Thermaltake ToughPower 550W
 

Today, I'm looking at Thermaltake's yet to be available ToughPower 550W power supply. You might ask what's the big deal? Let's say you already have a PurePower / PowerStation ~500W model. While the amount of Watts may be enough, your new components may require more stable voltages and higher amperage (strength of an electrical current). As the name implies, ToughPower is all about stability.
