Pros: -Works at PCIe 3.0 speeds -Does work to adapt my NVME SSD
Cons: -Can't get it to run PCIe 4.0
Overall Review: Doesn't quite live up to the reason I purchased it. That being said, it's hard to complain when the card still functions. This was for a P5800X -- just decided to run it at gen 3 speeds.
