Maximum length of 2pin motherboard extension lead

I have one of my two powerswitches in an external radbox and the run of wire is about 6 feet, there is a tiny delay upon flicking it though so I wouldn't think much longer is possible with that low a voltage, the wire just absorbs the current basically

thanks for the quick response, I should be ok then  

Should be, see the little silver plate at the front top left of the box? thats where one of my powerswitches is mounted, it goes through the radbox, through one of the tubes that connects to the rear of the main Pc, and all around there to the powerswitch on the door panel (also modded to be there), its a nice long run and as I said, works just fine  


let me know how it goes man
