The SUPERMICRO CBL-SAST-0573, manufactured by Supermicro, is a MiniSAS HD to U.2 cable with SFF-8643 to U.2 (SFF-8639) connectors in an internal form factor. It supports 12 Gb/s SAS and SATA data transfer rates per lane.

This cable connects motherboards or RAID cards with an SFF-8643 port to storage devices using the U.2 interface, such as NVMe SSDs compatible with SFF‑8639 sockets. Designed for server and workstation use cases requiring high-speed point-to-point connections, it typically features one host-side connector (MiniSAS HD) and a single device-end plug (U.2). Power delivery depends on system configuration; additional power may be required through auxiliary sources if unsupported via this connection type alone, depending on drive specifications.
