Recently I bought a new Gigabyte GTX 580 which is factory overclocked to replace my old 5870 . My rig is core i7 870 ( 4.00GHz OC ) , 8 Gig ram, 2 HDD , 1 optical Drive and 7 fans. I never encounter any power related issue so far with my Corsair 550 watt. But now i can see in nvidias site that to smoothly run GTX 580 , i need a minimum of 600W PSU !! I was wondering if i can run this card with my current PSU , that is corsair vx 550 watt ( (+12v @ 41amp) without any trouble ? Please im in a tight budget so i really can use some helpful information . Many sites tell that A gtx 580 can be ran on machine with 550 watt. Hence im confused whether i should buy a new PSU or can keep using my corsair vx 550 ??

yeah i would recommend at least a decent 700w psu. my old cheap aprevia 650w psu barely did the job with an x4 965 oc and the gigabyte soc 580 down clocked to stock speeds and voltage. i would see the card throttle via MSI afterburner while playing bf3 at max settings. now i have a decent 750 watt and i can keep it at its original OC with original voltage and have my cpu overclocked easily.

Since you already have the video card you can simply test it out yourself,but i would say your PSU should be enugh,the 580 draws less power than your 5870,but since you already have every thing you can easily test it.

580 will draw 250W when slightly OCed. so i dont there you will have a problem. you still will have some left for the CPU.

Don't Listen to anyone else, You'll be fine ocing that GPU, PSU requirements are fairly low, most people have become too stressed over it. the rest of the system wont draw more than 200w you can max that thing out and you'll have room to spare....

Anyone who claims they didn't have enough power clearly didn't have a corsair
