Green PCIe card with two blue USB 3.0 ports, 19-pin header and 4-pin power connector

Manw

Manw USB 3.0 PCI-E Expansion Card 2 Port Hub 19pin Header 4pin IDE Power

SKU CH-VKM8-M17NH

Adds two USB 3.0 ports and a 19-pin internal header with 5 Gbps transfers, per-port fuses, solid capacitors and a 4-pin IDE power connector

  • Add two front USB 3.0 ports for 5 Gbps external device speeds
  • Internal 19-pin header connects motherboard front-panel USB 3.0 ports directly
  • 4-pin IDE power connector supplies up to 2 A without external adapter
  • Per-port protection fuses cut power instantly on short circuit or overcurrent
  • Solid chip capacitors rated to 250 °C ensure stable power delivery per port

Two-port USB 3.0 expansion

This Manw PCI-E card adds two external USB 3.0 ports and one internal 19-pin header for front-panel connectivity. It draws supplementary power from a 4-pin IDE connector and includes a 330 µH inductor rated above the smaller 100 µH alternative. Each port carries an independent protection fuse that cuts power during a short circuit or over-current event and resets automatically once the fault clears.

Desktop owners adding front USB 3.0

The card suits builders who need both rear and front-panel USB 3.0 ports on a system with a free PCI-E slot and an available IDE power lead. It is not for laptops, small-form-factor chassis without a full-height slot, or users whose power supply lacks a 4-pin IDE connector. Buyers who require more than two additional ports or a different internal header style should look at something else.

Slot, power and OS check

Verify the motherboard has an open PCI-E slot and that the power supply provides a spare 4-pin IDE connector. Confirm the operating system is Windows XP 32/64, Windows 7 32/64, Windows 8, 8.1 or 10, as these are the listed compatible versions. Ensure the case can accommodate a full-height bracket and that the 19-pin header matches the front-panel cable.

Questions about this item

Does my motherboard need a free PCIe slot and a 19-pin internal USB header to use this card?

Yes, the card plugs into a PCIe slot and provides two external USB 3.0 ports plus a 19-pin header for front-panel connections.

Will the 5 Gbps USB 3.0 ports work with my older USB 2.0 peripherals?

USB 3.0 is backward compatible, so USB 2.0 devices will function at their native speeds when connected to the card’s ports.

How can I verify the card is delivering stable power after installation?

Each port has an independent protection fuse and regulated capacitor; the card also uses a 330 µH inductor and solid chip capacitors rated to 250 °C for consistent supply.
