The lemon-market in PC power supplies has now officially become bad enough that no-name generic "500W" PSUs may actually barely even be able to deliver 250 watts. A realistic constant rating for these units is more like 200 watts. So the capacity inflation factor's hit 2.5, and it's still rising.
Our generic 500 W power supply died when we tried pulling 275 W from it, so the maximum amount of power we could extract was 250 W – half the labeled amount!
On the front of the box it says "Triple Rails for +12V" and then goes on to say 'Intel ATX 12V Version 2.0 & EPS 12V Version 2.1". It turns out from our investigation that the above power supplies do not meet the ATX12V or EPS12V standards as the packaging claims.
