Dell Optiplex

  I recently got this from ebay:
-----------------------------------------------------
Dell Optiplex GX1/GX110/GX150/GX200 System Board and PIII Processor
This System Board has been pre-tested and pulled from a working Dell
Optiplex 110 computer. It includes an Intel 866 MHZ Pentium III
Processor and heat sink.
-----------------------------------------------------

I hooked up the 2 power connectors, the "Panel" connector, and my
monitor.  Then I flipped the switch.

Nothing happened.  I expected to see some errors on my monitor about
missing an HD, etc.  Any ideas?

I found this picture of a substitute for a power supply for that
motherboard. It has a 20 pin and a 6 pin. I cannot tell if it
is a standard ATX connector or not, cause the picture isn't that
good.

If that is an ATX-like power supply, don't you have to press the
front panel power switch to start up the motherboard ?

It is my understanding that Dell, while using a 'standard' 20-pin ATX
connector, use non-standard wiring to said connector.

Google it, you may need to move some of the power connector pins around, or
buy a Dell PSU.

 I have a Dell OptiPlex GX1, so I just connected the power from that.
It fit perfectly, so I'm pretty sure it's right.

And, yes, it is a button on the front that I pushed to turn it on.

Any other ideas why it won't work?

The Dell Optiplex is an ATX *type" of computer, but uses a proprietary
type PSU that has vastly different pinouts than does a standard ATX PSU.
So not only must you activate the PS_ON circuit, but the +5v, +12v,
etc., outputs are NOT wired per ATX specification. A normally wired ATX
PSU will not work with your Optiplex MB.
