Corsair RM850e White 850W Cybenetics Gold ATX 3.1 Power Supply

Great price. Fully modular cable system allowed me to get rid of unused cables and tidy up space in my case. Great price. Fully modular cable system allowed me to get rid of unused cables and tidy up space in my case.

Highly recommend for someone looking to get a high tier PSU for an affordable price. Moodular is definitely a bonus Highly recommend for someone looking to get a high tier PSU for an affordable price. Moodular is definitely a bonus

The cable structure is a little odd (the individual wires are loose rather than being stuck/sleaved together) but it was easy to set up, performs as expected and is quiet.

I swapped cases and needed something smaller to fit nicely into the new case. Really happy with this Corsair, great cables, good quality and nice and easy to put in. Works well and isn't too loud.

psubis easy to set up had all the cables and more for all my needs. psubis easy to set up had all the cables and more for all my needs.

This is a replacement for a AX760i that started having issues after 13 years. The RM750e was a very easy install, the cables have loose wires which makes it very easy to route, easier than the old PSU. It doesn't have a whole heap of outputs but plenty for my simple back up computer build and has the new GPU output for futureproofing. Good value for money, highly recommended for a non-crazy build.

I needed a reliable PSU quickly to get my Epyc 7302 server up and running. People will say "get the 850w" but other than 100w additional headroom the 850W doesn't provide any additional cables compared to the 750W.

And of a 750W I can run such a massive processor and lots of spinning drives, midrange GPU and SAS card, so those who say "750w is not enough", think again. If I can run such a massive 155W processor of this, your system will be fine. I needed a reliable PSU quickly to get my Epyc 7302 server up and running.

I've brought two of these and as far as I can tell this is comparable with my RM1000x BUT it comes with less cables.
If you need more than 2x8 pin PCI-e(graphics card) then you should consider a different PSU. I used some spare type 4 cables I had with my RM1000x.
I also like that corsairs cables aren't wrapped, makes it easy to fit between the back panel and the motherboard support. I've brought two of these and as far as I can tell this is comparable with my RM1000x BUT it comes with less cables.

There is a list of cables that I did not pay attention to in the description. My GPU requires 2x8-pin power, but this PSU only comes with a 12V 2x6-to-2x8-pin adapter cable and one 8-pin cable. As a result, I had to use the infamous melty 12V 2x6 socket. The PSU includes 3x8-pin connectors (CPU, PCIe, PCIe), but the necessary cables are not provided, and it is difficult to source additional ones.

Quiet, efficient and reliable PSU, great! Quiet, efficient and reliable PSU, great!

Got this for my new pc build. Looks nice and goes well with my white them setup. Got this for my new pc build. Looks nice and goes well with my white them setup.
