    #11, yes P=IxV, but the power ratings in the table were obviously taken from manufacturers' data rather than actual measurements, which is why when any power rating for any of the positive voltages is divided by that voltage, the quotient exactly equals an integer. That would not be a problem if all manufacturers applied identical standards to their specifications, but many computer users have learned that this isn't the case.

    Perhaps you could include a Q-Tec PSU in the next review? They retail here in Sweden at about 60% of the price of corresponding Enermax and other high quality units, so assuming they aren't totally lousy they're very cheap.

    I agree with #15. Definitely take a look at the PC Power and Cooling 400w Silencer PSU. I own two of these units and they're very high quality with reasonably low noise.

    Enlight power supplies are always being excluded from these PSU comparsions. I have a Enlight 360W PSU and it's very stable and very quiet. Test some Enlight PSUs!

    I appreciated the comments concerning AMD users, but what I really need is some sort of guidance on AMD processor speed vs combined power or 3.3V rail current for upgrading older systems. Many older cases have limited power supplies and I'm trying to figure out the fastest processor I can install and still have reliable operation. Example: A 300 watt supply with 25A of 3.3V can only support up to a Athlon 1600+ on an ECS K7S5A Pro or a 350 watt with a combined power of 200W can support up to 2200+. Oh, and forget that old 250 watt power supply altogether. I need something like that... yeah, I know: your mileage may vary, void where prohibited by law, no watts were endangered in the making of this article.....:-)

    Next time you guys might want to check out the PC P&C Silencer 400. It's built just as heavily as the Turbo Cool but with a quieter fan.

    Hey guys, im sure 1 or 2 of you resistorheads are an ee or will soon be one.. ripple and noise are only part of a good pwr supply.. we need the facts... how many watts do these power supplies really put out. how do they respond with a big load.. will they take an overload.. how well are they protected...thats what i wanna read about

    WOW - excellent review. I'm getting a zalman for my silent box.

    Nice to see you guys pumping out articles quickly again! Thanks!

    hey just wondering the allied A400ATX hows that compare with the B400ATX thats offered on newegg? any differences?

    #10, doesnt P=IV? The Power and Voltage measurements were given.
