Why don't you tell us what make and model PSU it is?

If it is junk, you need to return it for a refund or credit
towards a better PSU and not run the system until then, if
possible, so you don't risk damaging other parts.


OKIA 450W ATX

Yes- I am thinking of trying to upgrade.

Duke

That PSU is overrated junk, it could be the problem or the
failure of the previous one could have caused damage
(another reason to beware of low end PSU). The only way to
be sure is if you get a legit upgrade, known working PSU
with high, true 12V rail current capability.

A supply in current limiting has effectively shut itself down to

Which is one of so many reasons why loads do not harm a supply. An
ability to switchwattage to loads (as described) is limited. A 400
watt supply cannot transfer 200 watts to one voltage as implied.
Supplies are selected on current for each voltage. Overall wattage is
only a ballpark number that does not answer the OP's question.
Worse, 500 watts when marketed to computer assemblers (typically with
no electrical knowledge) is also the 350 watt supply defined by
professional computer manufacturers. A second reason why determining
a supply from its overall wattage number is unreliable. But again I
post this fact that is largely unknown to many computer assemblers.

Only way to know a sufficient supply is to load it up and measure
actual voltages with a meter. In the OP's case, he has no idea if his
supply is sufficient until making those multimeter measurements under
maximum computer loading. That wattage number varies too much for too
many reasons to answer his questions.
