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

Happy

I havent tried Corsair power supplies in a while but I thought I would try this model for a new htpc build since it was highly rated and was supposed to be very quiet. Unfortunately it was DOA so I guess Im going back to EVGA power supplies.

Its a PSU. Its Modular. Its 80+ Gold. Its a reliable brand.

It runs silent and works just as expected.

Have used Corsair products for a long time. They have a great reputation and customer service. This PSU was a breeze to install thanks to its modular cables. Plus, it has a ten year warranty.

Does what its suppose to. The fans hardly ever have to spin when gaming.

will never go back to a non modular power supply ever. this power supply includes capability to disable cooling fan at low to mid level power demands to save on noise while remaining 80+ efficient or better. will buy again for another build

es de lo mejor que he tenido

A nice upgrade for my desktop PC.

First, I will say that this power supply solved my issue of an underpowered video card. The modular connections are also nice. It comes with more than what you will need. Unfortunately, it did not come with the power connector that goes to my DVD drive, so that was disappointing, but I dont expect them to be able to cover every single configuration out there. This power supply boasts a fan system that doesnt run unless it really needs to. So, when I first powered up my system with the new power supply installed, I was instantly impressed on how quiet my PC was. However, as soon as you do anything that draws more than normal current (video game, graphic design, etc.), the fan spins up. I have worked with computers for over 30 years, most of that as an IT professional and I have NEVER heard a power supply as loud as this. (SEE UPDATE BELOW) So one has to question WHY is it so loud? I should have listened to the reviews about the noise. I figured it cant really be that bad. It can...and it is. Other than that, it seems to work great. Unfortunately, I always have this uneasy feeling that my PC is overheating because thats the only time you usually hear noise like this. Yes, because of this power supply, I live in a constant state of panic. Luckily, my headphones block a lot of the noise but they shouldnt have to. 12/19/21 edit - I recently changed my hard drive to an SSD. When I installed the SSD, I removed modifications I made to vent heat from the video card. After this change, the power supply has been running quietly with only a bit of a whirring noise when I am using heavy graphics. So, I am revoking my previous 3 stars and adding another star because it seems with the right PC config, the power supply operates at a reasonable noise level - even at a superior noise level when not doing heavy graphics.
