[GUIDE] MBP eGPU detection issues: delayed hotplugging, PERST# switch  

Hi,

I'm planning to use my Mac mini (Late 2014) as gaming rig.

System spec:

• Mac Mini 7,1 (late 2014)
• Core i7-4578U, Dual Core @ 3.0GHz, Turbo Boost to 3.5GHz
• 16GB LPDDR3 SDRAM
• Apple SSD 256GB
• 34" Ultra wide @ Asus ROG PG348Q Gaming (3440x1440)

eGPU hardware:

• Razer Case X to fit (3x Slot Nvidia RTX 2080 Ti

• EVGA GeForce RTX 2080 Ti FTW3 ULTRA GAMING, 11GB DDR6
• Apple Thunderbolt 3 -> Thunderbolt 2 adapter
• Apple TB2 cable

Software:

• macOS Catalina 10.15.5
• BootCamp in to Windows 10 Pro (updated to latest from build 2004)
• In Win10: All drivers are updated and all Mac mini hardware is recognised (without eGPU connected)
• Apple Boot Camp updated

My current status:

1. Mac mini is connected to monitor over HDMI. Booted in Win10.
2. Mac mini <-> (TB2->TB3) <-> (TB3) Razer Case X (RTX 2080 Ti in side) -> Display port (ROG PG348Q)
3. I turn on Razer Case X.
4. I got "Display port no signal" but I do hear chim sound from Win10 and I can see new PCI Express is recognised in device manager.
5. Video card is not spinning 🙁 but I can see Razer Case is working
6. Display manager do not showing new card and Windows is not asking for any new driver installation.

Question 🙁

Should I buy bigger power supply?

Should I first install Nvidia drivers?

What should I do..?

I spend so much cash and everything was working great until moment I want to finally try eGPU rig, my "Nvidia monster" is not spinning and monitor is (Display port no signal)

Thanks in advance.
