Will this work with a P4 mobo is it just to supply auxillary power? I am trying to avoid buying a new PSU to power Abit IC7G P4 3.2 1 gig Mushkin DDR Radeon 9800 Pro 1 HD 1 CD Burner This will be used for server and Linux Distro testing only I probably can get an older Video Card to stick in Thanks More about : antec pp403x 400w psu 12v connector work waylander July 16, 2006 3:31:20 AM That square 4 pin connector is to power the processor.
