External GPU dock for Mini PCIe laptops

This docking station connects a desktop graphics card to laptops that have a Mini PCIe slot. It is aimed at engineers and developers who need GPU compute or extra display outputs for measurement, data collection or server debugging tasks. Gamers can also use most graphics cards with the dock. The unit ships without a power supply.

Check your laptop slot and power source

Verify the laptop has a free Mini PCIe, ExpressCard or M.2 A/E/M key slot for the data cable. You must provide either the dedicated 220W power adapter or a standard ATX desktop supply with the included ATX cable. The on-board DC jack accepts 12V up to 150W for lower-power cards. The USB port only delivers 500mA and carries no data.

Thermals noise and power in normal use

The dock itself has no fan; cooling depends entirely on the graphics card you install. Power draw at the wall will match the card plus dock overhead, up to the 150W or 220W limits of the chosen supply. Noise comes from the GPU cooler only. Keep the ATX PW, PTD and Slim Line switches in the default OFF position.

Questions about this item

What comes in the box and what must be purchased separately?

The dock includes the board with Mini PCIe, M.2 and PCIe x4 data cables plus 6-pin and 8-pin GPU power outputs. A 12 V DC supply up to 150 W or an ATX desktop PSU with the 220 W connector must be bought separately.

Which power-input version should I choose — the 12 V DC jack or the 220 W ATX connector?

Use the DC jack with a 12 V brick rated up to 150 W for lower-power cards; switch to the 8-pin ATX input with a desktop PSU when the graphics card needs more than 150 W.

What does the 150 W DC limit mean once the dock is installed in my laptop?

The 12 V DC jack can deliver up to 150 W to the graphics card; if your chosen GPU draws more, you must connect an ATX power supply through the 8-pin interface instead.
