I am in search of a 550W PSU for my HP Pavilion Gaming Desktop. It has a small case that takes a specific size of power supply. I want to upgrade the graphics card because it is starting to go out after 2 years of heavy use for it currently has a Ryzen 5600 single fan and want to go with a double fan RTX 3060.
I have included a link to the model I have for size reference on what I need for a power supply.
