Turn a Dell 1U server power supply, such as the Z670P, into a high current 12V bench supply

Supplies

Female pin header jumper wires

Step 1:

Jumper pin A1 (plugged in) to A3 (ground).

This jumper does not seem to alter power supply state in any way, other than to enable other features to work. There is no reason not to make this connection permanent if the supply is no longer being used in a Dell chassis.

Step 2: Enable Main Power Output

Jumper from B6 (12V power enable) to B3 (ground). This should enable the main power outputs.

Step 3: Other Features

Several of the small pins supply 3.3v. There are many other features possible, but the two jumpers above are sufficient to use these devices as a high-current 12V power supply.
