Corsair RMX White Series (2018), RM850x, 850 Watt, 80+ Gold Certified, Fully Modular Power Supply - White, 80 PLUS Gold (CP-9020188-NA)

This power supply is definitely one of the best. It’s super quiet and efficient. Plus how can you go wrong with the white cables that are included AND labeled! Installing this thing is easier than blaming your dog when you fart I kid you not. My last Rosewill psu sounded like a Boeing 747 taking off so it’s nice to finally have some quiet while my pc is on.

I used this Corsair RM650 to upgrade the PSU in a gaming computer that I originally thought didnt need a PSU of more than 500 Watts. Now, a couple of years later I want to add a new video card, and an upgrade was necessary. This PSU is of superior quality, well-designed and constructed, with good materials, and the modular feature keep the interior of the case organized, and it also it lets more space for ventilation. Because one only has to install the cables that are being used. The modular design also makes it easier to install, and I could notice an improvement in performance, which I wasnt expecting. I simply wanted to have the voltage to handle the new GPU, but it has improved the machine altogether.

Upgraded from a 550 off brand that came with my original build. Biggest upside was that my original was. Not fully modular and this was. Like why do they even make power supplies not fully modular? This was a huge step up for me.

Probably the easiest and most enjoyable time Ive had building a complex loaded PC - cables are great quality and length, super super quiet.

Corsair is a well-known and trusted name in computer applications. From Solid State technologies to power applications, their products are widely adopted by an array of end users. I am no different. Through the years of building my own computers (rather than buying pre-built), I have used many Corsair products (mostly their memory). This power supply is no exception from what Ive come to expect from Corsair. Solid, reliable performance at a reasonable price. Power up is VERY quiet, and no hiccups in power disbursement. In a custom tower, this form factor fit VERY nicely, and is surprisingly light weight. It does run a little warm, but nothing that indicates that the performance will be impacted. As far as longevity is concerned, only time will tell. However, from my past experience with Corsair products, I dont foresee having to replace this PSU for a good long while. In fact, I would be willing to bet good money that this PSU will see multiple mainboard replacements before needing to be replaced.

Beware to all those who have a Micro ATX case. The Power Supply itself barely fits into the case, but once you need to put the wires in its all over. Returning it immediately.

The power supply was dead on arrival. I used the same AX850 for almost 8 years before it gave out. This RM that I ordered lasted 0 days. Returning asap.

lol

Overall a great product. The unit fit inside of my box perfectly, no issues. Love it, so glad

Plenty of room to upgrade and always been reliable
