Green circuit board with four PCIe x1 slots and a USB 3.0 cable attached

TeKit

TeKit PCI-e 1x to 4 Port Switch Hub Riser Card with USB 3.0 Cable

SKU CH-9RBZ-GP8NY

Turns one PCI-e x1 slot into four using a USB 3.0 link with a Pericom bridge chip

  • TypePCI-e Express 1x to 4 Port 1x Switch Multiplier Splitter Hub
  • Expands one PCIe x1 slot into four via Pericom PI7C9X bridge chip
  • USB 3.0 cable link delivers 625 MB/s theoretical bandwidth between cards
  • Each downstream slot runs at gen 2.0 speeds for broader compatibility
  • 150 MB/s practical throughput per port after switching overhead
  • Suits workloads within a single PCIe 1.x 250 MB/s lane budget

Expanding PCIe x1 connectivity

This TeKit riser card converts a single PCIe x1 motherboard slot into four additional x1 slots. It is intended for builders who need extra expansion capacity on boards with limited native connectors. The kit includes a main card, two equipment cards and a USB 3.0 cable linking them. It targets desktop and server platforms that require more add-in cards than the motherboard provides.

Thermal and power behaviour

The Pericom PI7C9X bridge chip handles switching between the multiplied lanes without active cooling. Power is drawn through the host slot and the USB 3.0 link, keeping consumption low during typical operation. No fan or heatsink is fitted, so noise remains negligible in normal use. The design relies on passive dissipation suited to light workloads.

Sustained load characteristics

Each divided slot operates in gen2 mode with a practical throughput around 150 MB/s after overhead. The upstream USB 3.0 connection caps theoretical bandwidth at 625 MB/s, while a native PCIe x1 gen2 lane offers 250 MB/s. Performance scales with the host slot version; gen3 (3.0) upstream is recommended for best results. Not suited for high-bandwidth cards that exceed the multiplied lane budget.

Questions about this item

How do I install the main riser card and the two equipment cards using the USB 3.0 cable?

Insert the main card into a PCIe x1 slot on the motherboard. Connect the two equipment cards to each other with the supplied USB 3.0 cable, then link them to the main card. Ensure the motherboard slot is PCIe 2.0 or 3.0 for full bandwidth.

What maintenance or replacement will the Pericom PI7C9X bridge chip or the USB 3.0 cable need over time?

The Pericom PI7C9X bridge chip is a solid-state component with no moving parts and requires no scheduled maintenance. The USB 3.0 cable carries the 5 Gbps link between cards; inspect it periodically for physical damage and replace only if the connector or wiring fails.

What bandwidth limit appears first when all four PCIe 1x slots run sustained loads?

The USB 3.0 interconnect caps theoretical throughput at 5 Gbps (625 MB/s). After protocol overhead the practical ceiling is about 150 MB/s shared across the four ports, which becomes the bottleneck before the individual PCIe 1x gen2 limit of 250 MB/s per slot.
