The Dell DPS-500CB power supply comes from a Dell server. It only has a 12 volt output, and does not have 3.3, or 5 volts on any output. It can supply approx. 41 amps @ 12 vdc.
In order to turn the supply on, there are two sets of pins that need to be shorted. The two heavy clips to the left and right are the main 12 volt outputs. The pins in the center are 6 across, and 4 down. we will start at the top left and go down, A, B,C,D, and go across 1,2,3,4,5.6

Short A5 to B5
and
C4 to D4

You will hear a rely kick, and the fans start, then have ~ 12.4 vdc between the pin heavy clips on the left, and the other two on the far right of the connector.

rather inefficient, but you could use an inverter to make AC - then use the power supply normally. I wouldn't be too sure about opening it up, but you could apply 12v to the 12v rail inside the power supply, and hope the regulators do the rest.
