TeKit NTRC100138W PCIe card with two USB 3.0 ports

TeKit

TeKit NTRC100138W 2-Port USB 3.0 PCI Express Card

SKU CH-Y9Y8-1KX4H

Adds two USB 3.0 ports via a PCI Express slot for up to 5 Gbps data transfer

  • Up to 5 Gbps transfer speed with USB 3.0
  • 10 times faster than USB 2.0 performance
  • Backward compatible with USB 2.0 and 1.1 devices
  • PCI Express 2.0 bus specification support
  • xHCI Revision 0.95 specification compliance

Two USB 3.0 Ports via PCI Express

This TeKit add-on card installs in a PCI Express slot to provide two external USB 3.0 connections for desktops that lack them. It targets system builders and upgraders who need SuperSpeed ports for external drives, docks or high-bandwidth peripherals. The card is not suited for users who require internal headers, more than two ports or a different slot form factor.

Sustained 5 Gbps Throughput per Port

Each port operates at the USB 3.0 signalling rate of 5 Gbps with a dedicated PCI Express 2.0 lane, so bandwidth is not shared between the two connectors. The xHCI Revision 0.95 controller maintains full speed during long transfers without throttling back to USB 2.0 rates. It does not deliver the 10 Gbps ceiling of USB 3.1 or 3.2, so workloads that saturate 5 Gbps will hit the interface limit.

PCI Express 2.0 and USB 3.0 Ceilings

The card plugs into a PCI Express 2.0 slot and is electrically limited to that generation’s single-lane throughput, which matches the 5 Gbps USB 3.0 maximum. It complies with the USB 3.0 Interface Specification and remains backward compatible with USB 2.0 and 1.1 devices at their native speeds. Systems without a free PCI Express slot or those restricted to PCI Express 1.x cannot use the card at its rated performance.

Questions about this item

Does the card draw extra power or run hot when both USB 3.0 ports are used all day?

The card can provide more power when needed and automatically reduce power consumption when not needed, so it only draws extra power while devices are actively charging or transferring data.

What slot must my motherboard have free for this TeKit NTRC100138W card to work?

A single PCI Express slot compatible with the PCI Express 2.0 bus specification is required for installation.

Will my older USB 2.0 and USB 1.1 devices still work when plugged into this card?

Yes, the card is backward compatible with USB 2.0 and 1.1 specifications, so existing peripherals will function normally on the USB 3.0 ports.
