1000W Fully Modular Power Supply, 80+ Gold Certified PSU | ATX 3.1 & PCIe 5.1 Ready | 12V-2x6 Connector | 140mm Low-Noise Fan | 105℃ Japanese Capacitors | Black PSU

The CORSAIR RM850e (2025) is a solid choice for a modern gaming or performance PC build. With 850 watts of power and support for the latest ATX 3.1 and PCIe 5.1 standards, it provides plenty of headroom for powerful components while keeping the setup ready for newer hardware.I really like the fully modular design because you only need to connect the cables your system actually uses. This makes cable management much cleaner and helps improve airflow inside the case, which is especially nice when building a PC with a tempered glass panel.The included 12V-2x6 cable is another useful feature for c

I’ve been building PCs for over a decade, and this is easily one of the most impressive power supplies I’ve used to date. I picked up the CORSAIR RM850e (2025 revision) as part of a rebuild centered around an Intel i9-12900KS and RTX 3090, and I’ve been nothing but impressed so far.Build Quality & Design:The unit itself is solid — heavy in a reassuring way, with a clean black finish and no unnecessary branding or flashy extras. The fully modular design is a huge plus, especially for managing cables in a tight mid-tower. I appreciated that the included cables were all black and flat — easy to r

Very intuitive to install, had every cable I needed (12v high power connector), High quality feeling. Only complaint is slight coil whine, but that’s to be expected with any PSU when under high load. Would recommend to anyone.

High build quality, and the small size makes cable management easy in bigger and smaller cases. The included cables are very nice, and are aesthetically pleasing as oppose to most PSU's. Also very quiet on idle I can't even hear when it turns on under load.

This power supply is a beast. I’ll never have another ps that isn’t modular. I have an old atx case with a frankly ridiculous number of drives in it and this ps isn’t even breathing hard. My last ps was a Corsair 750 and it lasted 12 years in this rig overloaded the whole time. I’ll be dead before this ps is.

Came with more than enough cables, very quiet, and pretty solid

Sleek design, easy setup, low noise, and very good price for the performance you are getting being able to run my 5070ti with no problem as well with my other components.

Great power supply
