My spare PC is in an AT case. It's currently powered by a 200w AT
power supply.

The motherboard has AT and ATX connectors. The mobo is an Epox
EP-58 MVP3C-M and has power connectors for both AT and ATX

I'm taking out the generic AT 200w power supply as it's getting old
and I have a new 400w ATX power supply to put in.

The AT PSU has a power cord which runs to a button on the front of
the case.

The ATX PSU does not have a power cord with a button attached to it.

I've noticed the mobo has a 2 pin connector labelled 'POWER-ON'.

After installing the new ATX PSU, is it a case of buying a power
button with two wires that go to the 2 pin 'POWER-ON' connector?

If so, I'm not sure which pin will be positive and which will be
negative and I'm not sure my mobo manual tells me...

I suppose that electronics shops would stock these buttons.

I'm from downunder, if that helps with PC component location advice.

Thanks heaps


perhaps you can recycle the unused "Turbo" button......

That would work except that usually that's a latching button, though
the latch mechanism may be removable. Could use the reset button as
well but then of course you lose the reset function.

Yeah, but the ATX supply doesn't really seem to mind if you hold the button
down for a bit when cycling it on or off (on all the ones I have, you must
hold the button down for a few seconds to turn off, but mostly 'power off'
is under software control, anyway). I expect the OP could use the original
power switch from the AT supply--or the turbo button--as long as he 'cycled'
it instead of simply turning it on or off.
