Overview
The ASUS Hyper M.2 x16 Gen 5 Card is a PCIe expansion card that lets you install up to four M.2 NVMe SSDs using a single PCIe 5.0 x16 slot. With double the bandwidth of Gen 4, it unlocks the full speed of the latest Gen 5 drives. Ideal for content creators needing massive fast storage or gamers who want lightning-fast load times across multiple titles.
Key Features
- PCIe 5.0 x16 interface (backward compatible with Gen 4 and Gen 3 SSDs)
- Four M.2 slots (M-key, NVMe only)
- Each slot gets dedicated x4 lanes (x4 x4 x4 x4 configuration)
- Large heatsink and backplate for efficient thermal management
- OS support: Windows 11/10, Linux (UEFI boot)
Compatibility Guide
- Slot requirement: PCIe 5.0 x16 (physical x16) is recommended. Works in PCIe 4.0 x16 slots with reduced bandwidth.
- Motherboard form factor: ATX or E-ATX recommended. Mini-ITX may not physically fit.
- Supported SSDs: M.2 2280/2260/2242 NVMe (PCIe 5.0/4.0/3.0). SATA M.2 SSDs are not supported.
- BIOS setting: You may need to enable PCIe lane bifurcation (x4x4x4x4) in the motherboard BIOS.
Ideal Use Cases
- Video editing workstations requiring multiple high-speed NVMe drives
- Gamers who want separate SSDs for different game libraries
- Virtualization setups where each VM gets a dedicated SSD
Upgrade Considerations
- Check your motherboard's PCIe lane allocation. If CPU lanes are limited, the GPU may drop to x8 mode when this card is installed. On modern Intel LGA1700 and AMD AM5 platforms, the primary x16 slot is usually CPU-direct, so this card should use a chipset-connected slot to avoid GPU bandwidth loss.
- Physical clearance: The card occupies two slots due to its heatsink. Ensure adjacent slots are free.
- Power: The card draws power from the PCIe slot itself, but with four Gen 5 SSDs under full load, a system PSU of 850W or higher is recommended for stability.
