Supermicro CBL-PWEX-1136YB-25 - kábel

When building or upgrading a high-performance workstation or server, the graphics card often sits far from the power supply, making standard cables too short. The Supermicro CBL-PWEX-1136YB-25 solves this with a 25 cm extension that bridges the gap cleanly. It connects a PCIe 8-pin male plug to an 8-pin female socket, allowing you to route power neatly behind the motherboard tray or around large CPU coolers. The black sleeving blends into any case, and the 18 AWG tinned copper conductors ensure stable 12 V delivery even under heavy GPU loads.

Key specifications

• Length: 25 cm – ideal for short extension runs
• Connector 1: PCIe 8-pin male (6+2 pin compatible)
• Connector 2: PCIe 8-pin female
• Wire gauge: 18 AWG
• Conductor material: tinned copper
• Insulation: PVC, RoHS compliant
• Colour: black

Why choose it

This extension is built to Supermicro’s server-grade standards, ensuring reliable power delivery for graphics cards and other PCIe devices. The 8-pin connectors are compatible with standard PCIe power supplies, and the 6+2 pin design on the male end adds flexibility. Tinned copper resists corrosion, while the PVC jacket withstands typical case temperatures. It’s a simple, dependable solution for cable management challenges.

Ideal use cases

• Extending GPU power cables in full-tower or rackmount chassis
• Routing cables behind motherboard trays for a cleaner build
• Replacing short or damaged PCIe power leads in Supermicro systems
• Custom PC builds where the PSU is mounted far from the GPU

Good to know

The cable is 25 cm long, measured end-to-end including connectors. It supports standard PCIe power specifications and is RoHS compliant. For high-power GPUs, ensure your power supply provides sufficient wattage on the 12 V rail. This extension does not convert voltage or increase power capacity; it simply extends the existing connection.
