M.2 NVMe to PCIe X4 Adapter Card – 64Gbps, PCIe 4.0
M.2 NVMe to PCIe X4 Expansion Card – Up to 64 Gbps Full Speed
Upgrade your desktop PC's storage capabilities without needing an onboard M.2 slot. The OULLX M.2 NVMe to PCIe Adapter Card (Model SK1) lets you mount any 2230, 2242, 2260, or 2280 M.2 NVMe SSD directly into a standard PCIe slot — unlocking blazing-fast data transfer speeds of up to 64 Gbps (5000+ MB/s Read / 4500+ MB/s Write) via the PCIe 4.0 x4 channel.
⚠️ Important Notes:
- SATA / NGFF protocol is NOT supported. This adapter works with NVMe protocol M.2 SSDs only.
- Windows 7 users: Windows 7 does not natively recognize NVMe SSDs. You will need to install NVMe drivers via your motherboard BIOS before the SSD can be detected. This is a Windows 7 OS limitation, not an issue with the adapter card itself.
Key Features
- Expand Your Storage Instantly: Add an M.2 NVMe SSD to any desktop motherboard using a spare PCIe slot — no M.2 slot required.
- Blazing PCIe 4.0 x4 Speeds: Achieve up to 64 Gbps bandwidth with 5000+ MB/s sequential read and 4500+ MB/s sequential write speeds (maximum). Fully backward compatible with PCIe 1.0, 2.0, and 3.0.
- Universal Slot Compatibility: Fits in PCIe x1, x4, x8, or x16 slots on virtually any desktop PC motherboard.
- Multi-Layer Protection: Built with a multi-layer PCBA featuring overcurrent protection, overvoltage protection, short-circuit protection, EMI (Electromagnetic Interference) shielding, and an integrated heatsink layer to manage thermal output — keeping your SSD safe and stable.
- Plug & Play (Windows 10+): No driver installation needed for Windows 10 and later. Simply insert and go.
- Broad SSD Compatibility: Works with popular NVMe SSDs including Samsung 970 EVO, 950 Pro, 960 EVO, XP941, PM951, PM961, SM951, SM961; Intel SSD 6/7 Series; Plextor M6e Series; Kingston HyperX Predator M.2, and more.
