GTX 550Ti and H750P-00 power suppy

Hi,

I just received two GTX 550Ti graphics cards, and I'm concerned about it working with my power supply because I don't know how to read the label properly. I meet all other requirements for these cards.

I have a Dell XPS 700 with a 750W power supply, part number H750P-00. Here are the outputs:

Power Specifications:
+5V --- 16.0A
+5VFP --- 3.0A
+12VA --- 18.0A
+12VB --- 18.0A
+12VC --- 18.0A
+12VD --- 16.0A
-12V --- 0.2A
+3.3V --- 30.0A

The minimum system requirements for the graphics cards are Minimum 400w or greater system power supply (with a minimum 12v current rating of 24A)

Will I be able to use one card? Both cards using SLI? (my computer is SLI ready) ...or time for a new PSU? :) 

Thanks so much in advance!

With 58 amps of 12v power spread across 4 rails and a pair of 6 pin connectors, shouldn't be anything to worry about.

You're so wrong and so unacknowledged.

@ BCIII
Dell XPS is a high end gaming machine, it's quality and materials are better than the standard Dell ones.

Your PSU is fine to drive 2 HD 6950s or 2 GTX 560ti's in CF/SLI. No problem at all.
