Key Features of UGREEN 70503 M.2 NVMe to PCIe Adapter
1. Convert M.2 NVMe SSD to PCIe 3.0 x4
The UGREEN 70503 CM302 converts an M.2 PCIe NVMe SSD connection into a PCI Express 3.0 x4 interface. It allows desktop users to install a compatible NVMe SSD even if their motherboard does not include a dedicated M.2 SSD connector.
Simply install your compatible M.2 SSD on the adapter and connect the card to an available PCIe expansion slot on your motherboard.
2. Supports PCIe 3.0 x4 High-Speed Interface
This UGREEN PCIe NVMe adapter supports PCIe 3.0 x4 connectivity with a maximum interface bandwidth of up to 32Gbps.
It allows a compatible NVMe SSD to communicate with your desktop system through the PCIe interface. Actual SSD read and write speeds depend on the SSD model, motherboard, PCIe generation, available lanes, and system configuration.
3. Supports Multiple M.2 SSD Sizes
The UGREEN 70503 supports four common M.2 SSD form factors, providing flexibility when installing compatible NVMe storage drives.
Supported SSD sizes include:
- M.2 2230
- M.2 2242
- M.2 2260
- M.2 2280
This broad form-factor support makes the adapter useful for upgrading desktops with different compatible M.2 NVMe SSDs.
4. M-Key NVMe SSD Compatibility
The adapter is designed for compatible M-Key M.2 PCIe NVMe SSDs and supported M-Key PCIe AHCI SSDs.
It is important to understand that M.2 is a physical form factor, not a guarantee of SSD compatibility. This adapter does not support standard M.2 SATA SSDs. Check your SSD interface and key type before purchasing.
5. Compatible with PCIe x4, x8 and x16 Slots
The UGREEN CM302 can be installed in compatible PCIe x4, x8, and x16 motherboard slots.
It supports PCIe 3.0 and backward compatibility with PCIe 2.0 and PCIe 1.0 motherboards. The actual performance depends on the PCIe generation and number of lanes available from the motherboard slot.
6. Easy Installation and Driver-Free Design
The UGREEN 70503 is designed for straightforward desktop installation. Insert a supported M.2 NVMe SSD into the adapter, secure the SSD, and install the adapter into a compatible PCIe slot.
The adapter is designed for plug-and-play operation without requiring a separate adapter driver in normal supported configurations. Operating system and motherboard compatibility still apply.
7. Multi-Layer PCB Protection
The UGREEN adapter features multi-layer PCBA protection designed to help protect the connected SSD and maintain stable operation.
Its listed protection features include:
- Overcurrent protection
- Overvoltage protection
- Short-circuit protection
- EMI interference protection
These protection features help improve the reliability of the adapter during normal operation.
Ideal for Desktop PC and Gaming PC Upgrades
The UGREEN 70503 M.2 NVMe to PCIe Adapter is useful for desktop users who want to add NVMe storage without replacing their existing motherboard.
It can be used for:
- Desktop PC storage expansion
- Gaming PC storage upgrades
- Workstation storage expansion
- Installing an NVMe SSD in a desktop without an M.2 slot
- Adding compatible high-speed storage to supported PCIe systems
- Expanding storage for large files, applications, and games
Important Compatibility Information
Before buying the UGREEN 70503 PCIe NVMe adapter, check the following:
- Your SSD must be a compatible M-Key M.2 PCIe NVMe drive.
- Standard M.2 SATA SSDs are not supported.
- The adapter requires an available PCIe expansion slot.
- PCIe x4, x8, and x16 slots are supported.
- NVMe boot support depends on your motherboard BIOS and operating system.
- The M.2 SSD is not included with the adapter.
Note: Installing an NVMe SSD through this adapter does not automatically guarantee that an older motherboard can boot Windows from it. Check your motherboard’s NVMe boot compatibility if you intend to use the SSD as a system drive.
