The DeLOCK PCI Express x16 card adds four internal NVMe M.2 Key M ports (2230/2242/2260/2280). It uses the Asmedia ASM2824 chipset and includes a large aluminum heatsink and a 40 mm fan for active cooling, as well as 4 status LEDs. It supports NVMe boot via UEFI (e.g. UEFI 2.3.1) and S.M.A.R.T. To use all four M.2 ports simultaneously, the motherboard must support PCIe bifurcation. Without bifurcation, only the first port can be used. It is suitable for gaming and server systems for expanding NVMe storage.
