Description
The UGREEN 70503 adapter card is a high-performance expansion solution that allows you to install an M.2 NVMe (M-Key) SSD into your desktop PC via a PCI-Express slot, unlocking full PCIe 3.0 x4 speeds (up to 32 Gbps). Whether you are upgrading your workstation, boosting storage for content creation, or reviving an older system, this card offers an easy way to leverage the speed of NVMe drives without needing a dedicated M.2 slot on the motherboard.
The card supports M.2 sizes 2230, 2242, 2260 and 2280 and is compatible with PCIe 3.0, while also backwards compatible with PCIe 2.0 and PCIe 1.0 slots. Built with multi-layer PCB, over-current, over-voltage, short-circuit and EMI protections, this adapter safeguards your valuable SSD and data. Installation is straightforward — simply insert the M.2 SSD, install the bracket (standard or low profile included) into a PCIE x4/ x8/ x16 slot, and the drive is ready for use (no drivers required for most systems).
