bought another pc and moved my GTX970 into it. I had put a cheap Chinese 650W power supply in it. Under normal use everything was fine, but when I went play games, the speakers would buzz, and the buzzing wasn't tied to the volume of the speakers. Even with the speakers on MUTE it would buzz. I tried several things and then became convinced it was the cheap components of the power supply causing it. I purchased this Corsair and not only is there absolutely no noise while gaming, there's virtually no noise at all from the power supply. Corsair packs it well and the modulars cables come in a nylon bag! It was easy to install and route the wires.

My 750W supply from another major brand failed suddenly, causing me to scrabble to find a local supply in order to meet a work deadline. This 850W was on sale and in-stock, so I grabbed it. I couldn't be happier. The modular design helped clean up my case, and the unit is silent. The CPU power cable was barely long enough for my configuration, but the rest had ample length. All the power cables are sheathed.

Decently Good Power Supply A good reliable and affordable power supply is needed when putting together a basic gaming machine. The price point was where I was looking at and this would fit the bill on a computer build that is coming together slowly. It's definitely a keeper for know on what is being build.

I can't think of a reason to fault this unit. It was well set up and and easy to install. It's very powerful and relatively quiet. It comes with plenty of plug options and decent cable management options. I've been running it for about 6 months with no problems on a medium power hungry rig. Overall, great unit.

It is powerful and efficient. More than enough for the best gaming systems and modular for great electrical efficiency and no extra unneeded wires in your case. Software available that can monitor efficiency and heat. Best technology for a great gaming system.

This PSU is a power house. With Gold Efficiency, it can help reduce your electricity bill a bit. The cables are very sturdy, at one point, it made it tough to plug in because it was not as flexible. The PSU is very whisper quiet which is pleasant. Can't go wrong with Corsair!
