Optiplex 980 power supply

What nVidia graphic card do you have?

8800 GTS 512 Video Card

Hi newcomer and welcome to the Tom's hardware forum.

1- What form factor is the rig? Desktop, SFF or minitower.
2- Ur current PSU is ATX?, if u can post here the model of the PSU that u have in with that I can help u in a better way.

I have the same problem, it seems Dell has a proprietary thing going on the motherboard power connector called "micro atx power" or something. This stops you from installing a beefier psu (like 500W+), since the ATX power supply will not fit into the motherboard. Hopefully there is some solution avaliable soon to me (as I got a new radeon hd 5570 card I cannot use at the moment due to the built in PSU is 350W and no 12v power connector exists for PCI-e.

Anyone got a clue to what you can do about this?

No, not problem solved, as the built in PSU is only 350W and I need 450W atleast, which means I have to swap the PSU, and the new PSU won't have the mini power connector to motherboard.. Also there is no power outputs to support that even.

That wont work as the Dell PSU has only SATA connections and as noted below, is only 350.. oh well I guess I sell the Dell on Ebay now..

Look here for more info on how I got around the problem:
