Will my PSU suffice for a 570?

post #1 of 9
Thread Starter 
I'm thinking it won't because of the amperage but it's such a good PSU I don't want to get rid of it.. : /

"550-watt power supply with a minimum of 38 amps on the +12 volt rail"

And I'm on 700w w/ 25a on each rail. Sadface. If I do need one, any recommendations?

It will. You can split the rails by using the default pci-e plugin and then a molex to pci-e convertor to leach off the other line.

Edit: just took a closer look at the specs on the page. You don't even need to do what I said above, it will work fine. I ran my gtx480 on a 620hx with no issue.

That psu has 50amps on the 12v. If a psu has multiple 12v rails, you just add the amps up

GTX 570 only requires 22A anyway so you're good to go or combine the rails.

I don't believe that's true.

Thanks, all! So do I need to do anything special or will just plugging it in as normal work? I only had to ask because the orig PSU for my current rig had the wattage but failed to boot an 8800gt, thus my over kill 700w psu. : )

At least 2 NE product specs say 38a. nvidia.com doesn't say other than wattage
