[SOLVED] PSU for 3080

[Sonny1989]

Hi im using Corsair RM650. Is it enough for rtx 3080?
My specs are:
I7 4790k (not ocerclocked)
4x4gb RAM
Asrock z97 extreme4
Phanteks PH-TC14PE cooling
Pioneer blu ray
Inwin GRone case
Ive read somewhere that it might be enough and when i do the math it seems like it may be true. Thanks for your replies

Looks like you should be OK.

Overall the 3080 is right at the absolute edge for an Intel 4c/8t CPU with a 650W PSU.

The Corsair RM650 W is a good unit but barely adequate and will suffice however it may let you down if you intend to Overclock or need to expand your system. Best is a PSU with 20% headroom above MIN.

Depends on how old that PSU is. Normally I would say that's a solid unit, but if it's as old as your 4790K is (which would place your system about 2014 - 2015) that would need a replacement to be able to power the new RTX 3XXX series. The reason being is that PSUs do have a limited lifespan and should be replaced every 4 - 5 years or so because the capacitors wear out over time and over a certain number of power cycles.

And I do say this because I recently had to replace a 7 year old Seasonic X with a new Corsair RM750X so even the best PSUs ultimately need to be replaced over time.
