Supermicro kabel CBL-MCIO-1270M5 MCIO (x8 STR naar x8 STR), 70 cm, 85 Ohm, RoHS

For dense server and storage builds where standard cables simply won't fit, the Supermicro CBL-MCIO-1270M5 delivers a lean, straight-through MCIO x8 link in a compact 70 cm length. Unlike breakout or adapter cables, this direct MCIO-to-MCIO design keeps signal integrity intact for high-speed internal connections without adding bulk or conversion overhead.

Highlights

• MCIO (Mini Cool Edge IO) x8 to x8, straight orientation on both ends
• 70 cm length — ideal for short, tidy internal runs
• 85 Ohm impedance, matched for Supermicro platforms
• RoHS compliant, built for enterprise reliability
• Supports high-speed data lanes for NVMe, SAS, or PCIe internal links

In daily use

This cable is a direct replacement or expansion part for Supermicro server and storage systems that use MCIO connectors. The straight connectors make routing simple in 1U and 2U chassis, while the 70 cm length reduces excess cable slack. The 85 Ohm impedance ensures stable signal transmission across all eight lanes, making it suitable for high-throughput storage backplanes or GPU-to-motherboard connections where MCIO is the standard.
