What this cable delivers

This USB4 cable connects USB-C devices with a male-to-male link rated for 40Gbps data throughput and up to 240W power delivery. It suits professionals moving large media files between Thunderbolt 3 or 4 hosts and high-speed storage, as well as creators driving an 8K display at 60Hz from a compatible laptop or docking station.

Charging and display changes

The 240W rating lets a single cable charge phones, accessories and power-hungry gaming laptops when paired with a matching charger, replacing older 60W or 100W cables. Video output reaches one 8K or 5K panel at 60Hz, or two 4K panels at 60Hz, provided the host USB-C port supports DisplayPort Alternate Mode.

Build and daily use

The grey jacket covers a 3.3-foot run terminated in USB-C male plugs on both ends, with an E-Mark chip to negotiate the full power and speed envelope. Backward compatibility with USB 3.2, 3.1 and 2.0 means the same lead works across current and legacy USB-C gear without adapters or driver installs.

Questions about this item

Will the E-Mark chip or 240W PD controller need replacement after extended daily use?

The cable uses a passive E-Mark chip and 240W PD controller rated for the cable's lifetime; no scheduled replacement is required unless physical damage occurs.

At 40Gbps, does the 3.3-foot length hit a signal-integrity limit before thermal throttling on sustained transfers?

The 3.3-foot length stays within the USB4 Gen 3 0.8 m passive limit, so signal integrity holds at 40Gbps; sustained 2.8GB/s reads and 2.1GB/s writes are spec-compliant without thermal throttling.

Does the cable or its connectors get noticeably warm when delivering 240W continuously all day?

At 48V/5A the conductors are rated for the full 240W load; temperature rise stays within USB-IF limits, so the cable remains safe to handle during continuous operation.
