Corsair RM850e 850W ATX 3.0 Power Supply

It’s a power supply , it powers things .
Nice to have new gen features but it’s annoying that it doesn’t have enough Pcie 6+2 cables in box to run 3 8pin connection to gpu, and PB tech doesn’t have any cables to supply after the fact .
Has quite an audible click when power down . It’s a power supply , it powers things .

at the time of purchase this was the only available option (not my first choice). Some people complained of EXCESSIVE coil whine but i dont really notice it. I would go with the MSI MAG 850w if pb had in stock. at the time of purchase this was the only available option (not my first choice).

So far this is an excellent product. I can not fault it at all, 5 out of 5 stars. It's extremely quiet when running, the quality of the PSU and the cable wrapping is very high. They've supplied more PCIe and CPU cables than I need, they've even packaged a longer than usual HDD cable should your drive be on the other side of your case.

I installed it into my older PC that suddenly decided to no longer power on. This PC was put together in 2017, it had a ZM600-GV from Zalman. The Corsair RM850e is a nice upgrade of 250W to a grunty total of 850W. It fits beautifully into the old Cooler Master ATX case, really easy to get in there with no scrap...view more So far this is an excellent product. I can not fault it at all, 5 out of 5 stars.

With the Corsair RM850e you get your standard 4 screws and about a dozen cable ties to keep everything tidy. The motherboard, PCIe, CPU, and additional 6+2 or 8 pin connectors are of great quality plastic. Everything is really nicely done, nothing feels cheap or tacky.

A note to those self-installing this kit into an old PC whose BIOS might not pick up on the change of supply: be sure remove your CMOS battery while powered down, then put it back into your motherboard before powering up. This trick was needed before my BIOS would boot the machine after installing the Corsair RM850e. Not a fault of Corsair at all, just an acknowledgment that a 7 year old BIOS needs to be kicked in the trousers now and then so that it realizes something has changed between power cycles.

great price, pc working smoothly. great price, pc working smoothly.

Works well, does what it is supposed to do.

Have used for about a month so far - no issues. Fully modular, easy to have tidy cable management. Works well, does what it is supposed to do.

Using with a 4080 super and 14900k and runs stable.
Nothing much to say about the unit itself (not the most exciting component of a PC really) - had enough cabling for what i needed. Using with a 4080 super and 14900k and runs stable.

Works super good, tidy cables, easy to plug in all the wires etc. Definitely recommend. Works super good, tidy cables, easy to plug in all the wires etc. Definitely recommend.

If you can’t find the PSU you really want, then at least this is an A-Tier option according to the PSUCULTISTS 17.0G rankings of PC power supplies.

It doesn’t feature braided cables and the shiny black ribbons are a bit jarring for a 1000 watt unit. They don’t look good plugged into the GPU! If your case can fit the power cables running out sideways, the SHIFT PSU is newer and better, but this definitely does what it is supposed to do. It provides 12V/5V/3.3V at very clean, stable levels.

I have no complaints about noise, and it is silent at PC idle/ low power draw. If you can’t find the PSU you really want, then at least this is an A-Tier option according to the PSUCULTISTS 17.0G rankings of PC power supplies.
