    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!

    Needed a PSU with plenty of power for any GPU I want to throw at it. New OEM cables are nice and clean. Good warranty.

    The CORSAIR RM850e PSU is a fantastic choice for any high-end build, especially those focusing on white aesthetics. Its 80 PLUS Gold rating ensures superb efficiency, while the fully modular design keeps cable management clean. Crucially, it supports ATX 3.1 and PCIe 5.1, providing essential future-proofing for next-gen GPUs. The low-noise fan makes it virtually silent under normal load.

    it being modular makes a big difference, the wires are nice and it comes with one of the new cables that you can plug directly into your GPU instead of plugging three cables in into an adapter
