Dual power buttons?

[OddsCrazyStuff]

I was just wondering if its possible to split the 2-pin signal from the motherboard (with a cable), so I can use 2 power buttons?

 

Why do I want to do that?

I want to have an external power button, since the case dont sit right next to me.

 

Its useful during overclocking sections, where you might need to turn the PC on and off several times in a row.

The problem is, that I dont have any PCI slots left.

The power button just shortens the two contacts as long as you press it.

Wiring up two of them in parallel is no problem. For very long cables (>10 m) you should not use the thinnest one you can finde as the resistance gets to high.

I was not sure, so I asked before I did something stupid with a high end motherboard.

Wire size doesn't matter regardless of distance (excluding a preposterous 10k foot cable).

The level of power being carried is on the order of uA, MAYBE a mA or two. Any gauge of wire you can work with by hand will be sufficient for this.

A twisted pair of CAT5 wires work nicely. All you need to do is connect them in parallel to the existing connection, and run them to a normally open momentary switch.

As long as you use passive components you are save as you can't feed to much power into the MoBo.

Also the detection circuit is designed to operate when the both pinns are shortened.

It's not about the cable can't handle it, it's about the maximal resistance the detection circuit considers to be a shot circuit.

As it is not standardised by the ATX specifiaction I don't have the data I need to calculate the actual minimum diameter. So I use my empirical knowledge and try to give a save advise.

 

But yes it will probably work with thinn and long cables.
