Tags: Power Supplies Antec Components Last response: July 16, 2006 6:00 AM in Components Share kypumper July 16, 2006 1:02:04 AM I have an Antec 400W model pp-403x laying around it does not have the square 12v connector that many motherboards have. 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. If you don't use it, at best your processor won't perform to spec, at worst you won't be able to POST. pengwin July 16, 2006 6:00:04 AM no way 25 bucks is gonna break ur bank. http://www.newegg.com/Product/Product.asp?Item=N82E1681...
