My MoBO is GA-F2A55M-DS2 rev3.0. Technically, it supports PCI-E 3.0 but my APU (A4-4000) limits it to PCI-E 2.0 as per the manuals (FM2+ APU required for 3.0).
I do not have any d-GPU. The x16 slot is available.
I am looking for at least one USB3.2 or two USB3.1 slots using PCI-E 2.0 x16. Is there any such card available?
The usage is connecting faster external storage devices.
Most cards I found uses x4 which I don't think is enough for full bandwidth.
