It's a HP or a Compaq in which case it will be ATX ... a 500w PSU should set you back about $20 - $25 ... if it's an older HP/Compaq you may have to modify where the PSU sits as they had some funny sized PSU's which had a panel riveted into the case so they'd fit ... remove the riveted panel if necessary and any ATX PSU will fitWhat kind of computer case do i have?
Looks like an atx case. You can more than likely get at least a 450 watt psu that will fit.
