CORRECTI found this document not only helpfull but correct. I have a DELL PS-5201-7D that I am bastardizing to keep my get the newspaper out! ;)APPROVED
ERROR FIXEDThis connector was used by Dell on Pentium II and Pentium III systems. The connector on the power supplies used in Dell Socket 478 Pentium 4 systems is standard ATX-12v. In the on-line document, to the present is incorrect and misleading... Ben APPROVED

2009-02-17 01:08:56rev. 2INCORRECTNot all PIII systems have this wiring. For example, Dell Optiplex GX-150 PSU doesn't have this wiring. However, an older Dell OSU marked as modell HP-145SNH has such a wiring (probably that's why I found on the Internet that some Dell's would work with a HP PSU ;) ). Also found that the pinout is CORRECT for a Dell Optiplex GX-110 PSU but with a notable exception: NO -5V present (white wire).APPROVED

2009-09-24 19:39:17rev. 4CORRECTThis pinout information was 100% correct for the power supply from an older Dell Dimension XPS R450 with a Pentium II processor. Some newer Dell systems that still use this pinout for the power supply connector do not have a -5V output.APPROVED

2010-09-05 01:15:21rev. 5CORRECTI have this same wiring scheme from a PSU out of a Dell OptiPlex GX1. However instead of a blank key, I have a brown wire. I have no idea what the proper voltage of that rail should be, as the PSU in question is dead. I'm re-wiring another PSU from standard ATX to replace it. Would be helpful to know what that brown rail is. For now leaving it disconnected since I'm replacing the GX1 MOBO with a GX110 MOBO and the GX110 PSUs all have a blank key.APPROVED
