    It seems a little louder than other psu I had but works well and seems of good quality.

    Easy installation, comes with all the cables you would need (3 PCIE cables), comes with a good amount of slots, and I cant even hear it run when the fan is on, but the fan is only on about 1/3 of the time. I am using this for a mining rig operating 24/7.

    I bought the RM850 to replace a Zalman 1000w that died (after 12 years!) during a black out. It was easy to install and it works great, zero problems. I especially liked the completely modular cabling. Nothing comes out of the unit. All cables plug in, so no extra dangling cables inside the case. Also the dual 8-pin PCI-e cables feed into the graphics card with only one cable coming out of the PSU, as you can see in the picture. Great cabling throughout!

    This fully modular power supply performs admirably. It is quiet when demands are low since it responds to low demand by seldom activating its fan. When demand does increase, it is still rather quiet, reaching a moderate 22 decibels. The most sound it produces on my Corsair 200 case is 24 decibels during full gaming.

    Upgraded from a Zalman 1000 watt unit from 2008. It worked fine but it was over a decade old and didnt feel like cheaping out on the p/w supply after I upgraded every thing in my pc to state of the art. Feels solid and love the modular design of the unit. Makes wire management a breeze. Unit is quiet under load as well. Not sure about long term reliability? Hopefully I get a 10 years out of it like I did from the Zalman unit this one replaced.
