Intel 975XBX power connections

[us3rnotfound]

I wanted to see if anyone here knew which power connectors to plug in to the 975XBX. It includes a 2x12, 2x4, and 1x4. Do I just plug in all three?

Yes, all three.

The 24 pin ATX, the 8 pin EPS/Xeon, and 4 pin Molex.

The 1x4 Molex connector is intended as a supplement if you have a 20-pin (as opposed to 24-pin) main connector.

From the manual:

The 2x12 main power connector on the desktop board is backwards compatible with ATX12V power supplies with 2x10 power connectors. Use of the 1x4 power connector is required with ATX12V power supplies with 2x10 connectors when using PCI Express cards that can consume up to 75 W.

The other two connectors are required.
