Thermaltake Toughpower 550W Power Supply
 

Thermaltake has raised the bar once again with the newest addition to their power supply family. The Toughpower 550W is all that Thermaltake claims and more. With the well sleeved cabling and ample connections alone, this power supply has become one of my favorites. Add in the extremely tight voltage rails and the Toughpower has earned itself a permanent place in my computer's case.
