Upgrading Video and Power Supply on an Dell XPS 400

If you have an old or even a new standard ATX PSU laying around, you could plug it in and see if the computer will boot.  If it does, then you could see if it is the same size as the old one.  That would be a bit more work though, especially if it doesn't fit.

As has been noted above... :)

Do not do that until you check the pinout on the wiring harness plug. Dell does not use standard pinouts on their power supplies. You'll either need a plug adapter or a Dell compatible PS. Otherwise you run the risk of frying your mobo.

That's not a good idea if the manufacturer of the PC is known to use proprietary plugs/sockets, (as Dell was), you could end up with a totally dead motherboard.

Dang it!  40Hz snuck in ahead of me :)

Innuendo:
Some Dells have proprietary sockets for the PSUs, but they were supposed to have gotten away from that and use standard pin-outs. The words is anything around the time of the Dimension 8400 and newer use standard pinouts.

However, a lot of their models still use proprietary form factors so while a standard PSU will work, you aren't going to get an exact fit into the case like the old one.
