Corsair 850e
Great product, runs very well, doesn’t get very hot, it’s very quiet and overall just a awesome power supply, I used in my high end gaming pc and I’ve had no problems!

Great addition to any pc
Plenty of cables to get the job done plus it’s modular so no extra cables to hide, near silent operation when fan is running and completely silent when fan is not. Fans will not run under low load/temp in turn this means less wear on fan bearings, less dust, and longer life. 10+ years of pc building and gaming experience has proved Corsair is a leading manufacturer for a reason, their parts just seem to last and work well given they are installed properly and used within the correct thresholds.

Rock-Solid, Quiet, and Future-Proof Power Supply
The CORSAIR RMe Series RM850e has been an absolute powerhouse in my build. Installation was incredibly easy thanks to the fully modular design—I only had to plug in the cables I needed, which made cable management super clean and kept the inside of my case looking organized. Performance-wise, this PSU delivers flawless, stable power. With the 80 PLUS Gold efficiency, my system runs cooler and more efficiently, and I’ve noticed zero coil whine or electrical noise. Speaking of noise—this thing is practically silent. Even under heavy gaming or rendering loads, the fan barely kicks in, and when it does, it’s whisper-quiet. What really sold me is how future-proof it is. With ATX 3.1 and PCIe 5.1 compatibility, it’s ready for the latest and upcoming GPUs without needing any adapters. It gives serious peace of mind knowing my system is set for future upgrades. The white finish is a huge bonus—clean, premium, and perfect for white or themed builds. Overall, the RM850e is powerful, quiet, efficient, and built to last. If you want reliability and modern standards in a sleek package, this power supply is a fantastic choice. Highly recommended!
