decent price, cables were just right for my case, power was more than enough for what I needed, most importantly, the modular power supply means I don't have any unnecessary cables that makes my build look messy.

Although the PSU is a little louder than preferred it works perfectly maintaining my 3060TI and all other components of my PC. I am very happy with its affordable price and suggest it for all users who would like to run high demanding PC's.

I’ve been building computers for over 10 years at this point and I’ve only used Corsair PSUs.Back in the day it used to be the CX550m for the low cost and great components but 550w just wasn’t cutting it for me anymore.So for my personal system (R7 5700x and RX7900GRE) I decided to go for something with a bit more headroom.The power supply fits great in my Fractal Design North and cable management wasn’t an issue thanks to the modularity of the unit.I haven’t had any issues with noise or heat and the extra headroom for wattage allows for my system to reach its full performance and allows for some nice OC.I’ve read some things about coil whine from this unit but I can’t attest to this myself and I’ve been running it for over a month now.

The power unit is fine. Weighty, well made and plenty of connectors in the box. I look forward to using it. One star lost for delivery, which was a sham. It's marked as handed to resident. He totally lied, again. It was left on a neighbours back doorstep in plain view of anyone who fancied it. They don't wait and they don't care if your sensitive electronic component is destroyed by rain, so be advised.

Bought to pair with a Ryzen 9 7950X3D and Radeon 7800XT and runs both without issue. Have no plan to overclock but even at highest quality gaming there's plenty of headroom and have had no issues.Cables feel like great quality and are also really nice lengths. Don't see them failing and can see them lasting the life of the pc.Only odd complaint is I found some took a bit of force to actually lock into the power supply, may of just been mine or maybe slight molding issue with the connectors but it's only slight but thought I'd mention it.

I almost always go with Corsair for power supplies, and this RM850e just proves why. Rock solid, quiet, fully modular, and built with quality components. It may cost a bit more than some brands, but the reliability and peace of mind are worth it. Perfect PSU for a stable build.

Howdy,I've been messing around with pc's for over 40 years but I still love gaming.My "old" PC was due a reboot, the GTX1060 just wasn't cutting it anymore and having recently bought a Samsung Odyssey G8 Ultrawide it was quite literally dying trying to power games in 3440 mode.So I bought a 4070 Super. Amazing what an improvement but the wiring from my old PSU with all the tethered cables was a nightmare. I read some reviews on this Corsair and dived in, took about an hour to get the basic install done and then about 30 minutes hiding and managing cables where possible: in a very old case that has zero cable management (Antec 900) !!End result is very tidy compared to what it was, could be better in a newer case but that will have to wait until payday!HOWEVER: !!! The best bit !!! IT HARDLY MAKES A NOISE !Its almost silent running and as the tower sits on the desk next to me the original PSU was unbearable. Its honestly gobsmackingly quiet !(the top fan cover needs reinstalling but that requires a complete stripdown, hence the black tape in picture!!)System specs for geeks:Windows 11Intel(R) Core i7-9700K CPU @ 3.60GHz64GB RamNvidia ATX 4070 Superx 2 m.2 Gen 4 NVME's (6TB)x 1 SSD 2TBAll sitting on an MSI Z390 Tomahawk MB
