Node Duo

akitio node duo features

The Node Duo, with space enough for two half-length PCIe cards, is the ultimate plug and play expansion kit for Thunderbolt 3 computers (e.g. laptop computers) where installing an internal expansion card is not an option and for systems where there is not enough space for more PCIe cards. The Thunderbolt 3 (USB-C) connection not only makes adding an external PCIe card easy but it also allows you to take the device with you to use on location and move it from one system to another.

  • Thunderbolt™ 3 for lightning fast transfer speeds up to 40 Gbps
  • 2 PCIe (x16) slots supporting two half-length, full-height, double-width cards
  • PCI Express 3.0 compliant interface with 2 lanes per slot
  • Dedicated DisplayPort for additional monitor to expand the workspace
  • 2nd Thunderbolt port supports daisy chaining of Thunderbolt 3, USB 3.1, and DisplayPort devices
  • USB power delivery provides 60W of power to recharge compatible laptops
  • Wire mesh panel to dissipate heat from cards with on-board fans
  • Big handles to easily carry the device

Two PCI Express 3.0 slots

akitio node duo interface

Supports two PCIe Gen3 x2 cards

The two PCIe slots accept half-length, full-height, double-width cards and provide 25W of power each. If only one PCIe card is installed and the power delivery function is not used, the PCIe slot can provide up to 75W of power.

Upgradeable power supply

For PCIe cards that require more power, this device can be modified accordingly. For more power, the included 150W power adapter can be replaced with a bigger power adapter (min 230W), making it possible to provide up to 75W of power to each slot. For even more power, the breakaway-tab on the back panel can be removed to create an opening, which can then be used to run a cable from an additional PSU like our 500W SFX PSU directly to the PCIe card (e.g. 6+2-pin PCIe power cable).

Two Thunderbolt™ 3 (USB-C) connectors with Power Delivery (PD)

Power Delivery (60W)

The reversible USB Type-C (USB-C) connector enhances ease of use for connecting devices with a focus on minimizing user confusion for plug and cable orientation. The Node Duo also supports power delivery (PD) over USB-C, providing up to 3A at 5V, 9V, 15V, 20V with a maximum of 60W of power to compatible laptops like the MacBook Pro (late 2016) that support charging through the USB-C cable or for devices like the iPad Pro. This allows you to recharge your battery even though the laptop is not plugged into any other power source.

Thunderbolt connectivity

Thunderbolt™ 3

Thunderbolt 3 brings Thunderbolt to USB-C at speeds up to 40 Gbps, creating one compact port that does it all – delivering the fastest, most versatile connection to any dock, display, or data device. For the first time, one computer port connects to Thunderbolt devices, every display, and billions of USB devices. A single cable now provides four times the data and twice the video bandwidth of any other cable, while also supplying power to bus-powered devices.

The Node Duo has two Thunderbolt 3 ports. The second port operates the same as a Thunderbolt 3 computer port by supporting Thunderbolt 3 (up to 5 daisy-chained), USB 3.1 (10 Gbps), and DisplayPort devices.


The dedicated DisplayPort connector makes it easy to connect an additional monitor to extend your workspace. This video output capability requires a Thunderbolt 3 connection to the computer and will free up the second Thunderbolt 3 port for Thunderbolt 3 (up to 5 daisy-chained), USB 3.1 (10 Gbps), and DisplayPort devices.

Le Node Duo est pratique parce qu’il contient deux emplacements PCI-Express. On peut donc mettre deux cartes double emplacement, tant qu’elles ne consomment pas trop (je vais y revenir). Extérieurement, il est assez large, et s’ouvre par le bas, avec deux vis à main qui permettent de faire sortir la cage du boîtier. Read More...
