I have an Antec 480w TruePower 2.0 ATX Power supply. I built a new system which consist of the following:
Antec P180 Case
Asus A8V mobo
Athlon 64 X2 4200+
Crucial 512mb DDR400 (2x)
ATI Radeion 9800SE AGP Graphics
WD 80g SATA
Got everything in place. Double checked all my connections. Pressed the power button on front of the case and nothing happens. I double checked the wires going from the case front panel to the mobo and all are correct. I tested the power switch for ohms and it works fine. I used my power supply tester and tested the ps. All voltages pass except for the -5v. Anyone have any ideas why the system will not start and also explain what the -5v is used for.
