QNAP QXP-10G2U3A USB 3.2 Gen 2 Dual-Port PCIe Expansion Card

Overview

The QXP-10G2U3A is a low-profile PCIe expansion card that adds two USB 3.2 Gen 2 Type-A ports to compatible QNAP NAS systems, delivering up to 10Gbps per port — twice the throughput of USB 3.2 Gen 1. That bandwidth ceiling matters when connecting high-speed external storage, docking stations, or capture devices that saturate slower USB controllers under sustained load. The card supports USB Attached SCSI Protocol (UASP), which reduces CPU overhead and latency versus the older BOT (Bulk-Only Transport) standard, keeping transfer performance consistent during intensive data movement on a NAS storage system.

Compatibility

Designed for QNAP NAS enclosures and network video recorders that expose a free PCIe slot. The low-profile form factor (89.65 × 68.9 × 14 mm without bracket) is sized for compact 1U and short-depth chassis where a full-height card would not seat. Verify your target unit's PCIe slot generation and physical clearance before ordering — the card's bracket profile must match your chassis cutout. Consult the QNAP expansion accessories compatibility list for your specific NAS model to confirm slot and driver support.

Installation Notes

Operating temperature range is 0–40 °C (32–104 °F) — standard indoor rack or desktop NAS environments are within spec, but do not install in enclosures without adequate airflow where ambient temperatures can exceed 40 °C. Install with the system powered down; re-seat firmly until the PCIe edge connector is fully engaged. No additional power connectors are required beyond the PCIe slot. Driver support depends on the host NAS firmware version — confirm your QTS or QuTS hero version is current before commissioning.
