This article covers Cable Matters 40Gbps USB4ケーブル 0.8m.

Overview

The Cable Matters USB4 Cable (0.8m) is a high-performance USB-C cable that fully complies with the latest USB4 standard. It supports up to 40Gbps data transfer, 8K@60Hz video output, and 240W Power Delivery 3.0 charging, making it an all-in-one solution for modern notebooks and mobile devices. Compatible with iPhone 15/16, MacBook, Dell XPS, Surface Pro, and many other USB-C devices, this cable also works with Thunderbolt 4 ports, ensuring broad compatibility. With its 0.8-meter length, it's ideal for desktop setups where you need a short, tidy cable for connecting a laptop to a monitor or dock. The braided construction (assumed from typical Cable Matters cables) adds durability, though the product listing doesn't specify braiding. It's a solid choice for users who want future-proof connectivity without breaking the bank.

Connectivity & Compatibility

This cable is USB4-certified and backward compatible with Thunderbolt 4, USB 3.2 Gen 2 (10Gbps), USB 3.1, and USB 2.0. The reversible USB-C connector works on both ends, so you don't have to worry about orientation. It supports DisplayPort Alt Mode for video output, delivering up to 8K@60Hz or 4K@240Hz. For charging, it supports Power Delivery 3.0 up to 240W, but note that your device and charger must also support PD. Most modern laptops can charge at 100W, and the cable handles that without issue. Compatibility caveats: older devices with USB-C may not support the full 40Gbps speed or 240W charging. Always check your device's specifications. The cable is also compatible with Thunderbolt 3, 4, and USB4 ports, but it won't magically boost performance of older devices.

Product Info

Cable Matters is a well-known US brand for computer accessories, and this USB4 cable is part of their premium lineup. Priced at around ¥1,359 on Japan, it offers excellent value for a 40Gbps, 240W-capable cable. The cable length is 0.8 meters, which is convenient for desk use. The manufacturer typically offers a 2-year warranty, but confirm with the seller. Accessories are not included—just the cable. Market positioning: this is a high-end USB4 cable that competes with offerings from Anker, Belkin, and other brands. Its combination of 40Gbps speed, 8K video support, and 240W charging makes it suitable for power users, while the price is approachable for mainstream buyers.

Best Use Cases

USB4/Thunderbolt 4 laptop users – Ideal for connecting a MacBook Pro or Dell XPS to a high-speed external SSD or a 40Gbps dock. The cable handles data, video, and charging in one connection, reducing cable clutter. Not recommended for users who only need USB 2.0 speeds for peripherals. Creative professionals with 8K monitors – If you work with 8K video editing or high-resolution graphics, this cable provides the necessary bandwidth for stable DisplayPort Alt Mode output. It's also suitable for 4K@240Hz gaming monitors. However, for standard 4K@60Hz, a cheaper USB 3.2 cable would suffice. * Future-proofing for 240W charging – As new laptops and devices adopt higher wattage charging, this cable is ready for them. It's also great for iPhone 15/16 users who want fast charging (up to 45W with compatible charger) and data transfer. But if you only need a charging cable, a dedicated PD cable is more cost-effective.
