Product Features
Technical Overview
This internal power cord utilizes industry-standard connector interfaces to ensure secure and stable power connections. The 8-pin CPU connector is keyed for proper alignment with motherboard EPS12V sockets, while the combined 8+6-pin PCIe connector delivers the necessary power rails for modern graphics cards requiring up to 225 watts of dedicated power.
The 20 AWG wire gauge provides optimal current-carrying capacity for high-wattage components while maintaining flexibility for clean cable management in compact chassis. The 1.2-foot length is specifically chosen for short-run internal routing, minimizing cable clutter while reaching between adjacent power supply and component locations in standard server and workstation configurations.
This section brings together practical product details such as First End Connector Type, First End Connector Detail, Second End Connector Type, Cord Length, so buyers can judge configuration, deployment fit, and day-to-day suitability with less guesswork.

GPU-Intensive Workstations
Ideal for content creation, engineering, and scientific workstations where powerful graphics cards need reliable supplemental power beyond the PCIe slot's capacity.
Server GPU Acceleration
Suitable for servers incorporating GPU cards for machine learning, virtualization, or rendering applications that require stable power delivery to auxiliary components.
Physical Profile
The 1.2-foot length provides just enough reach for clean internal routing between adjacent components while avoiding excess cable that can obstruct airflow. The 200-gram weight reflects the substantial wire gauge and robust connector construction, ensuring the cord maintains its position once installed without sagging or putting strain on connection points.
The physical profile is practical for deployment planning because the dimensions and weight are clearly defined: 200 g. This helps confirm rack, shelf, desk, or cabinet fit before installation.

FAQ
What devices is this power cord compatible with?
The Supermicro CBL-PWEX-0791 is designed to power graphics processing units, servers, and motherboards. It specifically supports the Nvidia GeForce GTX 980 Ti graphics card and other components requiring an 8-pin CPU connector on one end and an 8+6-pin PCIe connector on the other.
What is the length and gauge of this power cord?
This internal power cord measures 1.2 feet in length and uses 20-gauge wiring. The short length is optimized for clean internal routing in computer chassis, while the 20-gauge wire provides sufficient current-carrying capacity for high-wattage components like GPUs.
How many connectors does this cord have and what types are they?
The cord features two distinct connectors: one end has an 8-pin CPU connector for connecting to motherboard power sockets, while the other end has a combined 8-pin + 6-pin PCIe connector for delivering power to graphics cards and other PCIe devices requiring supplemental power.
Is this power cord environmentally compliant?
Yes, the CBL-PWEX-0791 complies with both RoHS (Restriction of Hazardous Substances) and REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) environmental standards. This means it is manufactured without restricted hazardous materials and meets international environmental directives.
What warranty comes with this power cord?
Supermicro provides a 24-month limited warranty for the CBL-PWEX-0791 internal power cord. This warranty covers manufacturing defects and ensures reliable performance for two years from the date of purchase when used according to specifications.
How many cords are included in the package?
The product is packaged with two identical power cords. This provides flexibility for dual-GPU configurations, spare connectivity options, or installations requiring multiple power connections within the same system or across multiple systems.
What power capacity is listed for this UPS?
Power specifications help show where the unit fits best, including the type of load level, electrical environment, and backup role it is intended to support. These are usually the most decision-critical facts in a UPS or power-protection comparison.
Is this unit designed for rack or tower deployment?
For power-protection products, the most useful FAQ topics are usually capacity, outlet arrangement, runtime characteristics, and installation format. Those details do more to explain real deployment fit than generic marketing language.
