Need help connecting RX 9070 XT to Legion Go via Minisforum DEG2
Hi everyone,
I’m trying to connect a Sapphire/AMD RX 9070 XT to my Lenovo Legion Go using a Minisforum DEG2 eGPU dock and a be quiet! Pure Power 13 M PSU.
Current setup:
Legion Go → DEG2 via USB4
RX 9070 XT installed in DEG2
PSU connected to GPU and DEG2
USB compatibility/extended USB support enabled in BIOS
Tried booting with the Legion Go powered off and then connecting
Tried reconnecting after Windows boot
Symptoms:
When I connect USB4, the GPU fans briefly spin up and then stop.
The DEG2 appears in Device Manager as a SCSI/storage device, but the RX 9070 XT does not appear under Display Adapters.
No AMD GPU is detected in Device Manager.
No external display output.
Questions:
Is it normal for the RX 9070 XT fans to spin briefly and then stop?
Should the DEG2 itself appear somewhere specific in Device Manager when working correctly?
Are there any BIOS settings on the Legion Go besides USB compatibility that need to be enabled?
Has anyone successfully used an RX 9070 XT with a DEG2 and Legion Go over USB4?
Could this be a PSU power cabling issue even though the GPU briefly powers on?
Any troubleshooting steps would be greatly appreciated. Let me know if screenshots of Device Manager, BIOS settings, or cabling would help.
Thanks!
