The guys over at PC Perspective give Thermaltakes beastly 750W offering a run. If you are in the market for a power supply in the 60~750 watt range, one of the new Thermaltake Toughpower units deserve a close look. The 750W model exhibited very good voltage regulation and stability and was quiet, especially while operating under moderate loads. The overall efficiency is very good and Active PFC, sleeved cables, and a 3-year warranty are added pluses. The Toughpower 750W is notably the best power supply I have ever tested from Themaltake. The specs on the Toughpower's are pretty good, and better than I've seen on their PurePower series. If you're looking for a good PSU for your SLI or Crossfire box, this might be a good one to look at.
