Corsair RM850e White 850W Cybenetics Gold ATX 3.1 Power Supply

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.

Priced like a premium product but packaging, finish and features suggest otherwise. Cables dont have a premium look or feel, no silent mode switch like other psu's and packaging is very basic.

Aside from that works like a power supply should... Priced like a premium product but packaging, finish and features suggest otherwise. Cables dont have a premium look or feel, no silent mode switch like other psu's and packaging is very basic.

Brand new custom pc build, run through diagnostics + stress testing perfectly. Brand new custom pc build, run through diagnostics + stress testing perfectly.

For the price I get a decent power output, so I won't have to worry for minor upgrades to my PC in the future, all the while it maintains the existing parts perfectly.
Wasn't sure about the physical fit, as the dimensions made it seem quite a bit smaller than the last, but it was all fine in the end.
Definitely good value for the product. For the price I get a decent power output, so I won't have to worry for minor upgrades to my PC in the future, all the while it maintains the existing parts perfectly.

Bought to replace lower wattage PSU, was a perfect replacement no issues. Bought to replace lower wattage PSU, was a perfect replacement no issues.

Got this for a new build and have been really impressed - the cables it comes with are really nice and clearly labelled, it comes with a matching white power cord, and it's small enough to fit in my case which only has a small PSU compartment. Does what it's supposed to with no issues. I'm really stoked with this overall and would recommend :) Got this for a new build and have been really impressed - the cables it comes with are really nice and clearly labelled, it comes with a matching white power cord, and it's small enough to fit in my case which only has a small PSU compartment.

A generally good PSU, efficient, well priced, good warranty.

But beware the low amount of PCIe outputs (only 3) on it. Many products make use of these and you may need more. I would recommend the RM850x or RM1000e to get a few more outputs. A generally good PSU, efficient, well priced, good warranty.
