M.2 NVMe to PCIe 4.0 x4 Adapter Card – 64Gbps Desktop SSD

Upgrade Your Desktop with PCIe 4.0 NVMe SSD Speed

The OULLX M.2 NVMe to PCIe 4.0 x4 Adapter Card lets you install any M-Key NVMe SSD into a standard PCIe slot — no M.2 slot on your motherboard required. Unlock blazing-fast Gen4 transfer speeds of up to 64 Gbps (5,000+ MB/s read / 4,500+ MB/s write) and breathe new life into your desktop PC build.

⚠️ Important Notes:

• SATA / NGFF (M.2 SATA) protocol is NOT supported. This adapter is for NVMe protocol SSDs only.
• Windows 7 users: Windows 7 does not natively recognize NVMe protocol SSDs. You must install NVMe drivers via your motherboard BIOS before use. This is a Windows 7 / BIOS limitation — not an issue with the adapter card itself.

Key Features

• PCIe 4.0 x4 Bandwidth: Delivers up to 64 Gbps throughput for maximum NVMe SSD performance. Backward compatible with PCIe 1.0, 2.0, and 3.0 slots.
• Broad Slot Compatibility: Fits PCIe X1, X4, X8, and X16 slots on any standard desktop motherboard.
• Multiple SSD Form Factors: Supports M.2 NVMe SSDs in 2230, 2242, 2260, and 2280 sizes.
• Plug & Play (Win10/11): No drivers needed for Windows 10 or Windows 11 — simply install and go. Compatible with popular NVMe SSDs including Samsung 970 EVO, 950 Pro, 960 EVO, Intel SSD 6/7 Series, Plextor M6e, Kingston HyperX Predator M.2, and more.
• Multi-Layer Protection: Advanced multi-layer PCBA design with overcurrent protection, overvoltage protection, short-circuit protection, and EMI (Electromagnetic Interference) shielding — keeping your SSD safe from electrical signal interference.
• Integrated Heatsink Layer: Built-in thermal dissipation layer helps manage heat during intensive workloads.
• RoHS Certified: Compliant with RoHS regulations. No high-concern chemicals.

Frequently Asked Questions

Q: Does this M.2 NVMe to PCIe 4.0 adapter support SATA or NGFF M.2 SSDs?

A: No. This adapter card supports NVMe protocol (M-Key) M.2 SSDs only. SATA-based NGFF M.2 SSDs are not compatible and will not be recognized. Please verify your SSD uses the NVMe protocol before purchasing.

Q: Which PCIe slot sizes does this adapter fit into?

A: The adapter is designed for PCIe x4 for full Gen4 speed (64 Gbps), but it is also physically compatible with PCIe X1, X8, and X16 slots on any standard desktop motherboard. It is also backward compatible with PCIe 1.0, 2.0, and 3.0 generation slots.

Q: Do I need to install drivers to use this adapter on Windows 10 or Windows 11?

A: No drivers are required for Windows 10 or Windows 11 — it is truly plug and play. Windows 7 users, however, will need to install NVMe drivers via the motherboard BIOS, as Windows 7 does not natively support the NVMe protocol.

Q: What M.2 SSD form factors are supported?

A: This adapter supports the most common M.2 NVMe SSD sizes: 2230, 2242, 2260, and 2280. Simply seat your SSD into the M-Key slot and secure it with the included hardware.
