Adds seven USB 3.0 ports — three Type-C and four Type-A — to a desktop via a PCI Express x1 slot, delivering up to 5 Gbps transfers on Windows, macOS and Linux
This ESTONE expansion card adds seven USB 3.0 ports to a desktop through a single PCI Express x1 slot. Three ports are USB-C and four are USB-A, each capable of 5 Gbps transfer rates. The card works with PCIe 2.0, 3.0 and 4.0 motherboards and fits x1, x4, x8 or x16 slots. A driver CD is included for older Windows versions.
Suits anyone who needs more USB-C and USB-A connections for drives, cameras, VR headsets or input devices on a PC with a free PCIe slot. Not for users who require internal USB headers, laptop installations, or systems without an available PCI Express slot.
All seven ports share one PCI Express 2.0 x1 lane, so total throughput is limited to that link speed. This is the specification that determines whether the card can sustain the transfer rates your workflow demands.
Measured against everything we stock in PCIe Expansion Cards, at today’s prices. Recalculated every night.
