M.2 NVMe SSD to PCIe 4.0 x4 Adapter Card with Thick Copper Heatsink, PCIe Gen4 Full Speed 64Gbps Expansion Riser Card for Desktop PC Motherboard, Supports 2280 2260 2242 2230 NVMe M.2 Solid State Driv

This M.2 NVMe to PCIe 4.0 X4 expansion adapter card is an ideal storage upgrade accessory for desktop computers lacking spare M.2 slots or needing to expand high-speed solid state disk capacity. It converts the M.2 NVMe interface into a standard PCIe x4 channel through the motherboards PCIe slot, fully unlocking the maximum transmission performance of Gen4 NVMe SSDs.

Adhering strictly to PCIe 4.0 Gen4 specification, the adapter delivers a theoretical peak bandwidth of 64Gbps, perfectly matching the read and write speed of flagship NVMe M.2 solid state drives. It is downward compatible with PCIe 3.0, PCIe 2.0 and PCIe 1.0 motherboard slots, so it can still run at the maximum supported speed of older generation mainboards without hardware waste.

Overheating is the biggest factor limiting continuous high-speed operation of NVMe SSDs, so this riser card is fitted with a high-density solid copper heatsink. The large contact surface closely fits the back of the M.2 drive, rapidly conducting and dissipating heat generated during large file copying, game loading and system booting. It effectively prevents SSD thermal throttling, speed drop and automatic slowdown under sustained heavy load, greatly extending the service life of your expensive solid state drive.

The onboard M.2 socket supports four common mainstream lengths: 2230, 2242, 2260 and 2280, covering almost all consumer-grade NVMe M.2 SSDs on the market. The card uses a standard PCIe x16 physical golden finger, which can be inserted into PCIe x4/x8/x16 slots on the motherboard freely, with no extra driver required for Windows systems, realizing true plug-and-play installation.

The high-grade PCB board adopts anti-interference wiring and stable voltage circuit design, reducing signal attenuation and electromagnetic interference inside the chassis during long-term 24-hour operation. Equipped with a full-height metal fixed baffle, it locks firmly to the computer case for shock resistance and vibration prevention. It is widely used for DIY host storage expansion, video editing workstation disk array setup, game PC capacity upgrade and small server high-speed cache configuration.
