You can try the wiring trick before soldering on the backside to confirm it will work for you.

@arzen, thank you very much for the info. i will take a close look and report back.

.@invoker, hey! I know it's been ages but I'm just wondering if you'd share your benchmarks on MacOS with me for the 5700 ITX (Heaven and maybe Basemark?). Thanks!

Any luck?

@arzen, haven't got time to do it yet, but I did order a custom made cable that split a signal from +12V on the ATX connector. I will report back to you possibly next week.

.I'm excited to hear your story. If you have good results vs the rx580, I think I'll order a 5700 ITX myself.

I was able to successfully install and make work Sapphire Radeon RX 570 ITX.
All I had to do, thanks to @dope, is put a wire between PRSNT #2 of 16x (side B, pin 82) and PRSNT #2 of 8x (side B, pin 48). I don't know why it works, but it does, any insight why is it needed @dope?
At first I tried putting a wire into the slot itself to test it (green wire).
Then I soldered it on the bottom side of the pcb. Connected these two pins with a wire.

Now it works on mac mini 2018 with Mojave and Windows 10.

@arzen, I didn't, it was @dope who found out about connecting the pins. I just followed his instructions.

.@sergey_lerg, how'd you figure out which ones to solder together? 🤔

@arzen, you mean where to find the pins on the board? It's documented for the PCIE slot. I just googled the pinout and counted the pins on the board.
For example you can find the pinout here https://pinouts.ru/Slots/pci_express_pinout.shtml
