I'm thinking about getting a GeForce 590 via NewEgg (Getting ready for ArmA 3) but I'm kind of worried that my PSU isn't capable of doing the job. (750w) I've looked at the 590 club and it's members. There's one guy with a 775w PSU.

I've also did a bit of research on came upon a review where its power consumption at peak would only reach up to 491w. But a NewEgg reviewer has also stated that he had a 750w PSU and when his 590 reaches >90% activity, his system will restart.

tl;dr: Will a 750w PSU handle a GeForce 590?

His 750W is probably a piece of junk.

Which Thermaltake model do you have? Even the lowly 750W "TR2" should be enough!

I also need to mention that AnandTech was able to get their test system to pull 536W from the wall with a stock GTX 590. If I factor in 85% efficiency, then that would mean that the system pulled 455.6W from the power supply during that load. So if I add 150W to account for the rest of the system, that brings me to about 605W of power being pulled from the power supply.

AnandTech was also able to get their test system to pull 588W from the wall when it had a GTX 590 "OC" in it (or perhaps it was just overclocked; I didn't read that yet). If I assume 85% efficiency, then that would mean that the system pulled 499.8W from the power supply during that test. If I add 150W to account for the rest of the system (recommended), then I get about 650W.


Edit: Oh yeah, the 750W Toughpower is more than enough. Nice PSU choice! It certainly won't result in a system restart if your GTX 590 is under 90% load.

Aye thanks for the in-depth help. I'll look forward to my 590 coming in the mail.
