How do you guys have your pc power switch set up?

From my site:

"A capacitor's discharged state is shorted. When you apply power to the unit,
the cap acts as a short between the pins, activating the power supply.

With 5V flowing through the cap, it's shorted state becomes an open state,
allowing the board to boot normally.

When you power down the unit, the capacitor will discharge, and resume its shorted
state, allowing it to do this the next time you power up."

I've done this several times now with no problems.

Yes.... I understood the theory.... The thing is it will only work on older hardware, with effectively higher trigger current. The newer mobo's will take exception to it an think that the switch is constantly pressed. Thus enabling their power off function or standby function after the cap is fully charged. Unless there's an option to shut that off in the bios....... I guess that a larger electro cap might (I say might) solve that on newer mobo's.

I won't have chance to test cap sizes out for about a week.... I'm off to the in-laws today  :banghead: :banghead: :(

I haven't had the opportunity to test it on a new motherboard.  Logic dictates that you'd want a smaller cap, not a larger one.  You want it to short just for a moment, then open.
