Overview

The Monoprice 144117 is a passive Thunderbolt 4 cable certified by both Intel and the USB Implementers Forum, delivering the full 40Gbps bidirectional bandwidth that the TB4 spec mandates — twice the minimum required by USB4. At that bandwidth, a single cable connection can simultaneously carry DisplayPort 1.4 signal for dual 4K displays, PCIe data for external NVMe drives or eGPUs, and up to 240W of USB Extended Power Range charging. The 240W EPR rating is a meaningful specification jump over older 100W PD 3.0 cables, designed to stay relevant as laptop manufacturers adopt the EPR standard for power-hungry mobile workstations.

This cable is built for users who want a single-cable docking station solution: connect one TB4 cable from a laptop to a TB4 dock and get display output, peripheral connectivity, and fast charging without hunting for a separate power brick. It's equally useful for connecting an external SSD or eGPU enclosure where sustained bandwidth matters. The backward compatibility with Thunderbolt 3, USB4, USB 3.x, and USB 2.0 means it won't become a drawer orphan when plugged into older hardware — it will simply negotiate to the port's rated speed. For anyone building or upgrading a TB4 workstation setup, this is a cost-effective certified option compared to first-party cables at two to three times the price.

Key Features

Pros & Cons

👍 Pros

Intel Thunderbolt 4 and USB-IF dual-certified, guaranteeing 40Gbps performance rather than relying on marketing claims.
240W EPR Power Delivery future-proofs the cable for high-wattage laptops beyond current 140W PD 3.1 limits.
Single cable handles data, dual 4K display, and 240W power simultaneously, eliminating cable clutter on a docking station setup.
Full backward compatibility means it works on USB 3.x and Thunderbolt 3 ports without adapters or negotiation failures.
Monoprice's reputation for cable manufacturing quality at a lower price point than first-party TB4 cables from Apple or Intel partners.

👎 Cons

Passive TB4 cable design limits usable length to roughly 2m before signal integrity degrades at 40Gbps — not suitable for longer desktop-to-dock runs.
240W EPR charging requires both the charger and laptop to support USB EPR; most current devices cap at 100W PD 3.0, so the headline spec is unused on older hardware.
No built-in cable management features — the cable is round and can be stiff at shorter lengths, which matters in cramped desk setups.
Does not support Thunderbolt 5 (120Gbps) introduced in late 2023 hardware; buyers planning a TB5 system upgrade will need a new cable.

Frequently Asked Questions

Is this cable actually Intel Thunderbolt 4 certified, or just marketed as compatible?

It is fully Intel Thunderbolt 4 certified and USB-IF certified for USB4 — not a lookalike. That certification guarantees the 40Gbps bandwidth ceiling is real and that it will be recognized as a TB4 device by compliant hosts, not just fall back to USB3 speeds.

Will this cable charge my 140W or higher-wattage laptop?

Yes. The cable supports USB Extended Power Range (EPR) up to 240W Power Delivery, which covers current high-wattage laptops like the MacBook Pro 16-inch and upcoming EPR-capable systems. Your charger and laptop both need to support EPR to realize the full 240W; otherwise it negotiates down to the highest mutually supported level.

What happens if I plug this into a USB-C port that isn't Thunderbolt 4?

The cable is backward compatible with Thunderbolt 3, USB4, USB 3.x, and USB 2.0. On a non-TB4 port, it will operate at whatever the port's maximum capability is — you won't damage anything, but you won't get 40Gbps unless both ends are TB4/USB4 rated.

Can I drive two 4K monitors simultaneously from a single TB4 port using this cable?

Yes, provided your host supports DisplayPort MST or you're connecting to a Thunderbolt 4 dock that handles the multi-display split. The cable itself supports the bandwidth for dual 4K or single 8K output — the display topology is managed by the host and dock/hub, not the cable.

What length is this cable and does length affect the 40Gbps rating?

Thunderbolt 4 passive cables are typically limited to around 0.8m–2m to maintain 40Gbps. Verify the specific length of model 144117 before purchase if your setup requires more than ~1m, as longer active cables are a separate product class.
