[Hardware Issue] PCIe

[spminingindustry]

Hi,

I'm facing a PCIe Extender Issue.
I tried two different kinds of PCIe Extender for a ethereum Mining Rig with Sapphire RX 470 8GB Nitro cards.
With both PCIe Extender the cards gets power, but in Windows no card is detected.

Has anybody the same problem?
Can anybody recommend a PCIe extender for Sapphire RX470/RX480 cards?

System Setup:

Motherboard: Asrock H61 Pro BTC
PowerSupply: EVGA SuperNova 1300W Gold


best regards,
Martin
