@Spectre757 , 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 most powerful PSU that HP offers is 500W (L05757-800). It is no longer provided on HP PartSurfer, however. You will have to contact HP Customer Support to see if they can sell one to you.
Here is a Power Supply Cross-Reference Chart to show you where I got the information: https://h30434.www3.hp.com/t5/Desktop-Knowledge-Base/Power-Supply-Cross-Reference-for-specific-model...
Your model does not show the 500W PSU, but the same 180 W PSU is used several of the other models.
