Our European Senior Reviewer Grace evaluates the high end modular Power Supply Unit solution powering her Intel P4 3.73 EE, Asus P5AD2-E premium based test bench. Read along as she determines the flexibilty this unit offers in it's modular construction, and takes a look inside to see what make this unit the powerhouse that it is. "Most users underestimate the necessity of a good, reliable and high quality power supply unit. They usually do not understand that it is the driving force for the whole system and it can affect reliability and stability substantially. An inadequate power supply unit will cause instability of the system at best, it may overload and burn out attached components in the worst case scenario. Hiper (High Performance Group) recently released the Type-R modular blue line HPU-4B580 power supply unit, which is competitively priced and claims to be able to offer everyone what they want and require. Hiper was nice enough to have us take a look at the unit, so we will shortly know if it can stand up to its claims."
