Detale,
There are two problems with cheezy PSUs:
-When they go, they tend to take out other components as well.
The best example is the Bestecs used by eMachines and Compaq...50% of the time they fry the motherboard when they fail.
-Even if the PSU appears to be functioning normally, line ripple and variable output can cause innumerable problems- problems you'll go nuts trying to trace because the power supply seems to be OK (i.e., powers up. POSTS, and boots to desktop). You'll suspect everything BUT the real culprit.
Sadly, there is no industry standard for power supplies.
Basically, the maker can claim anything they want.
For instance, a PSU will make more power at low temps...there is nothing to stop the manufacturer from testing his supply at 0ºF and then labeling it as a 500w, even though at realistic temps it falls to say, 300w.
The best source of reliable (and realistic) PSU info is jonnyGURU, IMO.
