This is not an NVMe expansion slot for your PCI card, it is a powered adapter to run NVMe drives as SATA. Using the 16x expansion slot is a waste of time. The drive connectors are not for connecting additional drives to the interface, but for connecting drives to SATA slots on the motherboard. My general suggestion would be to look elsewhere for your solution. Upgrade downgraded to one star after one of my drives issued a code on this board (but it wasn't a drive).
