CORSAIR RM1000e (2025) Fully Modular Low-Noise ATX Power Supply with 12V-2x6 Cable – ATX 3.1 & PCIe 5.1 Compliant, Cybenetics Gold Efficiency, 105°C-Rated Capacitors, Modern Standby Mode – Black

Amazing power supply includes all cables i could possibly need for my build. the 12v Rail produces constant even power levels that my GPU truly enjoys. Having owned several corsair products in the past I am confident in the build quality of this unit and have yet to have any power issues at all, installation is simple and it did include the screws and zip ties for cable management. this power supply has wonderful performance and provides a great value for the price as one should expect from Corsair.

The CORSAIR RM850e (2025) is everything I wanted in a high-performance PSU. It’s compact, fully modular, and the fan rarely kicks on, and when it does, it's whisper-quiet, exceeded my expectations Installation was smooth, cable management was clean, and the build quality is top-tier It also comes with plenty of cables, if you're looking for performance, silence, and reliability, this PSU delivers grate value

I love these power supplies, I think they are the highest quality for this wattage. They look very nice and fit both builds that I have used these for. The cooling for the unit appears to be efficient and during use is quiet (you notice other components make noise before this PSU). These units run for a long time and work well to power mid tier to high tier parts. Just make sure the power supply has sufficient wattage using a PC wattage calculator available online. I think these are the perfect power supply and would use these in every build.

The best PSU I ever bought. Very sleep look and the performance is perfect for what I need. Very light weight and durable quality. Speed wise it's excellent and extremely quiet. Definitely worth the buy.

Fully modular design — clean build, fewer cables, and tidy cable routing80 Plus Gold / Cybenetics Gold efficiency — meaning lower heat and power wasteSemi-silent 120 mm rifle-bearing fan with zero‑RPM mode under low loads — great balance of cool and quietCompact ATX 3.1 form factor (~140 mm deep) — fits snugly in most mid-tower casesSolid protection suite + 7–10 year warranty — backing Corsair’s reliability claimsThe RM850e is a powerful, efficient, and very capable PSU, ideal for modern builds with high-power components.

This is one of the best power supplies I’ve used. Fully modular design makes cable management a breeze, and it powers my high-performance build with no issues. Runs silently, even under heavy load. Corsair’s quality is unmatched, and this unit proves it. Highly recommended for serious builds.

It's worked well and it is a very good wattage for very good price. It gets pretty hot but the built-in fan works pretty well. It isn't that noisy either.

I'm a PC builder and I can say, I plugged this in and my system came right up. I got the 1000w one because of the graphics card. If you have a high-end gamer graphics card that can do VR, then get at least the 1000watter. If you're running a basic system, you don't need as much power. I pretty much leave my system running 24/7 and it goes in to low power mode. So far, no problems. Great power supply for system builders. Came with all the cables.
