Price Per the Watt:

Power Supply Thermaltake Toughpower XT 750W Cable Management at $114.99 = $0.15/Watt (01-2010)


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. The S.P.Tindicator is a nice feature and could help to fault find but in all honesty high end power supplies are built to such an high standard these days that problems rarely occur. The same could be said for the FanDelayCool feature, it will no doubt extend the life of the power supply but with mean time before failure figures of 100,000 hours or 11 years commonly quoted, is the feature really that useful? The Thermaltake Toughpower XT 750W is still worthy of consideration for any high end build requiring 750 watts of power but due to its failure to maintain the levels of efficiency required by its claimed 80 Plus Bronze certification following the OCC Testing Methodology it's gold award for DC quality will have to be an overall Silver.
