how many psu does r9 280x needs?

jokerxD · May 10, 2014

So i dont knownhow many psu does this card need.

Btw heres my specs.

Fx 8320
Gigabyte ga 970a ds3p
Kingston hyper x 8gb 1600mhz
Sapphire R9 280x 3gb Vapor x.

This is the psu that they recommended.
Thermaltake Lp 700W

I read some threads about thernaltake and sthey say its a bad brand.

Can you please suggest some psu?

I recommend Antec, Corsair, Seasonic, PCP&C, & XFX branded PSU's. I would recommend at least 500w minimum for the R9 280x with those brands. I also recommend that the PSU is at least 80 Plus Bronze Certified. That means it is usually built pretty good and is pretty efficient. If you plan on OC'ing the FX 8320 than I would recommend at least 550w-650w PSU to allow you more power for OC'ing.

The 280x requires 550w and 30 amps

CTurbo :

Watts aren't always the be all end all. Here is the Corsair CX 500w PSU with 38A on the 12v rail.

CORSAIR CX series CX500 500W ATX12V v2.3 80 PLUS BRONZE Certified Active PFC Power Supply

Usually the most important value is the Amps on the 12v rail(s), so 30 Amps would be the most concern for that GPU.

I agree. That's why I included amps and didn't just answer with watts. I always like to stay under both minimum requirements though.

Yeah I do also, just showing an example of a good 500w PSU meeting the GPU requirements

Thanks for answers. But i dont understand those amps thingy. Can you just suggest a PSU?

CTurbo · May 10, 2014

Any 550-650w 80+ psu by Antec, XFX, or Seasonic

This is currently the cheapest one I would recommend

There seems to be no available XFX Antec and Seasonic. Only Corsair, Cougar, Thermaltake. Any specific one with these?

lunyone · May 10, 2014

Corsair CX500w is the lowest I would go. You would be better off with at least the CX 600w PSU, but the 500w version would be fine.

Get the Corsair CX600.
