Power Supply for Dell XPS 420

Does anyone know if this has a standard 425W psu or a special Dell one with different connections? I would hate to fit and standard one and blow the motherboard.

The Dell power supplies that come with a 24 way motherboard connector are standard ATX, however the older 20 way ones are non standard Dell specific

thanks T0SH this is a 24 way motherboards connector but it is definitely non standard now that I have the case open. The sata power leads for the hard drives must be almost 1m long. They go under the motherboard and come up between the two hard drives.

Be aware that some Dells have different colour codings for the psu wiring

thanks all - having cleaned the inside of the pc it now works perfectly. I downloaded intels tat and it shows the cores working at 34 degrees and no problems apparent. I assume that eventually the fault will reoccur and then with luck I can fix it.
