The supplied USB 3.1 naming does not by itself establish a 40Gbps mode. During sample evaluation, confirm the actual USB or USB4 specification, connector gender, charging direction, test length and certification status. The final drawing and test report should use one consistent standard name.
Data and 8K Video Verification
The specified 40Gbps and 8K 60Hz performance depends on the source, host cable, extension, dock or display and receiving device as one complete link. Test the required data rate, resolution, refresh rate, color format and audio mode at the final total length. Do not assume every laptop, monitor or console supports the same USB-C video path.
240W Power Delivery
When used in a 240W USB-C cable path, the charger, host cable, extension identification and receiving device must all support the required USB Power Delivery profile. Confirm voltage/current profiles, connector temperature, E-marker behavior and simultaneous data or video operation under load.
OEM/ODM Support
For a cable extension USB-C project, share the full connection diagram, required data and video modes, charging profiles, test length, target equipment, order quantity, branding, packaging and destination market. ChargeKeku can then confirm the sample, corrected specification and quotation.

Buyer FAQs for this configuration
What must be tested before using USB-C 3.1 Extension Cable – 40Gbps Data, 240W PD, 8K 60Hz Support for the requested video mode?
The cable specification includes 8K at 60Hz. Confirm the source connector, display connector, direction, final length, resolution and refresh rate as one complete link. The source device, adapter or dock and display must all support the requested mode.
During quotation review, does the headline USB-C power rating of the USB-C 3.1 Extension – 40Gbps Data, 240W PD, 8K 60Hz Support configuration also define its data and video capability?
No. The charging specification is 240W. The data specification is 40Gbps. The video specification is 8K at 60Hz. Power, data, video, cable length and E-marker requirements should be checked as separate fields for the exact cable.
For model selection, which connection direction should be matched for the USB-C 3.1 Extension – 40Gbps Data, 240W PD, 8K 60Hz Support configuration?
The specified connection is USB-C 3.1. Confirm the source side, device side and required function together. Connector appearance alone does not confirm charging, data or video capability.
