new psu no boot??

  1. hi. im running a new 450 watt hercules psu. the system im trying to power up specs are:

    1.2 amd athlon
    1x128mb sdram
    100gb maxtor 7200
    10gb seagate 5400
    dvd rw drive
    dvd rom drive
    floppy disk drive
    evga geforce fx5200 128mb
    pci network card
    pci modem
    pci sound card
    msi-6330v2 motherboard(made for gateway oem)

    the new power supply one turns the power led on. i see no sign of it trying to turn on the processor. the old power supply works fine. what i noticed is the old power supply mombo connecter has all 20 pins. the new one i bought only has 19. but the new one i have has a connecter for a p4 machine. is this where that one pin went? do you think the missing pin is because its meant for a p4? so the missing pin is to start up the processor? i have a picture of the mombo connecters. when the missing psu pin goes
    is that pin for the processor? i have no clue. its missing from the power supply connector to the mombo. not missing on the mombo. is there a way i can fix this? any help would be greatly apreciated. thanks.

    oh yeah. and what would be the minimum wattage psu for my setup? thanks
