Looking at the long list of power supplies we've reviewed here in the past, there's one brand name that surprisingly hasn't had a chance to cross our test bed yet - Thermaltake. Today however will change all that as the Thermaltake Toughpower 850W power supply has just arrived! I must say I've been excited to test this supply because not only does it offer 850 watts of power, but also offers a modular cable system, silent 140mm fan, great looks, and much more!
