Dell Optiplex

Do you have a question? Post it now! No Registration Necessary.  Now with pictures!

Threaded View
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.

Re: Dell Optiplex

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.

True, but there is no "activate PS_ON" concern, in general
given one type of PSU or the other (standard vs Dell
proprietary), a knife, soldering iron and heatshrink tubing,
they can be converted for use by swapping the pins around
(or using a pin extractor tool for most of the pins except
one or more 3.3V on the aux connector... it'll need spliced
to an ATX lead)... and I have converted some like this but I
don't know if I have the pinout anymore, it was easy enought
to determine pinout by finding the PS-On, 5VSB, and
measuring for voltage vs color with a multimeter.

Re: Dell Optiplex

You have to have RAM installed also.

What does 6 beeps mean?  I threw in some memory and got this.

If you know the kind of BIOS used, this site has listings of
POST and beep codes.

But you'd probably be better off with some Dell documentation
of some kind, because the odds of finding just the right list
of info are pretty slim.

Re: Dell Optiplex

I looked here:

http://support.dell.com/support/edocs/Systems/opgx110/ens/ug/setup.htm

It says the power button behaves differently depending on the OS
that's installed.  How does this work?

What if I have no OS?

The result you get is configurable in some OSs.
