Overview

The ASUS USB4-PCIE GEN4 CARD is a PCIe 4.0 x4 add-in card that brings two USB4 Type-C ports to your desktop PC. Each port supports up to 40 Gbps data transfers, 8K DisplayPort output, and 60W fast charging. It’s an easy way to add modern USB4 connectivity to any compatible system, ideal for professionals and creators who need high-speed data, video, and power delivery from a single card.

Key Features

  • Dual USB4 Type-C ports – Each port delivers 40 Gbps bandwidth independently, allowing simultaneous 8K display connections. Backward compatible with USB 3.2 and Thunderbolt 4 devices.
  • 60W USB PD 3.0 fast charging – Charge laptops, tablets, or other USB-C devices directly from the card.
  • DisplayPort 1.4 support – Output up to 8K@60Hz or 4K@120Hz via USB-C. Works with USB-C monitors and adapters.
  • PCIe 4.0 x4 interface – Provides enough bandwidth for high-speed storage or external GPU enclosures without bottleneck.
  • Auxiliary power connector – A 6-pin PCIe power input ensures stable 60W power delivery.

Compatibility & Connection Guide

  • Slot requirement – PCIe 4.0 x4 or higher (x8/x16 slots work). PCIe 3.0 slots will limit bandwidth but still function.
  • Power supply – The card draws up to 75W from the PCIe slot; for full 60W PD output, connect the 6-pin PCIe power cable. Recommended system PSU: 650W or higher.
  • OS support – Windows 11/10 and Linux (kernel 5.10+) are supported. Not compatible with macOS.
  • Display connection – Use USB-C monitors directly, or USB-C to DisplayPort cables for traditional DisplayPort monitors.

Ideal Use Cases

  • Adding USB4 to a desktop – If your motherboard lacks USB4, this card is a straightforward upgrade.
  • Multi-monitor setups – Connect two 8K displays or multiple 4K monitors for productivity or creative work.
  • Charging a laptop via desktop – Keep your USB-C laptop charged while transferring data at high speed.

Important Notes

  • Don’t forget the auxiliary power – Without the 6-pin PCIe cable, the PD output is limited. Always connect it for 60W charging.
  • Check PCIe lane sharing – Some motherboards share lanes between slots; verify your configuration to avoid performance loss.
  • Case clearance – The card is standard height, but ensure enough space for the power cable routing.
