Supermicro CBL-PWEX-1171-2654 - kábel

Inside a dense server rack, a technician reaches past drive cages to connect a high-wattage GPU to the PSU. The Supermicro CBL-PWEX-1171-2654 makes that reach easy: a 26.5 cm PCIe power cable with an 8-pin connector on one end and a configurable 6+2 pin on the other, so it fits both 8-pin and 6-pin graphics cards. Built with 18 AWG copper conductors and a black PVC jacket, it carries clean, stable power to PCIe expansion cards in Supermicro servers and workstations.

Key specifications

• Connector 1: 8-pin PCIe male
• Connector 2: 8-pin PCIe male (6+2 pin configurable)
• Cable length: 26.5 cm
• Wire gauge: 18 AWG
• Conductor material: Copper
• Jacket material: PVC
• Colour: Black
• Compatibility: Supermicro systems, standard PCIe power interfaces

Why choose it

The 6+2 pin design means one cable handles both 6-pin and 8-pin GPUs, reducing spare parts inventory. Short length keeps airflow unobstructed in compact chassis, and the 18 AWG copper conductors minimize voltage drop under load. Supermicro engineering ensures reliable mating with their power supplies and backplanes.

Ideal use cases

• Powering a PCIe graphics card in a Supermicro 1U or 2U server
• Connecting a PCIe expansion card (e.g., NVMe adapter, FPGA) to the PSU
• Replacing a damaged or missing GPU power cable in a workstation
• Building a custom Supermicro-based system with modular PSU

Good to know

The cable is intended for internal use only, inside a chassis. It is not an extension cable; it connects directly from the power supply to the component. Always verify your PSU's PCIe power output and the card's power requirement before installation. The black PVC jacket is durable and resists abrasion in tight spaces.
