I am looking for a power supply upgrade for this computer. Currently it has the stock 180W PSU. Is there a more powerful PSU that can be used on this computer that will allow me to install upgrade components, add an additional hard drive, graphics card, etc.?

Those models use a unique NON-Standard PSU. HP does make a 310W for that case, but your still limited to 75W graphic cards. It does not have an ATX 20/24 header on the motherboard.

This is quite an old thread which does have some conflicting information.
Nether of those PSU units is in the HP PartSurfer list as being compatible
