it does not just have to be older dells, newer ones are the same. &nbsp;arggg. &nbsp; So as justintx has suggested you will have to get one from dell so they can rip you off again.

Hard to find but they work very well, and generally much less expensive than the oem replacement even with the added cost of the adapter. I try to keep the link handy...:) T

Need to upgrade power supply for a Dell Dimension XPS R400

A desktop computer is a personal computer designed for use at a single location due to its size and power requirements, usually by one person. The most common configuration has a case that houses the power supply, motherboard, disk storage (usually one or more hard disk drives and optical disc drives); a keyboard and mouse for input; and computer monitor and printer for output. The case may be oriented horizontally and placed atop a desk or vertically and placed underneath or beside a desk.
