I was looking for a new PSU and found this, $20 cheaper than anywhere else from what I could see. Not a bad deal with delivery included… But they have a stupid credit card surcharge
CORSAIR RM650x series fully modular power supplies are built with the highest quality components to deliver 80 PLUS Gold efficient power to your PC, with virtually silent operation
Yeah it'd run a 3080 fine, especially considering undervolting these cards might be the go anyway.
I'd probably opt for the 750W because it's only about $30 more and would likely run a lot quieter if that's your thing. Once the RMx get above about 90% load the fan has to start working a lot harder, hence more noise.
Myself I regret only getting a 550W Corsair TXM. Runs my OCed 8600k/1080ti fine but now it's put me in a position where I need to upgrade for a 3080. Just some thoughts for people to consider.
I went with the Corsair SF750 Platinum 80+ model which Amazon had going for $240 a couple of weeks ago (lowest price I could find at the time). I would've probably gone with this one instead if I saw this earlier but I like some of the extra perks you get in going with the Platinum such as the SFX to ATX adapter and sleeved cables. Plus I always like the idea of having extra headroom in the watt department as it means I can hold on to it longer in the future.
I just got the rm750x for $199 from scorptec
not even good enough to run a 3080 haha
