How We Picked
Three sourced facts: which Mac mini port is actually Thunderbolt, what each dock prints for that port, and the fact that the mini does not take power from the dock.
- The rear Thunderbolt port is the dock host. Apple’s Mac mini specifications: M6 has three Thunderbolt 4 ports at up to 40Gb/s and DisplayPort 1.4. M5 Pro has three Thunderbolt 5 ports at up to 120Gb/s and DisplayPort 2.1. The front pair are USB-C at USB 3, up to 10Gb/s. M6 can put two displays on one Thunderbolt port. M5 Pro can put three displays on one Thunderbolt port. Maximum continuous power is 155W. The box includes a 1.8 m power cord.
- A Thunderbolt 5 dock has to say what it does on Thunderbolt 4. OWC’s Thunderbolt 5 Dock lists up to 80Gb/s in each direction and up to 120Gb/s for video on a Thunderbolt 5 host, and up to 40Gb/s on Thunderbolt 4. CalDigit’s Element 5 Hub lists a Thunderbolt 5 host at up to 120Gb/s and three downstream Thunderbolt 5 ports at 80Gb/s, and says a Thunderbolt 4 computer runs at 40Gb/s. The Thunderbolt 4 Element Hub stays on Thunderbolt 4.
- Host-charging watts do not run this desktop. CalDigit’s Element 5 page says the hub does not supply power to a Mac mini. The OWC dock’s 140W line and the TS4’s 98W line are laptop charging figures. The mini plugs in with the cord in the box.
Detailed Reviews
OWC Thunderbolt 5 Dock View on Amazon
| OWC shop price | $319.99 |
|---|---|
| Thunderbolt 5 host | Up to 80Gb/s each way, up to 120Gb/s for video |
| Thunderbolt 4 host | Up to 40Gb/s |
| Other ports on the page | 2.5GbE, SD 4.0 and microSD, USB-A at 10Gb/s and 5Gb/s, 3.5 mm |
| Host charging | Up to 140W. The mini uses its own cord |
| Cable | 1.0 m Thunderbolt 5 cable in the box |
Why it fits the Mac mini. Plug it into a rear Thunderbolt port. On the M5 Pro, OWC’s own table matches the 120Gb/s video figure Apple prints for Thunderbolt 5, with data at up to 80Gb/s each way. On the M6, the same table drops to 40Gb/s, which is the Thunderbolt 4 ceiling. The OWC shop lists $319.99. That is $70.00 above the Element 5 Hub. The 2.5Gb Ethernet port matches the mini’s built-in 2.5Gb port. It does not turn the mini into the optional 10Gb Ethernet configuration.
OWC also writes that Apple Mac hosts are limited to two native displays on one Thunderbolt port. Apple’s M5 Pro specifications say three displays can share one Thunderbolt port. Those two sentences stay separate. The M6 line already stops at two displays on one port, which agrees with OWC’s Mac note. The 140W charging figure is for a notebook. This desktop already has a power cord.
CalDigit Element 5 Hub View on Amazon
| CalDigit US shop | $249.99, listed out of stock |
|---|---|
| Host | 1 Thunderbolt 5, up to 120Gb/s |
| Downstream | 3 Thunderbolt 5 at 80Gb/s, 15W each |
| USB | 3 USB-A and 2 USB-C, 10Gb/s, 7.5W each |
| Mac mini power | CalDigit says the hub does not supply power to a Mac mini |
| Size | 4.48 × 2.75 × 1.0 in, 0.44 lb. 180W supply in the box |
Why it fits the Mac mini. The host port is listed at up to 120Gb/s, which is the M5 Pro’s Thunderbolt 5 number. Three downstream Thunderbolt 5 ports are listed at 80Gb/s. CalDigit’s page says a Thunderbolt 4 computer still runs the hub, at 40Gb/s, so an M6 uses that lower line. The US shop lists $249.99 and showed the hub out of stock. That price is $70.00 under the OWC dock and $70.00 above the Thunderbolt 4 Element Hub. A 0.8 m Thunderbolt 5 cable is in the box.
