Description
UGREEN 70504 Dual M.2 NVMe & SATA to PCIe 3.0 x4 Adapter Card
Add two M.2 drives to a desktop through one expansion card: an M-Key NVMe slot on PCIe 3.0 x4 (up to 32Gbps theoretical with compatible SSDs) and a separate slot for B-Key/B+M-Key M.2 SATA SSDs (up to 6Gbps when the 7-pin SATA connection is wired to a motherboard SATA port).
Supported form factors
- 2230, 2242, 2260, and 2280 M.2 sizes
Installation
Fits compatible PCIe x4, x8, or x16 slots. Includes flat and full profile brackets for flexible chassis, including 2U enclosures. No driver installation required for standard NVMe operation. Mount drives, secure with supplied hardware, seat the card, and connect the SATA cable when using the M.2 SATA slot.
Reliability
- Gold-plated PCIe interface and high-quality capacitors
- Protection against overcurrent, overvoltage, short circuits, and EMI
- Open card layout for airflow around installed SSDs
Suitable for gaming PCs, workstations, office computers, and custom desktop builds needing extra M.2 capacity.
Compatibility note: The NVMe slot uses PCIe lanes from the slot; the M.2 SATA slot requires the included SATA cable to a motherboard SATA port.
