## Summary description

UGREEN PCIe 3.0 x4 Adapter (model 70504) provides a connection interface for M.2 drives that use M-Key or B-Key form factors. Designed to install into a PCIe x4 slot, it enables use of compatible M.2 SSDs or modules in desktop systems. Useful for upgrading storage, adding NVMe or SATA M.2 drives where supported, and expanding system flexibility without changing the motherboard.

## Long description

UGREEN PCIe 3.0 x4 Adapter UGREEN 70504 for M.2 M-Key and B-Key Devices provides a PCIe interface card that accepts M.2 modules in M-Key and B-Key form factors. The adapter is designed to fit into a PCIe x4 slot on a desktop motherboard and enable installation of M.2 SSDs or other M.2 modules supported by the board. It offers a straightforward way to add or relocate M.2 storage to systems that have an available PCIe slot but lack an onboard M.2 socket.
Advantages
The adapter supports M.2 M-Key and B-Key devices, allowing compatibility with a wide range of NVMe and SATA M.2 modules where the host supports those interfaces. By using the PCIe 3.0 x4 interface, the card enables direct connection to the motherboard’s PCIe lanes for higher throughput when paired with compatible NVMe drives. The design simplifies upgrades and expands system flexibility without requiring a motherboard replacement.
Suitable for
 Installing M.2 NVMe or SATA modules into desktop systems with an available PCIe x4 slot
 Upgrading storage capacity or performance by adding M.2 SSDs
 Testing or using M.2 modules outside of a motherboard M.2 socket
Key specifications
 Interface: PCI Express 3.0 x4
 Supported module types: M.2 M-Key and B-Key form factors
 Supported device types: M.2 SSDs and compatible M.2 modules (NVMe or SATA where host supports)
 Form factor: low-profile/full-height bracket compatibility (depending on included bracket)
How to use
Power off the PC and open the case to access the PCIe slots. Insert the UGREEN PCIe 3.0 x4 adapter into an available PCIe x4 (or larger) slot and secure it to the chassis. Install the M.2 module into the appropriate M-Key or B-Key slot on the adapter at an angle, then press it down and fasten it with the standoff and screw supplied or already on the adapter. Close the case, power on the system, and verify device detection in the motherboard firmware or operating system. If the M.2 module requires drivers or specific BIOS settings (for NVMe or SATA operation), configure them according to the module and motherboard documentation.
Usage recommendations
Ensure the motherboard BIOS and operating system support the installed M.2 module type (NVMe or SATA) and that a PCIe x4 or larger slot is available. For optimal thermal performance with high-speed NVMe SSDs, allow adequate airflow or consider additional cooling. Use proper electrostatic discharge (ESD) precautions when handling M.2 modules and the adapter.
