The UGREEN M.2 NVMe to PCIe 3.0 x4 Adapter Card (Model: 70503 / CM302) is an internal desktop expansion card designed to add high-speed solid-state storage to computers lacking spare M.2 slots. By bridging a drive into an open motherboard PCI Express lane, it bypasses traditional SATA limits to unlock rapid data syncing.

Key Specifications & Features

Blazing 32Gbps Throughput: Operates via a PCIe 3.0 x4 interface to deliver up to 32Gbps transfer speeds, translating to roughly ~3500MB/s bandwidth to move 1GB of data in 7 seconds.
Drive Interface Compatibility: Engineered explicitly for M-Key and M+B Key NVMe PCIe SSDs. (Note: Base model 70503 does not support B-Key legacy M.2 SATA/NGFF modules, though sister variant 70504 includes a dedicated SATA bypass link).
Universal Drive Sizing: Features adjustable anchoring holes to securely fit all standard physical M.2 form factors including 2230, 2242, 2260, and 2280 lengths.
Flexible Lane Matching: Designed with a physical x4 connector configuration that plugs instantly into desktop motherboard PCIe x4, x8, and x16 slots. It is backward compatible with PCIe 2.0 and 1.0 protocols at reduced speeds.
Industrial Build & Protection: Engineered with a premium multi-layer printed circuit board assembly (PCBA) boasting gold-plated contacts and premium capacitors. It offers built-in safeguarding shields against short-circuits, overcurrent, and overvoltage.
Chassis Bracket Selection: Ships with both a full-profile standard bracket and a low-profile flat bracket, making it compatible with full-sized towers as well as slimline, small-form-factor 2U PC cases.
Driverless OS Setup: Offers native plug-and-play support across Windows 8/10/11 and Linux kernels. (Note: To use an NVMe drive as a bootable OS drive on older legacy platforms like Z87 chipsets, a custom motherboard BIOS flash is required)
