model no.????
that would be a help
most likely it is a micro atx type

There are only really 3 types of psu it could be, atx, micro atx or proprietary. If its just over 120mm wide its atx, if less its micro atx.
Hp are usually quite good about listing this sort of thing in their product documentation.
