Short the 2 pins momentarily that you connect the power button to.
Dont short anything else!

Grounding the green wire on the MB PS connector will also work. Just a quick touch will pop it on.

short the 2 "pwr" pins on the header on the motherboard, go into the bios and in the power options setting in the bios, there should be an option to start the computer using a key board password or using a click of the mouse.
From then on just use you key board or mouse to start the pc.

thats questionable

it will bring the power supply on but the mobo might not particularly enjoy that.

So if the PSU main ATX 24-pin connector is connected to the motherboard, how do you access the pins to short them? the solder points on the back of the board?

Backprobe them from the connector side?

I don't know... still sounds like a bad idea to me....

I had just a short piece of wire with maybe 1/8" stripped off the MB end then just carefully stuck it in the connector briefly. Held the other side to the case.
