I assembled and purchased a new box containing an AMD 3700X, an ASUS X570 mobile device, and a couple of Sabrent Rocket nVME M2 drives (plus other <G> items) AMD- GPU 5500XT. Dan! The PSU did not have an 8-pin PCIe connector (grunt). But I found them, ordered them, they arrived (much more than Prime promised), and that was about a week ago. Finally got around to it today and installed the 5500XT with these adapters and all was good. I'm not a gamer (in fact I avoid these silly things as much as possible and don't allow them on any of my systems) but the 5500XT seems a bit sharper and more defined than the RX560 I've used before. Probably nothing measurable, but at least it's the same generation as the X570 with pcie gen 4 compatibility.
