Turn a delta 400lb - Computers & Internet

I don't think this model has any on/off switch on the side of the case.
Ensure that the PSU is setup for the correct a.c. input voltage.
I assume that it is the same model as here

with a 20 pin mainboard connector.
Working from this reference
http://en.wikipedia.org/wiki/ATX_PSU#Power_supply
the PSU (removed from computer) may be turned on by connecting the terminal from which the green wire emerges to any of the terminals from which black wires emerges, for example pin 16 to pin 15 in the diagram (a straightened out paper clip is often used for this purpose)
Alternatively, it easier to use a psu tester
When connected in your computer find the connector which goes to the front panel on/off button. If if it's connected simply press the on button on your computer. If its not, establish from the m/b manual which are the pins to the on/off switch and connect them together for a moment. The psu should come on.
