Lekuo introduced the PB65MX3, a PCIe 4.0 B650 chipset expansion card featuring four SATA 6 Gbps ports, four M.2 NVMe slots, and multiple USB Type-C/Type-A ports. Based on the Promontory 21/B650 AMD chipset, the card enhances I/O capabilities without requiring PCIe bifurcation. Measuring 174 x 69 mm (D x H), it connects via a 6-pin power connector and targets AMD AM5 platforms, though Intel compatibility is suggested.

A DIY precursor emerged earlier this year, but Lekuo's version offers broader functionality. The card has an MSRP of $269, currently discounted to $129. Lekuo also unveiled the PR51RX1, a smaller PCIe x1 card with Ethernet and mixed USB ports, though pricing details are unavailable.
