Pcie link downgraded with 10g NIC?

Link the bifurcation board? Are you sure you’re getting enough power on 3.3V rail?

Most m.2 to PCIe adapters pull 3.3V directly from m.2 slot, it might be a problem if your PCIe cards pull enough from 3.3v and are used simultaneously with an SSD sitting on the very same 3.3v rail from 3A regulator…

Thanks for the suggestion.

Yes, when using the bifurcation board only, it would be insufficient power for the pcie device, especially the power hungry 10G NIC which required 12V indeed.

Therefore, my set up actually included the 12V and 5V DC power supply for the standard PCIE slot…!
