Dual 12v+ PSU+ GTX 570 question

I've been searching around all day to find out whether or not my power supply can handle a GTX 570.

I'm using this Power Supply and thinking about buying this GPU.

The main problem here is not with the max wattage-- I've searched around and it seems that 630W is enough in itself. However, the card claims that my PSU needs 38 amps on my 12v+ connector, and the power supply I'm using has dual 12v+ connectors with 22 amps a piece. I've read around and understand the basics of dual connectors (that they won't combine and all that jazz), but I don't know EXACTLY how many amps the GTX 570 will draw from a single 12v+ connector-- not sure 22 amps will be enough.

Any help would be greatly appreciated. Thank you!
 
You should be ok with that power supply. You just want to make sure that the card is on it's own rail, while everything else is on the other.

I'm not sure how to do that, can you explain further or direct me somewhere that will explain it?

Thanks,

The Raidmax is a pretty lowend cheap power supply. It probably only has in the 400W range on the 12V rail and I doubt it has 38 amps on the 12V rail, even if its does its probably at Max. The 22 amps rails, all that means, if a rail hits above 22 amps it will trip out. You dont add them together. Will it work, it might. If not you might get to watch a spark/smoke shut down show.

If the PSU ends up NOT working, what would you recommend for under, say $80?

Not a problem. You don't have to go with the one I showed you but it would work fine. The main thing is to go with a good brand that's going to meet your power needs. It's a good idea to go with something that's rated higher than what you need there isn't as much load on the power supply.
