"Do you think you can ever have to large of a power supply inside your case? My personal opinion is no, not when there is a good chance that after one hard drive gets full I will simply add another into the system so I am not forced to take the take the time to reload everything. That is where the power supply that we are reviewing today comes into play, The Tagan ITZ Series 1300 Watt PSU is a real 1300 unit which means that I can load 8 hard drives, a dual core processor and two video cards and it will never break a sweat."
