gtx 580 with 500w psu?

jimbob mc jimbob · Feb 28, 2014

Hello, I am upgrading my 550 ti to a 580, i wanted to konw if my evga 500w bronze rated psu is enough. i wont be overclocking any parts and my build without the gpu is only using 133 watts

Making arbitrary assumptions about your system, I got 461W from the PSU calculator at http://www.extreme.outervision.com/PSUEngine without any capacitor aging. So, I'd say the answer is "Probably, but you'll be running it hard." It's probably okay temporarily, but I'd have an eye on a more powerful replacement around 600W-650W.

Should work fine.

this is temporary yes, im getting an 650 watt soon any suggestions under £70

Can you find XFX for that price? All of theirs are made by Seasonic.

there is a 650w 80 plus rated for £60 but is the corsair cx 600watt good? i can get one of them for £49

Nvidia rates the GTX 580 as a 244W card maxed out (20.3 amp @ +12V) and recommends a 600W PSU. http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-580/specifications

It'll probably work, but may cause some issues when maxed out if the PSU's +12V rail can't maintain a steady 12 volts at 80% efficiency. Does your Evga have a 6 and 8 pin PCIe aux connector?

No, the Corsair CX is not good. It was made with some inferior Samxon capacitors that don't age well because they can't take heat. Go with the XFX.
