[SOLVED] What type of power supply does this PC need?

Solution
I cannot recall the format of the smallest cutout on the back...ITX? It appears that the larger grill area is SFX?
This information may well be within the literature somewhere, but sometimes they make that aspect difficult to ascertain so that you just buy stock replacement.

Another thing I would check in addition to the room for SFX aspect is that all your motherboard and accessory cables are standard. They may well not be.
