Scarlett 4i4 3rd Gen | power requirements

Applies to: Scarlett 4i4 3rd Gen

The Scarlett 4i4 3rd Gen audio interface is powered via the USB connection to your Mac or PC – it does not require an external power source to function.

As with all Scarlett 3rd Gen interfaces, the Scarlett 4i4 can be connected to a USB A port (using the supplied USB cable) or a USB C port using a USB C to USB C cable (not supplied). The performance will remain the same regardless of which port you use.

USB type A


USB type C



*Important* If connecting to a USB A port, you must ensure this is a USB 3.0 port. USB 2.0 ports will not be able to provide the Scarlett 4i4 with sufficient power.

USB 3.0 ports can usually be identified by a blue section inside the port (see below) though if you are in any doubt, we would advise checking with your computer’s manufacturer.
