I have measured power consumption on both the versions of hardware under different load conditions. Here are the numbers (I’ve also updated the product description):
Intel version
- Idle (typical): 10 Watts, 88 kWh per year, $11 per year (USA)
- 100% load: 21 Watts
- Powered off: 2.1 Watts
AMD version
- Idle (typical): 7.5 Watts, 70 kWh per year, $9 per year (USA)
- 100% load: 30 Watts
- Powered off: 0.9 Watts
* Assuming the device is always on
* Without any additional disks or devices connected
* Estimated yearly operating cost based on national average utility cost. See: energy.gov.
