Question about PSU for r9 280x

BooDal · Feb 26, 2015

Hello,

I would like to know if the current PSU on my build will be enough to run a r9 280x. For example, in Sapphire web site they recommend a 750W PSU for the dual x model.

My build:

i5-4460
ASRock H97 Pro4
Seasonic S12G 550W

I don't plan to overclock, but if I do, I'll only overclock the GPU (not aggressive overclock though).

Thank you.

The PSU you have right now is more than enough.

Well, more than enough is exaggerating. 280's are power hungry cards. 550-600W minimum.

Op, you'll be fine just push it too much with overclocking.

When they say 750W they're covering themselves in case someone's PSU is as crap as this http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story&reid=324

Your PSU is excellent quality and as said above, is absolutely fine, enjoy your new GPU

Yes it should be fine. Just don't run Furmark as voltage requirements can spike on the 280X when you do driving the card up to using a full 300 watts. The Seasonic can handle it.

My system is running off a 750w PSU, and everything is overclocked including my crossfire 7970(r9 280x)+7950(r9 280). See sig. The recommended power from the manufacturer is over exaggerated. OP you will be fine.

Thank you all for the fast reply. Just wanted to be sure that's all.

The 7970 didn't have the power draw bug the 280X has. Furmark is bad for any GPU and both Nvidia and AMD classify it as a heat virus but if the card has the potential it's only a badly written driver away from pulling max voltage in demanding games.

I thought the r9 280x was just a re branded 7970ghz edition. Why would they be different?

They are very similar but the TDP is tweaked.
