CalDigit TS5 Plus Thunderbolt 5 Dock review

The CalDigit TS5 Plus suits a supported high-capability desk that needs many ordinary USB sockets, a built-in 10 Gb Ethernet connection, simultaneous SD and microSD readers and up to 140 W of laptop charging. Its current exact specification lists five dedicated USB-A and five dedicated USB-C data ports, plus two downstream Thunderbolt 5 ports and DisplayPort. It is a poor fit for an ordinary 5 or 10 Gbps USB-C host, which CalDigit explicitly excludes.

Start with the actual host and the required software

The dock supports the documented Thunderbolt 5, Thunderbolt 4, Thunderbolt 3 Mac and USB4 arrangements. Thunderbolt 3 Windows PCs are expressly unsupported. Its minimum system requirements include macOS 15 or newer or Windows 11 or newer, with additional Windows processor, firmware and PCIe conditions. A Type-C connector by itself does not establish any of these requirements.

PCIe tunneling matters for USB4 hosts. CalDigit connects both the onboard network function and its second USB controller to that qualification. Confirm the computer's actual support before relying on the full dock configuration. A generic USB4 label should not silently be treated as proof that every optional host function is present.

Windows users must install the documented 10 Gb Ethernet driver. That is material if the computer is managed or a no-installation arrangement is essential. The manual also describes accessory approval through the operating system, while CalDigit's macOS ejection utility and SuperDrive driver serve their own optional functions. Those separate requirements should not be collapsed into one blanket “driver free” claim.

Map the USB sockets and the display sockets separately

The current interface list contains five 10 Gbps USB-A sockets and five dedicated 10 Gbps USB-C sockets. Those dedicated USB-C data connections do not carry display video. Two downstream Thunderbolt 5 sockets accept supported displays and peripherals, while another Thunderbolt socket is occupied by the host cable.

The front high-power USB-C socket and both downstream Thunderbolt sockets can supply up to 36 W to suitable accessories. That can be useful for an attached device with a higher charging allowance, but it is separate from the laptop's up-to-140 W connection. Other dedicated USB sockets have their own power limits, so do not assign 36 W to every Type-C-shaped port.

CalDigit describes two USB controllers rather than a single controller shared by all ordinary USB devices. That is a meaningful architecture distinction for a desk with several demanding accessories, subject to the documented host qualification. It is not a measured promise that several SSDs will copy at their individual advertised maximums simultaneously. The ordinary USB sockets are specified at 10 Gbps; the dock's Thunderbolt bandwidth does not establish USB Gen 2x2 at 20 Gbps.

Use a supported simultaneous screen arrangement

One display can use the built-in DisplayPort 2.1 connector. Further screens use downstream Thunderbolt connections, directly for compatible USB-C or Thunderbolt monitors, or through appropriate separate adapters. HDMI conversion from the DisplayPort output requires an active adapter. Native HDMI sockets are not built into this dock.

CalDigit distinguishes base M1/M2 single-screen limits, compatible base M3 closed-lid arrangements and the named Pro, Max, Ultra and newer base M4/M5 systems. Current documentation supports three displays on appropriate M5 Pro and M5 Max hosts, and up to four on M5 Max. The fourth screen requires a suitable Thunderbolt daisy chain and appropriate monitor behavior. Four screens are not four directly available display sockets.

Supported Thunderbolt 5 Windows computers have a documented triple-display route, whereas Thunderbolt 4 Windows hosts do not gain native triple-screen support. Higher resolutions and refresh rates depend on the host GPU, monitor support and any required compression. Begin with the exact host and required independent desktops in the setup finder, then verify the entire display route. Each screen using a downstream Type-C socket also occupies that socket for the purposes of connecting another separate device.

Match the network and power system to the desk

The built-in Ethernet interface has a 10 Gb link ceiling and can connect to lower-rate compatible networks. Faster networking still needs suitable equipment at the other end and an appropriate host path; this specification is not a measured internet or NAS transfer speed. Ordinary USB-C hosts are excluded altogether, and USB4 hosts need the documented PCIe support.

The front SD and microSD readers support UHS-II and can operate at the same time. For a desk that repeatedly uses both card formats, they can remove separate readers and cables. The front audio combination jack takes priority over the rear audio outputs when both are connected, so the audio connections should not be treated as independent simultaneous playback destinations.

The package includes a 330 W supply, power cord, rubber feet and a detachable 1 m braided Thunderbolt 5 cable. Allow space for the supply and cable routing as well as the dock body. The host charging ceiling is 140 W, not 330 W, and desktop Macs remain self-powered. For a smaller USB4 hub with a different set of native video connectors, compare the separately documented Anker 556 A83A8; its host, charging and Mac display restrictions need their own assessment.
