Cap trick wont work to power up atx PS
(1/3) > >>

Hello all. I have recently tried Peale's cap trick to power up my tower and I can't seem to get it working. I used a 10 mf, 50 v electrolytic cap. I came off the "power up" jumper pins and nothing. Next I tried a 22 mf, 50 v electrolytic cap. Still nothing. My mobo is an ASUS A7N8X-X I think. If I touch the wiring(which is about 12 inches in length) together I have coming off of the jumper pins, my tower powers up. So I know I have the right pins. The only thing I could think is to try a lower mf rated cap, but I wanted to consult the pros(that is you guys :P) before I made another trip to radio shack.

BTW My setup is as follows. Wall outlet to tv power to toggle switch to surge protector where everything else plugged into. My tv is hard wired "on" through the control PCB. I can get everything else to come on except the stinking tower. I have been observing this board since I started my cab a year ago. I just wanted to let everyone here know how informative and helpful this site has been to me. You guys are awesome! I appreciate any help u can give. Thank you all and happy thanksgiving!!!

Are you sure the + and - are the right way?

I know you are not supposed to, but I actually tried it both ways.

silly suggestion time.....

have you tried just leaving the wires connected to each other?

some machines will power up and stay powered like that.

also have a nose in the bios of the machine and look for power settings, quite a lot of machines around now have an option of what to do after power failure (or when the machine is first given mains) the board in my cab is set to turn itself on after mains failure.

another thing to look at in the bios is whether you can power the machine from any key on the keyboard, then you could power it up by pressing any key on your control panel or moving your joystick

Have you tried just shorting the "power good" line and ground at the ATX MB power connector?

It should be the green wire.  What I have successfully done in the past was, without cutting through the wires, strip about 1/2" of insulation from the green wire and an adjacent black wire, solder or twist them together, and tape them up well.

The result is a computer that you basically can't turn off....ever.  Not sure if it works on all systems, but it has worked well where I have needed it.
