This is the Dell plug. I turned it around from the picture on Dell’s Website. |
This is the standard
ATX connector from the same direction as the Dell connector to the left. |

It’s from the XPS ‘B’ series. The colors might not be right, but the wire placement should be. This is looking at the plug from the wire side, like the ATX connector to the right. |

* Pin 5 — PWRGOOD is a status signal
generated by the power supply to notify the system that the DC operating
voltages are within the ranges required for proper system operation. |

** Pin 11 — PSON# is activated by
pressing and releasing the power button while the power supply is in standby
state. Activating PSON# connects the power supply’s PSON# input to ground,
thereby switching the power supply to full-on condition. |

Here is a shot of the tab you’ll need to press to get the wires out of the plastic housing with the metal terminals intact. You’ll need to reach in from the motherboard side of the plug, along the terminal, with something very thin (maybe a piece of wire), press the tab down, and pull out the wire and the terminal from the back of the plug. The terminals just slip into the slot without depressing the tab. I tried to remove one of these little buggers, and discovered there are two of those tabs on each one. I couldn’t get them out of the housing.
I suppose you’d have to remove all the terminals first, and put them in the new holes. It’s cheaper than buying a new power supply unless you let the magic smoke out of your motherboard. I don’t think the 3.3v Dell connector’s terminals will fit in the ATX housing. The fittings for the 3.3v plug have proven quite elusive. They are standard AT power connectors, but I haven’t been able to find any. If you find some, tell me where.
This is a shot of the right side of a standard ATX plug, as if you’d rotated the diagram counterclockwise. You can see some holes have two wires in them. The orange wires are 3.3v.
This is a shot of the left side of the ATX plug, as if you’d rotated the diagram clockwise.
