Hello, I want to buy a new graphic card and after long search I decided on r9 280 (x version is out of my budget). I've been wondering between Sapphire Dual-X and Gigabyte Windforce, however;
Gigabyte WindForce 3X lists its requirements as 600watt and 42 Amps.
Sapphire Dual-X and many others list only 500watt.

Besides the fact that I can't find the required Amp ratings for the Sapphire, I am still not sure how Amps on rails are supposed to be calculated.
My PSU is OCZ Stealth X Stream 2 (600 watt), the same as here:

The label on my PSU:
Is my PSU enough to run any of these cards?
