A couple of years ago 500W power supplies were considered very high-end but these days ultra high-end gaming PCs use a lot more power. Dual-core and quad-core processors along with a SLI or CrossFire setup of NVIDIA's GeForce 8800 Ultra or ATI's Radeon HD 2900 series can use a lot of power, especially when these components are all heavily overclocked. In this review I'm taking a closer look at the ThermalTake Toughpower 1000W power supply with modular cable management. ThermalTake's Toughpower PSU lineup is available with standard and modular cables with max outputs ranging from 550W to 1500W.
