zimaboard 4 Ports Super Speed 5Gbps USB 3.0 PCI Express Expansion Card for Windows Linux Desktop PCs, Built in Self-Powered Technology, No Need Additional Power Supply

Although it's sold as Zimaboard, this is a generic PCI-E to 4xUSB 3.0 5gb/s.Unlike in the picture, it comes with a bracket for PC cases.It also comes with a screwdriver, two screws for the case and a mini CD with drivers. The CD is genric for a few unrelated cards.The main chip is covered by a heatsink but appears to be a Realtek controller, as expected.Each port has its own discrete power controller.As far as I can tell, it's well made with a black circuit board. The contacts within the board are painted over.There is no Zimaboard branding anywhere on the board nor the package.It's a good quality generic card.
