  1. I have a Dell 4550, P4 2.4 with a 250W PSU. I have access to other Dell PSUs. How can I tell if they will fit/work? I have no way to measure them.

    Here's the model # of what I have: PS-5251-2D

    Here's what I'm looking at:

    NPS-330CB L, Used in : Poweredge 400SC and Precision 360

    NPS-350CB, Used in : Precision 370, Dimension 8400

    NPS-305AB C, Used in : Dimension 4700, 8400, Poweredge 400SC and Precision 370

    Thanks for the help!

    You can look at the wiring of the motherboard connector - it is either proprietary or standard ATX. If the mobo inside the Dell is ATX, then the PSU is some standard form factor too. Non-ATX (but still standard) PSUs use the ATX connector to the motherboard, so if you can fit the thing in the case with duct tape, then it'll work :)
