Specs: Windows XP Home, 1gb
The HP Pavilion 540n uses a modified ATX-1956 power supply. I need to know what the differences are between the ATX-1956D and the HP modified version.

If I'm not mistaken, the old power supply got it's fan power from the motherboard via a 3 pin connector that plugged into the mobo. The new psu's for that model eliminated the 3 pin connector. The psu now has the fan control built into the unit.
