Does anyone know what two wires I jump together with a paperclip on a powersupply to make it work by itself are?

To make your ATX PS work without connecting it to mobo, you have to short(connect) the power-on wire (usually colored green) with power-ok wire (usually colored gray).

green to black i belive as said above
