A bit of electricity

Hi everyone.

It's about a power supply. I know it has nothing in commun with the actual forum.
I simply don't know a better forum. None has the trade of this one.
So thanks in advance for your tolerance.

I want to use a power supply and a peripheral both independant of my actual pc.
Since the power supply isn't connected to a motherboard, no electricity is generated.

Someone knows how to simulate the presence of a motherboard with the sole connectors
of the power supply ?


Cordialy,

Crest

There are better forums/newsgroups - they likely do not contain "Microsoft"
in their title. ;-) You could try the "microsoft.public.windowsxp.hardware"
newsgroup - but...

Anyway - you can either get a different power supply (older type that uses a
mechanical button) or figure out the wiring needed to short yours so it
works with a mechanical button. How to do that EXACTLY likely depends on
the particular power supply in question. ;-)

Your best bets will be electronics forums, google searches for schematics,
etc.

comp.sci.electronics

You ground the PS_ON line (usually a green wire)

Note that some PSU's give inaccurate voltages under very light loads.
Therefore, check with a meter if the load is a lot less than a basic PC.

Works like a charm !

Thank you

Yes, you really need to check PSU output underload, e.g. IN the PC and
working. It's the nature of switching supplies. The output without a
load is not reliable at all.
