ASUS Hyper M.2 X16 PCIe 4.0 X4 Expansion Card
Supports 4 NVMe M.2 (2242/2260/2280/22110) up to 256 Gbps in one card by utilizing PCIe 4.0 bandwidth
PCIE 4.0 X16 Interface with server-grade (low loss) PCB material, compatible with PCI express x8 and x16 slots
Supports 14W power consumption SSDs for next gen latest drives
Know before you buy
Yes, the card is compatible with both PCIe x8 and x16 slots. However, keep in mind that your motherboard must support PCIe bifurcation to recognize all four M.2 drives individually.
Yes, it supports NVMe RAID, allowing you to combine your drives for increased performance or data redundancy depending on your motherboard's BIOS capabilities.
The blower-style fan is designed to effectively manage heat for high-performance SSDs. While it is audible under heavy load, it is generally quiet during standard tasks and is essential for preventing thermal throttling.
This card supports a wide range of M.2 sizes, specifically 2242, 2260, 2280, and 22110. It is built to accommodate next-generation drives with power consumption up to 14W.
Generally, no. Since this is a PCIe expansion card, it is typically plug-and-play. You will only need to configure your BIOS settings to enable PCIe bifurcation so the system can detect all four drives.
Yes, it is backward compatible with PCIe 3.0 slots. However, you will be limited to PCIe 3.0 data transfer speeds rather than the full 256 Gbps bandwidth available with PCIe 4.0.
