Notes:
1. Power requirement estimated for 80% VR efficiency.
2. 56% utilization for USB3 refers to current draw of 100 mA on port 1 and 900 mA on port 2; an
additional 1 A for controller power is then added to this ratio.
3. 58% utilization for back panel USB2 refers to current draw of 500 mA on port 3 and 1.0 A on port.
4. 36% utilization for internal USB2 headers refers to current draw of 100 mA on ports 5-8 and 500 mA on
port 9.
5. 20% utilization for Half-Mini Card refers to ~1 W Wi-Fi card power consumption.
6. 40% utilization for Full-Mini Card refers to ~2 W misc card power consumption.
7. 29% utilization for SATA refers to ~5 W slim ODD and ~2.5 W HDD (2.5”) power consumption.
