Currently looking at the L05757-800 PSU. I'm open to others, this is merely one I found that largely fits. The L05757-800 is missing pin 2 and has three additional pins so I'm unsure if it's fully compatible.

The GPU I'm looking at is the XFX Radeon RX 560 2GB GDDR5

Welcome to our HP Community forum!
It is not clear which XFX Radeon RX 560 2GB GDDR5 model you are referring to, there is a 2GB model without the need of a 6-pin PCIe power cable, and then there are 2GB models that do require a 6-pin PCIe power cable.
If you got an XFX GPU (75-watt TDP) without the need of a 6-pin PCIe power cable, you could consider using a 310-watt power supply with p/n: L10875-800.
Or go with a 400-watt power supply which is equipped with one 6+2-pin PCIe power cable) with p/n: L04618-800.
The advantage of these two power supply units is that they are smaller-sizzed, thus making it fit better than the larger-sized L05757-800.
However, lest I forget to mention it, there is a smaller-sized 500-watt power supply with p/n: 901759-013.
All these power supplies can be purchased online, such as via eBay.
Given the uncertainties related thanks to ongoing tariffs (NOT a political statement: just stating the facts) imposed on Chinese vendors, better purchase one State-side for now if you are in the market for one.
