How to power up a compaq 243890-001 power supply without the the motherboard? Its not green to ground
Remove Power Supply
1 . Shut down your computer and unplug the power cord and all cables connected to the system.
2 . Open the computer case and disconnect all power connectors from the motherboard, drives, cards and fans.
3 . Remove the four screws that secure the power supply to the case. These screws are located on the back of the computer case, at each corner of the power supply.
Wire and Start Power Supply
1 . Switch the power supply to the "Off" (sometimes "O") setting.
2 . Insert the end of one wire from a single pole, single throw (SPST) switch into the green wire of the ATX power connector (the largest power supply connector).
3 . Insert the end of the other wire from the SPST switch into the black wire of the ATX power connector. If your power supply has two black wires, connect the SPST to the black wire directly beside the green wire.
4 . Wrap electrical tape around the ATX power connector and wires from the SPST switch to hold them in place. Make sure there is no exposed copper or silver wire from the SPST switch wires.
5 . Turn the SPST switch to the "Off" position, if not already set. Plug the power supply into the wall outlet and switch it to the "On" (sometimes "I")setting.
6 . Connect any other computer components that you wish to operate without the motherboard, such as fans, drives or cards. Turn the SPST to the "On" setting to activate the power supply.
Hope the above information will be helpful to you.
