Which PSU is better ?
Hello people, I have 2 400W PSU's at home. One that I'm using it ATM, and another that is staying home. :)
So how can I see which one is more powerfull or better ?
If this picture means something to you'll, here is. :)

As I understand it, most current PC components take power from the 12 volt rail and this PSU appears to have little power on that rail--only about 132 watts (11 amps x 12 volts).
It can supply quite a lot of power on the 5 volt rail, but that isn't where it's likely to be needed.
And I don't know the brand or quality, so it may be horrible or fantastic, regardless of power output.
So, not impressive.
What about the other one?

My opinion:
11 amps on the +12V rail is an indication of a poor "400W" PSU.
For example, this one:

(Antec Neo Eco 400C) is rated at 30A at +12V. It's not a super high end unit.
There are two considerations about PSUs. One is whether one can supply enough current to run your system. The second one is reliability. If a poor PSU fails, it can destroy other components (motherboard, CPU, RAM graphics card). A cheap PSU could become very expensive.
