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

Corsair wins again. EVGA’s same line of PSU arrived DOA. Never had that issue yet with Corsair thankfully. Reliable quality so far. If you’re going to be doing any overclocking with higher end products, you’re going to want to get a PSU like this for stable current draw. Worth the money, you get what you pay for.

Absurd value, amazing performance, ridiculous warranty. More in-depth reviews by johnnyguru and others go in to the details pretty well, but the conclusion is straightforward; this is the power supply you should buy, period.

Runs quiet on full load. Great value for money, consistent Corsair build quality. Easy install and comes with a bag to store all the extra cables, of which there are many.

The Power Supply Unit itself is goo... really good in fact, but the cables provided are terrible. Imagine going to a BMW dealership and buying a brand new 2021 BMW M760, and when they give it to you it has 4 spare tires on it instead of BMWs stock rims, thats this PSU, great power supply, bad cables. Corsair has a premium individually sleeved PSU cables pro kit that they should sell with every power supply instead of these garbage stock cables. Now I have to buy the pro kit and delay my build another 2-3 days.

I had to connected PS Fan to internal 5 Volt source...and now it is OK.

Received it a week ago, built my whole mining rig to find out it couldnt even power my motherboard, instead it did the opposite, killing my motherboard any having me to purchase another. Im just thankful it burned the motherboard and not the rtx 3060 ti.

Low noise level. Fully modular. easy to install and fits perfectly in the Corsair 4000d airflow case

Works great

Great PSU! Runs silent on idle. Very happy with my purchase. Only thing is that the PCI-e connectors are very thick and hard to bend when plugging it into the GPU.

Everything about this PSU is great except the cables. Dont get me wrong the cables look great (all black cables are wonderful) but the cables are impossible to bend into position in tight spaces and the connectors between cables heads (the part that keeps the 4+4/8-pin cpu headers and the 6+2/8-pin pcie headers together) are pretty flimsy and dont really stay together when trying to plug the cables into the motherboard. But I guess thats the price you pay for full modularity
