[Francesco91]

Hi. I'm francesco and yesterday i try to make my first hackintosh

i buy

i7 8700k
gigabyte z370 aorus gaming 7
rog astrix rx580 8gb
16gb ram corsair vengaence (yellow)
corsair water cooler h60
samsung 960 evo 500gb
evga 750watt power

I have assemble it and i use clover method for installation...but i use all without rx580 plugged in because when i try to power on first time it doesn't go. After some trying i decide to plugged off rx580. I make all installation and now i can launch SO

Now i want to install rx580, wlan archer t9e and my second (but hdd) drive 4tb of WD blue.

I start with rx580. I give cable from power and i link it with rx580...i install it on second pci slot (but i try initially in first slot and don't go). see video for make an idea

I give cable from power and i link it with vga

VGA is unsupported - Apple do not use it.
Use a digital connection.

For example? However before I install macOS, when I build pc with new products and without a os installed (no windows and no macOS, a new pc) pc not show nothing: no bios, no loading, nothing. If I plugged it off I can run bios, change options and make installation of macOS. For this reason i think it isn’t problem.

Send me a pic of this cable

However I want to say “I give cable from power and I link rx580”, not vga
