So you are switching from Intel to the newest AMD Ryzen. Again I don't think you are grabbing the jist of what I'm suggesting.  But yes the case will take a full size ATX PSU as WB already pointed out. All you need to do is look at the specs of what ever PSU you're considering, then measure the space inside the case to ensure you have enough room for the PSU and cabling connections. But the new motherboard will not have all the standard connectors for the case like a brand name case will. You might have issues with switches and lighting connections.

 

When you are buying a new motherboard, CPU, Graphics card, PSU and most likely you will end up buying new ram, you are building an all new system. But OK. I would mark WB2001's answer as solved as he gave you the original correct answer.

@Williamdäb,

The PSU is a standard ATX. Here are the instructions for removing.

The dimensions are shown here.  Do not exceed the 5.5" depth or it will not "lock" into place.  Not sure what your planning, but the best PSU, IMHO, the CorsiarCX650M.   It is an exact fit.

@Williamdäb 

In addition to what WB said and to clarify what you stated...

 

When you say replace everything and asked about the I/O shield, I assume you are wanting to replace the motherboard/CPU as well as the secondary parts. Is this correct?

 

If yes, you might as well buy a new and better case with better airflow,  cable management  and ease of installation. That HP case has less that OK airflow and NOT worth gutting, just to replace everything. I assume you want a newer CPU/GPU and perhaps want to overclock? A new gaming case would be mandatory!!!
