<< Solved >> (MOJAVE) RX 580 get black screen when starting editing Video or opening Games

[iCoin]

Hi Everyone,
I recently built my hackintosh using this guide: https://www.tonymacx86.com/threads/...gb-ram-sapphire-rx-580-mojave-10-14-3.271145/

I copied the BIOS setting and everything. It was a SUCCESS, and macOS Mojave run smoothly.. TP-Link tl-wn822n, Wifi USB dongle works (after installing tp-link driver)
BUT..
When I start to edit video using Final Cut Pro X or playing Steam games (Dota2), my screen gone black & display disconnected.
Then, I can't do anything. Have to hard shutdown (hold power button) to turn it off.
I connected my GPU using HDMI cable to 1080p single monitor.

This is my spec:
i5 8400
Gigabyte z390 i Aorus Pro Wifi
Sapphire Nitro+ RX 580 8GB
16GB DDR4 (2x 8GB)
TP-Link tl-wn822n

And below I included my EFI folder, please help me with this issue.

Thanks a lot.

Turns out.. It was my PSU that cause the problem, i used my old PSU from my old PC build.
Then I bought a new PSU, everything runs smoothly!
