Vszerda Mini PCIe to Dual USB 3.0 20-pin Expansion Card with SATA Power

SKU CH-ZHJ9-HZFBK

Adds two USB 3.0 ports via a Mini PCIe slot using a NEC UPD720202 chipset and SATA power

  • Adds two USB 3.0 headers via Mini PCIe slot
  • NEC UPD720202 chipset delivers 5 Gbps data speeds
  • SATA 15-pin power connector supplies reliable voltage
  • Compliant with PCIe 2.0 and xHCI 1.0 specs
  • Supports Windows XP through 8 plus Linux drivers

Mini PCIe to dual USB 3.0 adapter

This Vszerda expansion card converts a motherboard Mini PCIe slot into a USB 3.0 20-pin header that provides two USB 3.0 ports. It uses the NEC UPD720202 chipset and draws power from a SATA 15-pin connector on the power supply. The card is designed for embedded or micro systems that need additional high-speed USB connectivity.

PCIe 2.0 x1 and xHCI 1.0 limits

The adapter complies with the PCI-Express 2.0 specification and the xHCI 1.0 specification. USB data transfer reaches up to 5 Gbps and remains backwards compatible with USB 2.0, 1.1 and 1.0 devices. The Mini PCIe interface supplies only a single lane, so total bandwidth is constrained by that link and the host controller implementation.

Check Mini PCIe slot and header type

Verify that the target slot is a genuine Mini PCIe interface and not an mSATA slot, as the card will not work in the latter. Ensure the motherboard has a USB 3.0 20-pin header (sometimes labelled 19-pin) for the internal cable connection. Confirm that a SATA 15-pin power connector is available from the PSU and that the operating system is among the supported Windows or Linux versions.

Questions sur cet article

Which header on my motherboard does the 20-pin connector match?

The card provides a USB 3.0 20-pin header, which is the same physical connector sometimes labelled USB 3.0 19-pin on motherboard manuals.

What real-world throughput can I expect from the NEC UPD720202 chipset?

The controller supports USB 3.0 at up to 5 Gbps and is backwards compatible with USB 2.0, 1.1 and 1.0 devices.

Why is a SATA 15-pin power cable required and what does it enable?

Mini PCIe slots do not supply 5 V power, so the SATA 15-pin connection from the PSU powers the two USB 3.0 ports for full 5 Gbps operation.
