Thermaltake Toughpower XT 850W Power Supply Review

The Thermaltake Toughpower XT 850W performed flawlessly from start to finish. The DC voltage load regulation is excellent and the efficiency amongst the highest I have tested and fully deserving of the 80 Plus Bronze certification. This Thermaltake Toughpower XT 850W carries the AMD Game Ready and ATI Crossfire X Technology logos. The only information I can find on AMD Game Ready is a minimum PC specification (Athlon X2 5600, ATI Radeon HD3650, AMD 770 or Nvidia nForce 500 chipset & 2GB DDR2 memory) to meet before it can carry the logo but with the wide variety of different manufacturers producing these parts does this certification really mean anything?.
