M.2 NVMe to PCIe 3.0 x1 Adapter Card, M-Key SSD to PCI Express x1 Expansion Card with Low Profile Bracket, Supports NVMe/AHCI SSDs (Not for SATA M.2)
- [Smart Storage Expansion] Converts one PCIe 3.0 x1 slot into an M.2 M-Key socket. This adapter is the perfect solution for adding a high-performance NVMe or AHCI SSD to a motherboard that only has a spare x1 PCIe slot available (Also perfectly fits into x4, x8, and x16 slots).
- [Strict NVMe Compatibility] Strictly supports M-Key PCIe NVMe and AHCI SSDs (sizes 2230, 2242, 2260, and 2280). ( IMPORTANT: It DOES NOT support any SATA-based B-Key or B+M Key M.2 SSDs. Please check your SSD protocol before purchasing.)
- [Low Profile & SFF Ready] Designed for maximum versatility. It comes equipped with a Low Profile bracket (half-height), making it an ideal storage upgrade solution for slim Desktop PCs, HTPCs, and SFF (Small Form Factor) cases, as well as standard ATX cases.
- [PCIe 3.0 x1 Bandwidth] Utilizes the PCI Express 3.0 x1 lane, providing stable data transfer speeds up to 1GB/s (8Gbps). Please note: Because this is an x1 lane adapter, your NVMe SSD will run at x1 speeds, which is a normal hardware limitation of the x1 slot, not a defect.
- [Plug & Play & BIOS Note] No software or drivers required for Windows 10/11, Linux, or Mac OS. ( PRO TIP: To use the NVMe SSD as a boot drive (OS drive), your motherboard's BIOS MUST natively support NVMe booting. Otherwise, it will only function as a massive storage drive.)

Maximize Your PC's Storage with the M.2 NVMe to PCIe 3.0 x1 Adapter
Running out of M.2 slots on your motherboard? Only have a tiny PCIe x1 slot left? Our Low Profile PCIe x1 to M.2 NVMe Adapter Card allows you to easily add an ultra-fast NVMe SSD to your system, reviving older motherboards or expanding storage in compact Small Form Factor (SFF) desktop computers.
Core Advantages:
- Small Form Factor Friendly: Ships with a Low Profile bracket pre-installed (or included), making it a perfect fit for slim Dell, HP, and Lenovo office desktops, or custom mini-ITX builds.
- Direct PCIe Connection: Bypasses the SATA bottleneck. Even constrained to an x1 lane (~1GB/s), an NVMe SSD over this adapter is significantly faster and more responsive than traditional SATA III mechanical hard drives or 2.5" SSDs.
- Excellent Heat Dissipation: The open-PCB design ensures that your high-speed NVMe drive receives adequate airflow inside the PC case, preventing thermal throttling during heavy data transfers.
Technical Specifications:
- Host Interface: PCI-Express 3.0 x1 (Compatible with PCIe 2.0 / 4.0 and fits into x1, x4, x8, x16 slots)
- SSD Interface: 1 x M.2 M-Key Socket
- Supported SSD Protocols: PCIe NVMe & PCIe AHCI (NO SATA SUPPORT)
- Supported SSD Sizes: 2230, 2242, 2260, 2280
- Bracket Type: Low Profile Bracket
