Will this PSU run a GTX 570?

[smeg4brainsuk]

Hey all, upgrading my graphics card to a ASUS GTX570 DirectCUII (got a really cheap and means i can upgrade the rest of my system around it later in the year) however i haven't a clue how PSU's work these days.

I have a High Power Plus 750 (http://www.highpowerplus.com/750.htm) so i understand it has the Watts to do the job
It has 4 12v rails so that's fine, i think
But what about the Amp's on the rails? i caught mention of this when browsing these forums and it seems to be fairly important these days (no more buying a fat PSU and having it run everything!)

I have looked here and read the section on PSU's and its taught me a fair bit but i'm still a little lost so any help would be greatly appreciated

The current needed from the 12 V rail is for the system as a whole, for the most part all modern PSUs have their connectors distributed so you don't need to worry about if you have a single rail or multiple rails. Your PSU has 650 W(~54A) available from its 12 V rail which is more than enough for a single 570. The rule about needing to check both wattage and current available is more for smaller lower end units where you may have a 500W unit that only has 300 W available from its 12 V rail which won't support a big card.

Here is something that might help clear up some of your confusion with the multiple rails issue.

A 700w psu is enough to power just about any single card system, with the exception of the 590, and the HD6990. The bigger units are more needed with dual, triple, or quad graphics card systems.

Thank you very much

By the way if you asking if a psu will run your parts, maybe you should actually list the parts your running? Just a thought....
