Windows Forum / Windows XP / Customization / May 2008A 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 ?

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.  SignatureShenan Stanley MS-MVP -- How To Ask Questions The Smart Way http://www.catb.org/~esr/faqs/smart-questions.html >> It's about a power supply.

Therefore, check with a meter if the load is a lot less than a basic PC. > Hi everyone. > [quoted text clipped - 11 lines] > > Crest > 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 Crest >> You ground the PS_ON line (usually a green wire) >> [quoted text clipped - 7 lines] > > Crest 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. |
