Bypassing ATX power on button?

[CNS]

Hi all,
I suspect a faulty power on switch in an ATX case, is it safe to power the system on by shorting the two pins (by putting a jumper on them) on the mobo where the power button would normally go?

thanks

Sure is, do it all the time. Just make sure those are the only two pins you short out.

swop the start button , with the reset button leads , and then press reset to start it up .

if it works u can pick a switch up from a scrap case or from radio shack or wherever.

Thanks people, I knew it all the time. Never hurts to have confirmation.

Just remember that atx power buttons are momentary contact..leaving the jumper on the pins would have the same effect as holding in the power button

Excellent link!

Just only... personally I wouldn't use paper clip for shorting those pins... You see, if power supply is gone bad (mostly it happens because of standby module failure). And, as result, sometimes all the AC voltage can come instead of +5V SB, and to this "Power-ON" pin as well... So, you can get shocked...

Quite 'shocking' my now Canadian friend definately worth a mention though !

indeed a good link, but what does using that method to test a psu have to do with shorting out motherboard pins to bypass a power on button?

Huh ? what you talkin' about willis ...

Oh I see .... - helps if you read ALL of the question ... I was helping him test his psu - he-he- maybe he might want to know that as well

as answered in the posts above YES to shorting the pins together momentalily ,,,NO to a jumper , because that would be the same as holding the power switch on.

use the wires from your reset switch to test it out , then buy a switch from radio-shaft
