Work got me a Dell Optiplex 980 that came with a 250 watt "green" power supply. This wasn't enough to run my 4870 for gaming. I purchased a 550 watt power supply only to find out that it only accepts what Dell calls "mini 24 pin ATX" connection. I found the adapter here and figured I was set...until I got the adapter. Dell didn't follow the standard ATX pin arrangements so I had to use a voltmeter and re-arranged all the pins. Below is what I mapped by looking at the connector from the PSU side. Here's the standard 20 pin ATX pinouts. Hopefully this will help others as I couldn't find anything on the net.
