Corsair RM Series RM850X 2021 850W Power Supply

Very good Corsair PSU. Full modular helps a lot, cable routing is a little harder considering some of the cables have a very hard rubberized section close to their end and that makes it difficult to maneuver around tight spaces on a smaller case. So far, happy with the purchase. Very good Corsair PSU.

Plenty of power for future upgrades, and fully modular which makes building and cable management so much easier.
Only con I can think of is the heat shrink tube on some of the cables make them quite stiff and a tad harder to work with, but still not a problem . Plenty of power for future upgrades, and fully modular which makes building and cable management so much easier.

I don't know if it's just because it's been a while since I upgraded, (from an EVGA SuperNOVA 80 Plus Gold 650W PSU purchased late 2016,) but this thing is *quiet*. If it wasn't for the lights and case fans I'd be worried my PC wasn't turning on. Other than that it looks good, has a solid build quality, and does everything it's supposed to. Cables are no more or less fiddly than any other PSU; I managed to wrangle everything in a mini-ITX case so I'm happy.

850W is plenty for all but the crazy systems.
Plenty of cables and 16pin GPU cables are available for the new 40 series cards should you want fully matching cables.
I expect this supply will alst as long as my last corsair (550W when that was plenty) which is now powering another system.
Cables are flat ribbons instead of sheathed individual wires. Depending on your wire management needs it may help or hinder. 850W is plenty for all but the crazy systems.

I upgraded from an RM750 because of my GPU upgrade, and since that PSU treated me so well, it would've been weird to divert in brands. Corsair PSU's are brilliant.

Great product.
Is modular which has allowed more versatility in my case and overall tidiness.
Comes with cable ties which was very helpful and just overall good power supply with more than enough watts for all my parts Great product.

Great PSU with silent operation. The cables are well braided but is a bit large. Great PSU with silent operation. The cables are well braided but is a bit large.
