The Thermaltake Toughpower XT 750W is a great power supply let down only by its failure to meet its claimed 80 Plus Bronze certification following the OCC testing methodology. The efficiency is still very good and the only thing it can influence at the end of the day is the electricity bill. The DC quality is on a par with most power supplies in this class which makes the Thermaltake Toughpower XT 750W more than capable of running any dual graphics cards configuration in SLI or Crossfire.
