Generally, the bit that takes 240v AC and turns it into the various levels required inside the computer.
[PSU]s can range from 1.5 volt wall-warts (those little black boxes intended to hang out of a wall power supply) right up. The biggest power supply I have is a two part unit, with a single phase rectifier and then a 440 volt PSU for an ancient photograph enlarger, which was used in printing photographs to paper.

There are a rats-nest of wires coming out of a PSU. There are large and small four-pin connectors intended for drives. These are called [Berg] connectors[1], and carry +5V, +12V and two ground wires.

-[2] In the case of Dell PSU's it's possible that they've 'shifted' one (or more?) wires from the ATX connector to one of the other connectors. So in theory it should be possible to hack a 'normal' PSU and turn it into a 'Dell' PSU :) Probably not worth the bother though.

According to other sites, models from the Dimension 8250 up use standard ATX PSUs, so replacement of these models is fairly straightforward

[3] Another problem with these [PSU]'s is that they could (possibly) have non-standard sizes/dimensions. A standard [PSU] will probably not fit in a [Dell] or [Gateway] casing.
