Extend it's wires... I don't really see why you would need to though. If you need to instantly turn your computer off simply hold down the power button for 6 seconds.
Why cant you wire the switch to the normal front panel button? That would work fine if you do it right.
i would wire it to the front button wires but then the toggle switch would have to be momentary switch or i would have to flick the switch up then down again. But if i wire the switch to the psu and solder the power pin on the motherboard togther it would be that the toggle switch would work how i want it to.
I see. Sounds like a solid plan. Its as simple as soldering wires to the PSU switch and soldering the other ends to your switch. You might as well leave the original PSU switch in place and solder the other switch's wires onto the original ones wire spots so that you can still turn it off with that switch if you need to.
Sounds like a BAD idea. Most motherboards default is that if you keep the motherboard header switch jumped, after x seconds, the mobo will shut back down. You can change that in the bios for some motherboards, but you better hope you never have to reset your bios. This is irrespective of what the power supply is doing. Understand? If you want a instant killswitch, that is easy to do. Pick up an ATX 20 or 24pin block extension cable. Splice a toggle switch into the green ps_on line. This toggle will now be sort of a arming switch. When toggled to on, it will allow the motherboard to power on the power supply. When toggled to off, it will open the ps_on line and instant power off. In order to turn the computer back on, the arming switch must be in the on configuration. This can be done with no voiding of warranties. Another simple method is to open your power supply and wire another switch into the master power switch. Or you could modify your power supply cable cord so that it has a switch. Or you could plug your computer into a socket that already has a light switch. So many possibilities..... Don't solder your motherboard!!!! navig
Sorry if this has already been said: I did this once. In the BIOS there is usually an option called 'Status After Power Failure'. Set that to ON. That way, when you flick the switch on, the system powers up, when you flick it off, it switches off. But, you can also shutdown the system using windows/linux/whatever. Pretty neat.
