Slimline Cable Supermicro CBL-SAST-1275A-100 90cm x8 to 4x SATA

The Slimline Cable Supermicro CBL-SAST-1275A-100 90cm x8 to 4x SATA is an internal data cable designed to expand storage connectivity inside servers and workstations. It converts a single x8 Slimline host header into four independent SATA ports, allowing connection of SATA hard drives or SSDs while maintaining a compact cable footprint. The 90 cm length offers flexibility for routing inside chassis with limited space, and the cable is intended for systems that use Supermicro-style Slimline x8 internal headers.

Advantages

This cable provides a simple and space-efficient way to increase the number of available SATA connections from a single Slimline x8 header. By splitting one internal connector into four SATA ports, it enables orderly cabling and reduces the need for additional controller cards. The 90 cm length helps reach multiple drive positions within standard server or workstation enclosures without excess slack.

Suitable for

• Expanding internal storage in rack or tower servers with a Slimline x8 host header
• Connecting up to four SATA HDDs or SATA SSDs from a single internal header
• Workstations and small servers where compact internal cable routing is required
• Systems that require direct SATA connections without adding PCIe controller cards

When it may not be suitable

This cable is not appropriate for externally accessible drive connections or for host systems that lack a compatible Slimline x8 internal header. It does not provide power; separate SATA power connections are required for each drive. Performance depends on the host controller and the SATA drives used, so it should not be relied on to change controller throughput limits.

Key specifications

• Function: internal Slimline x8 to 4× SATA data splitter cable
• Connector configuration: one Slimline x8 input, four SATA outputs
• Length: 90 cm (approx.) for internal chassis routing
• Intended use: SATA data signaling for HDDs and SSDs inside servers/workstations
• Cable type: internal data cable suited for tight routing in chassis

How to use

Install the Slimline x8 end into the matching internal host header on the motherboard or backplane, ensuring correct orientation and a secure connection. Route the cable to the drive bays, taking care to avoid sharp bends and areas with moving parts. Connect each SATA plug to a drive's SATA data receptacle and secure each drive's power connection separately. After installation, verify drive detection in the system BIOS/UEFI or operating system and confirm proper operation before returning the system to production.

What to consider before purchase

• Verify that your motherboard or backplane has a compatible Slimline x8 internal header.
• Confirm available SATA power connectors for each drive, as this cable only carries data signals.
• Check drive spacing and cable routing within your chassis to ensure the 90 cm length is sufficient.
• Ensure your host controller supports the number and type of SATA drives you plan to attach.

Usage recommendations

Use the cable in enclosed systems where internal routing keeps data connections secure and protected. Avoid excessive bending near connectors, and secure the cable to chassis points to maintain airflow and prevent strain on connectors. For optimal performance, pair with SATA drives and host controllers that meet your capacity and speed requirements.
