**yokeren** · 09-23-2005, 06:12 PM

Im trying to put this new power Supply in my Dell Optiplex GX260. http://www.cartft.com/support/doku/...-ATX-manual.pdf
(for use in car) The problem is that it needs a M/B on/off switch. I think i might have to find to wires from the control panel or? Can somebody help me here?

so connect the jumper on the M1-ATX to where the power switch used to go

hmmmm, I just found out that the power connector on the optiplex, the wiring is different from that of a normal 20 pin power connector, are you aware of that?? I wasnt.

so use a multimeter, figure out the pinout, and make an adapter

Yes.. There is an extra 12v for the MB..and it is a double 12v-dont know why!! We have to make an adapter.
The biggest problem is how to make a plug so we can take the pc out and use it normal-for updating aso.. Did you think about that?? Now I use an inverter so i can still connect it to "normal" power in my house. So here we have another problem...
