the trupower is the better psu. it is a more advanced design, 100% of power is available on the 12v and all other voltages are regulated from the 12v. It also has lower ripple/noise and actually passes crossload tests, unlike the HCG. read some reviews. Having said that the trupower normally costs more. if its the same price, go for the trupower. And the trupower is semi-modular which makes your case tidiness a bit easier to deal with.
