Corsair RMX Series, RM850x, 850 Watt, 80+ Gold Certified, Fully Modular Power Supply (Low Noise, Zero RPM Fan Mode, 105°C Capacitors, Fully Modular Cables, Compact Size) Black

Super quiet and very reliable. They provide a bag for unused power cables and provide any power cable you can think off in black cables with black braided sleeves.

its been nearly three years and it has yet to fail. <3

Rock solid power supply with minimal heat generated and super quiet. I use it in a 5-card mining rig and the PSU generates less heat and noise than even 1 GPU. Modular so I can connect cables when I need them. The only complaint is that it has only 5 PCIe 8-pin cables, not 6. I would buy this again.

I bought a 850w corsair 11 years ago and it finally crapped out. I bought this 850w replacement because I trust the name and because it lasted so long. turning it on and off every day equals about 4000 plus cycles. Being a heavy gamer running 2 video cards with everything overclocked I wanted something that would last and it did. With this new unit, its nice having a modular design so I only plug in the cables that I need instead of having to hide the entire load in my box restricting airflow and being a general pain when you need to add something having to work around all those extra cables that were supplied at the time. This was a great buy. Thank you Corsair

Fantastic power system. Cant recommend highly enough. Near silent power system.

Non module rules!

super quite even under full load running a couple closed loops, a 6700k overclocked and a pair of R9 390xs.

When I bought this it was super cheap for some reason. I thought it was sketchy but bought it anyway. If you can find this on sale buy it. I got mine for around 90 bucks. It was an incredible price at the time. Its not junkie or sketchy its really good tbh. Buy it!

Arrived with defective 12 volt rail. Cost me more to diagnose and replace than its cost. Shabby QC.

The main unit seems well-built -- fans are good quality. The power cord has 14ga conductors. The problem comes with the modular cables. If youre building in a full-tower case (my case is 20 inches tall), few of the cables will be long enough to run through the cable-management cavity (cleanly) and reach their destination. Youll have to run them across the motherboard out in the open. The worst trouble spot is putting an optical drive in the top slot! And if you want a 2nd device powered there, you have to deal with the next plug down being too far down, or mess with power splitters etc. This may all be fine if your PSU mounts in the top, but most are in the basement of newer cases. Corsair doesnt sell longer ones, or extensions.
