@Sirfiregod , welcome to the Community.
The motherboard in your computer is HP proprietary. It has a 4-pin power connector instead of a standard 24-pin ATX power connector. You will have to buy any PSU upgrade from HP. The problem is there is no good information on which PSU's will be compatible with your motherboard. However, I believe that the 400W (L69242-800) should be compatible: https://partsurfer.hp.com/Search.aspx?searchText=L69242-800
It is being used with the Baker motherboard (TE01-1175tx) with the same processor and memory. Here is a Power Supply Cross Reference Chart that will show you where I got the information: https://h30434.www3.hp.com/t5/Desktop-Knowledge-Base/Power-Supply-Cross-Reference-for-specific-model...
You may want to contact HP Customer Support to assure that it is compatible before ordering it.
