Review on 🔌 Aideepen 2 Port PCIe Expansion Card with 4-Pin & 20 Pin Control Card Adapter - USB 3.0 PCI Express Controller Hub for Windows by Bennie Boss

Bought 2.1 for an old 2012 machine (Core 2nd Gen!) I'm using Ubuntu 20 as a dev box for my robot toys. I put the other in a 2019 build with a 9th Gen Core i7 and Nvidia 2070 Ti. Both were immediately recognized by the operating system without a driver update and both worked great. I don't know why the boards didn't work on some browsers. Are you not connected to the network? You MUST power it with a chassis fan connector (big old plastic white 4-pin Molex connector). The ports on the card worked and I connected the USB3 connector on the case to the connector on the board and that worked too. Very happy with both!
