When your motherboard's PCIe slots are insufficient, fully occupied by graphics cards, sound cards, or other devices, or when dealing with mini PCs and industrial equipment
that only have M.2 interfaces without PCIe slots, this M.2 NGFF to PCIe 4.0 X4 expansion card becomes your ultimate interface expansion solution, effortlessly breaking through
device connection limitations.Equipped with the high-speed PCIe 4.0 X4 standard, it delivers a theoretical transmission bandwidth of up to 64Gbps, fully unleashing the performance
potential of PCIe 4.0 devices. When paired with compatible equipment such as high-speed storage drives or professional network cards, it enables ultra-fast data transfer,
significantly boosting work and usage efficiency. Additionally, the product supports backward compatibility with PCIe 3.0/2.0 versions, eliminating concerns about compatibility
with older motherboards and ensuring broader adaptability.In terms of craftsmanship and design, the product features a high-quality black PCB board with an immersion gold finish
and clear white silkscreen. This not only provides excellent oxidation resistance and stable electrical performance to ensure precise and reliable signal transmission—extending
the product's service life—but also boasts a sleek and aesthetically pleasing appearance. With a slim and compact size of 80mm × 22mm × 0.8mm, it easily fits into space-constrained
installation environments such as small chassis and industrial control equipment, eliminating worries about installation space.For power supply, the expansion card is equipped with a
SATA 15Pin Power interface, which provides continuous and stable power support for the card itself and connected PCIe devices. This effectively prevents device freezes, crashes,
or other abnormalities caused by insufficient power, ensuring stable and reliable operation even under full load conditions.Whether you're an individual user upgrading desktop hardware
to meet multi-device connection needs, expanding functional interfaces for small form factor (SFF) PCs, or supplementing PCIe interfaces for industrial control equipment in industrial
scenarios, this expansion card precisely meets your requirements. With stable performance and wide adaptability, it offers a high-quality solution for interface
expansion across various scenarios.
