Unlock Maximum NVMe SSD Performance with PCIe 4.0

Upgrade your desktop PC with the M.2 NVMe to PCIe 4.0 Expansion Card — available in both PCIe 4.0 x16 (4-port) and PCIe 4.0 x8 (2-port) configurations. Whether you need to multiply your storage slots or push the limits of high-speed data transfer, this adapter lets your system make the most of modern NVMe SSDs. Compatible with a wide range of M.2 form factors and operating systems, it's an ideal internal upgrade for power users, content creators, and enthusiasts. Made in Mainland China.

Choose Your Configuration

PCIe 4.0 x16 — 1-to-4 NVMe Expansion Card

  • Input Interface: PCIe x16
  • Output Interfaces: 4 × NVMe M.2 (M-Key)
  • Supported SSD Form Factors: 22110 / 2280 / 2260 / 2242
  • Supported Systems: Windows 7 / 8 / 10 / 11, Linux, macOS
  • Run up to 4 NVMe drives simultaneously on motherboards that support PCIe signal splitting
  • Backward compatible with PCIe 3.0 / 2.0 / 1.0 slots

PCIe 4.0 x8 — 1-to-2 NVMe Expansion Card

  • Input Interface: PCIe x8
  • Output Interfaces: 2 × NVMe M.2 (M-Key)
  • Supported SSD Form Factors: 2280 / 2260 / 2242 / 2230
  • Supported Systems: Windows 7 / 8 / 10 / 11, Linux, macOS
  • Run up to 2 NVMe drives simultaneously on PCIe signal-splitting motherboards
  • Backward compatible with PCIe 3.0

Key Features

  • High-Speed Data Transfer: PCIe 4.0 interface unlocks the full sequential read/write potential of modern NVMe SSDs
  • Gold-Plated Edge Connector: Gold-plated PCIe gold fingers resist oxidation, ensure reliable contact, and extend the card's lifespan
  • Broad Compatibility: Works with multiple M.2 SSD lengths — no need to swap out drives when upgrading
  • Internal Installation: Fits neatly inside your tower or workstation without cluttering your desk
  • Wide OS Support: Plug-and-play on Windows, Linux, and macOS — no extra drivers required in most cases
  • Signal Splitting Note: Full multi-drive operation requires a motherboard that supports PCIe bifurcation/signal splitting; single-SSD operation (SSD1 slot) works on all compatible motherboards

Frequently Asked Questions

Q: Does this NVMe PCIe 4.0 expansion card work without PCIe bifurcation support on my motherboard?

A: Yes, partially. On motherboards that do not support PCIe bifurcation (signal splitting), the card will still operate — but only the first SSD slot (SSD1) will be active. To use all 4 ports (x16 model) or both ports (x8 model) simultaneously, your motherboard's BIOS must support PCIe bifurcation settings. Check your motherboard manual or manufacturer website to confirm.

Q: Which M.2 NVMe SSD sizes are compatible with this expansion card?

A: The PCIe 4.0 x16 model supports 22110, 2280, 2260, and 2242 form-factor M.2 NVMe (M-Key) SSDs. The PCIe 4.0 x8 model supports 2280, 2260, 2242, and 2230 form factors. Note that only NVMe protocol SSDs are supported — M.2 SATA SSDs are not compatible.

Q: Is this card backward compatible with PCIe 3.0 slots?

A: Yes. Both the x16 and x8 models are backward compatible with PCIe 3.0 (and PCIe 1.0 / 2.0 for the x16 model). You will still benefit from expanded NVMe slots; however, the maximum throughput will be limited to your slot's PCIe generation speed rather than full PCIe 4.0 bandwidth.

Q: Do I need to install drivers for this NVMe expansion card?

A: In most cases, no additional drivers are needed. The card is designed for plug-and-play operation on Windows 7, 8, 10, and 11, as well as Linux and macOS. The operating system's native NVMe driver handles recognition automatically once the card and SSDs are seated correctly.
