I ordered some new hardware but I may have overlooked a video card requirement. The video card is a Geforce 470 GTX which has a minimum recommended power supply with +12 Volt current rating of 38 Amps. Now the power supply ratings are 650W/Max with +3.3V@25A, +5V@25A, +12V1@22A, +12V2@22A, +12V3@25A, -12V@0.5A, +5VSB@2.5A outputs. When considering how the card requires 2x 6pin inputs (both 12v/22amps) will I run into a power shortage?

::Edit:: Will the graphic card be able to run??? Or will I need to purchase another unit? ::Edit::

you have 3 x 12v rails with over 60A total, you will be fine.

Ok thanx for the feedback. When I was giving this some thought (volts remain the same whereas amps add up while in series) I wasn't worried, however I couldn't be sure this was correct when applied to a situation concerning graphic cards.

60a x 12v = 720w
pretty sure he doesn't have anywhere near 60 amps on his 650w psu.
