Silverstone Technology EC04-E USB 3.0 expansion card

SKU CH-97WF-QGH0Q

Adds four USB 3.0 ports via a PCI Express 2.0 x1 slot, with two external Type-A ports and a 19-pin internal connector plus a power input for stable operation

  • Adds four USB 3.0 ports for more device connections
  • Two external Type-A ports plus internal 19-pin header for front-panel access
  • PCIe 2.0 x1 lane delivers 5Gbit/s throughput
  • Powers demanding devices via built-in power connector from PSU
  • Runs USB 3.0, 2.0 and 1.1 devices simultaneously

Two external and two internal USB 3.0 ports

This PCI Express 2.0 x1 add-in card adds four USB 3.0 ports to a desktop system. Two standard Type-A ports face the rear bracket while a 19-pin internal header supplies two more ports for front-panel or drive-bay use. It suits builders who need extra high-speed connections for external enclosures or internal hubs.

PCI Express 2.0 x1 lane limited to 5 Gbit/s

The single-lane PCIe 2.0 interface caps aggregate bandwidth at 5 Gbit/s, so all four ports share that ceiling when active simultaneously. Sustained transfers across multiple devices will therefore throttle to the bus limit rather than the per-port USB 3.0 rate. Buyers who need full 5 Gbit/s on every port at once should consider a multi-lane controller instead.

Extra power connector and low-profile bracket

A dedicated power connector draws supplementary current from the PSU, helping stability when several power-hungry peripherals are attached. The low-profile bracket fits slim chassis without modification. Users without a spare PCIe x1 slot or an available internal 19-pin header cannot install this card.

أسئلة حول هذا المنتج

Does the EC04-E need an extra power cable from the PSU to run all four USB 3.0 ports under load?

Yes, the card includes a built-in power connector so you can supply additional power from the system PSU when multiple high-draw devices are attached.

What internal header must my motherboard provide to use the card's front-panel USB 3.0 ports?

A 19-pin dual-port USB 3.0 header is required to connect the internal connector on the EC04-E.

Will the card work in an older PCIe 2.0 x1 slot without limiting the 5 Gbit/s throughput of each USB 3.0 port?

The EC04-E uses a PCIe 2.0 x1 link rated at 5 Gbit/s, matching the USB 3.0 signalling rate, so it operates at full speed in a legacy x1 slot.
