The Stand & Hub for Mac Mini / Studio is a bus-powered hub with about 15W of shared power, and an installed SSD uses about 7.5W of that. You can use a USB microphone and other peripherals, though higher-power devices may need their own power source.

Supported peripherals include:

• External hard drives, one drive at a time
• Flash drives
• USB mice and keyboards
• Headphones and microphones
• Webcams

For best results, connect one bus-powered storage device at a time.
