Corsair RM650x

Currently using this 650W PSU and plan to swap my 1080TI with a 3080
Will it be enough? Really don't feel like swapping it for a new one

PC includes 2x HDD, 2x SSD and 4 fans total (2 intake and 2 on rad).

I know it's a push, but 375W max for the 3080 and I can't see the rest of my PC using over 250W. The PSU has 2x 8pin connectors so must have been made with 375W graphics cards in mind

Was that video made before the Ampere specs were released? Was wondering myself whether a 650x would be okay for 3070, sounds promising!

I've got a 650W PSU and plan to buy a 3080. But at this point I think we need to wait for reviews and see what the max draw compared to the 2080Ti, which runs on a 650W unit.

The way I see it, both the 3080 and 3090 use the same connector so it's highly unlikely the 3080 will max out the power draw

True but it could be working at 100% with a 10900k and other stuff, depends on system spec.

It's always better to have some headroom, and psu don't work best maxed out.

The video a few posts up shows a 10900k and 2080TI maxed out and it never goes above 425W.
I don't have something as power hungry as a 10900k so it's put my mind at ease

3080's power draw/heat output figure is 70W higher than what Nvidia has for 2080 Ti.
(so long for improved architecture in energy efficiency...)
