Product Overview
The ASMedia ASM4242 is an expansion card featuring a USB4 host controller chip compatible with the PCIe 4.0 interface. By adding this card to your PC, you gain access to USB4 ports with a bandwidth of up to 40Gbps, enabling high-speed data transfers and the connection of multiple high-resolution displays.
Key Features
- USB4 Support: Complies with the latest USB4 standard, delivering data transfer speeds of up to 40Gbps.
- PCIe 4.0 Interface: Utilizes a PCIe 4.0 x4 slot on your motherboard to maximize the controller's performance.
- Thunderbolt 3/4 Compatibility: USB4 is backward compatible with Thunderbolt 3 and Thunderbolt 4, allowing you to connect existing Thunderbolt devices.
- Multi-Device Connectivity: Leverage the high bandwidth to connect multiple storage devices and high-resolution monitors simultaneously.
- Broad Compatibility: Supports modern operating systems and can be integrated into various PC configurations.
Compatibility Guide
This card is recommended for motherboards equipped with a PCIe 4.0 x4 slot. It will function in a PCIe 3.0 slot, but the maximum speed will be limited by the PCIe 3.0 bandwidth. Additionally, a compatible USB4 cable is required to achieve the full performance of the USB4 port.
Ideal for These Builds
- Users who want to maximize the potential of the latest high-speed storage (e.g., NVMe SSDs).
- Creators and professionals needing to connect multiple high-resolution monitors (4K/5K and above).
- Users who own numerous Thunderbolt 3/4 devices and wish to utilize them with their PC.
- Those looking to add USB4/Thunderbolt ports to an existing PC without replacing the motherboard.
Upgrade Considerations
Ensure you have a free PCIe 4.0 x4 slot available. If you can only install it in a PCIe 3.0 slot, you won't achieve the full 40Gbps speed, but it will still offer faster connections than traditional USB 3.x ports. It's also important to consider your CPU and overall system bandwidth to avoid potential bottlenecks.
