if its an at power supply, just plug it in and switch it on, and get +5 
volts from any red wire, and ground from any black wire.  If its an atx 
power supply (newer), find the green wire, cross it with any bla k wire, 
then   get +5 volts from any red wire, and ground from any black 
wire.  THen power up.