The same support page says an M5 Pro can daisy-chain three Thunderbolt 5 monitors from this hub. It also has an older line that Mac hosts stop at two displays on one Thunderbolt connection. Apple’s M5 Pro specifications are the computer’s limit: three displays over one Thunderbolt port. The hub does not include Ethernet. The page is explicit that a Mac mini receives no power from the hub. The 90W host-charging line stays on the laptop side.
CalDigit Thunderbolt 4 Element Hub View on Amazon
| CalDigit US shop | $179.99, listed out of stock |
|---|---|
| Regular price on that shop | $299.95 |
| Interface | Thunderbolt 4 / USB4 |
| USB-A | Four ports at 10Gb/s |
| Displays on the page | Dual 4K at 60Hz, and an 8K display line |
Why it fits the Mac mini. The M6’s Thunderbolt ports are 40Gb/s. A Thunderbolt 4 hub matches that ceiling, and the US shop lists this one at $179.99. That is $70.00 under the Element 5 Hub and $140.00 under the OWC dock. The product page lists four USB-A ports at 10Gb/s, dual 4K at 60Hz, and an 8K display mode. The US shop showed it out of stock, with $299.95 as the regular price next to $179.99. The gap below uses $179.99.
An M5 Pro does not get its 120Gb/s video mode from this hub. Dual 4K at 60Hz sits inside the M6 two-display line, where the second screen is 4K at 60Hz over HDMI or 5K at 60Hz over Thunderbolt. It is the hub for an M6 desk that needs USB-A. The CalDigit TS4 is the 18-port Thunderbolt 4 dock, at a higher price.
If You Need Something Else
The CalDigit TS4 is the 18-port Thunderbolt 4 dock. CalDigit lists three Thunderbolt 4 ports at 40Gb/s, one of them the host, plus three USB-C ports at 10Gb/s, five USB-A ports at 10Gb/s, DisplayPort 1.4, UHS-II SD and microSD, and 2.5Gb Ethernet. Host charging is up to 98W. The US shop lists $379.99 and showed it out of stock. That is $60.00 above the OWC Thunderbolt 5 Dock, and it stays at 40Gb/s on an M5 Pro. Buy it when the port count is the point and the computer is an M6.
The front USB-C ports on the mini are USB 3 at up to 10Gb/s. A Thunderbolt dock on those ports does not become Thunderbolt. Genlock is marked unavailable on the M6 and available on the M5 Pro. None of these docks is a Genlock device.
Frequently Asked Questions
Which Mac mini port a dock should use
A rear Thunderbolt port. M6 is Thunderbolt 4 at up to 40Gb/s. M5 Pro is Thunderbolt 5 at up to 120Gb/s. The two front USB-C ports are USB 3 at up to 10Gb/s.
Whether a dock’s charging wattage runs the mini
No. The box includes a 1.8 m power cord, and maximum continuous power is 155W. CalDigit says the Element 5 Hub does not supply power to a Mac mini. The 140W, 98W, and 90W lines are laptop charging figures.
How many displays one Thunderbolt port can feed
Apple: the M6 supports up to two displays on one Thunderbolt port. The M5 Pro supports up to three. OWC’s dock page says current Mac hosts stop at two native displays on one port. CalDigit’s Element 5 page says an M5 Pro can daisy-chain three Thunderbolt 5 monitors, and it also contains an older two-display line.
What Thunderbolt 5 gear does on the M6
OWC lists 40Gb/s when the host is Thunderbolt 4. CalDigit says the Element 5 Hub runs on a Thunderbolt 4 computer at 40Gb/s. The M6 does not gain the 120Gb/s video mode by using a Thunderbolt 5 dock.
What the 2.5Gb Ethernet port on a dock adds
The mini already has a 2.5Gb Ethernet port, configurable to 10Gb when ordering. A dock’s 2.5Gb port is a second network jack. It does not raise the built-in port to 10Gb.
Final Verdict
Put a dock on a rear Thunderbolt port. The OWC Thunderbolt 5 Dock lists up to 120Gb/s for video on Thunderbolt 5 and 40Gb/s on Thunderbolt 4, at $319.99. The CalDigit Element 5 Hub lists a 120Gb/s Thunderbolt 5 host and does not power a Mac mini, at $249.99.
