40 Gbps USB4 Cable for 8K Displays

This USB-C to USB-C cable delivers 40 Gbps bandwidth for professionals who need single 8K 60 Hz or dual 4K 60 Hz video output. It supports data transfer up to 40 Gbps and power delivery up to 240 W for charging laptops and accessories. The five-foot length suits desktop and dock setups.

Passive Thermals and Power Delivery

The braided passive construction produces no fan noise and adds no active heat during normal use. It carries up to 48 V at 5 A for 240 W charging when both host and charger support the profile. Data throughput reaches 40 Gbps on USB4 Gen 3 ports and 20 Gbps on Gen 2 ports.

Upgrade from 10 or 20 Gbps Cables

Replaces cables limited to 10 Gbps or 20 Gbps when an 8K 60 Hz monitor, eGPU enclosure or dual 4K workflow demands the full 40 Gbps lane. The jump is worth it only if the host port and display both operate at USB4 Gen 3 or Thunderbolt speeds. Not for users whose devices top out at lower bandwidth tiers.

Highlights

Questions about this item

How do I connect the USB4 cable to get 8K@60Hz video on my monitor?

Plug the USB-C connectors into a host port and display that both support 40Gbps bandwidth and 8K UHD 7680x4320 at 60Hz; the step often missed is confirming the host port is Gen3, not Gen2, otherwise video falls back to lower resolution.

Will the 240W charging capability degrade or need the cable replaced over time?

The cable is rated for up to 240W at 48V/5A with a compatible charger; no maintenance or scheduled replacement is required as long as the braided jacket and connectors remain undamaged.

What limits sustained 40Gbps data transfers on this 5ft cable?

The host port generation caps throughput: Gen2 ports top out at 20Gbps, while Gen3 ports allow the full 40Gbps; cable length and thermals are not the limiting factor.
