10 Gbps PCIe NIC Network Card, Single SFP+ Port, Intel 82599EN, Compatible with Windows Server/Linux/VMware, Supports Intel X520-DA1

Works great, it took a minute to find the driver on windows

Bought 3. Worked flawlessly on my QNAP TS-473A NAS running QuTS Hero. Didn't even have to install drivers; once I powered up it was functional. Only caveat (and it is a minor one) is that the LAN light on QNAP does not light up when being used, when it used to work with the built in network. No big deal. I had to use the server bracket that came with it in order for it to fit. For my PC I did have to look for an Intel unified driver package that I found linked on Reddit which has the Intel x520 drivers I needed, but not very difficult either. Works flawlessly. Finally for the other PC, which has a vertically mounted GPU inside a y40 case, the shorter bracket once again saved the day. The price is great, it's black so it doesn't look bad inside either system. Highly recommend.

Works great.

Installation was a little tricky and I don't think there are drivers specifically for Windows 11. When you run the exe it tells you that there isn't an applicable device and cancels the install. Had to install the driver's from device manager by directing to the exe folder. After that everything seemed to work just fine. Ran speed test and it checks out.

Works great!! Installed in Asrock B650 motherboard running proxmox and it instantly connected to my Unifi Dream Machine SFP+ port via DAC at 10Gbs.

Very fast and easy to install. Only requires 4 PCIE lanes vs 8 for some other cards. Oh, and great price

Does what its supposed to and doesn't get too hot

The shield isn’t soldered on. A few pins are bent to keep it on. I had to solder it myself, which also provided proper grounding. Otherwise card works great at 10gbps.
