As hardware manufactures add more and more components to PCs such as multi-core processors, multiple video cards, Physics processors, large RAID arrays, etc the need for a strong power supply becomes more and more important. Now a day's a 500 watt power supply seems to be just enough to squeak by when you reach the midrange-higher end. Thermaltake has answered the call of many enthusiasts with the Toughpower 750w which provides quad +12V rails, Active Power Factor Correction and a high efficiency of up to 85%, and on top of all that it is a modular Power Supply so it won't clutter up the inside of your case.
