I want to get a minipc to mine with usb Antminers, but i need to know if the pc can deliver enough power to power 3 usbhubs.
its about this pc:http://msi.com/product/desktop/Wind-Box-DC100.html#/?div=Overview it has a 40W power adapter.
The PC does not power the hubs. You only use the data connection.
Hubs suitable for Bitcoin devices should have their own power supply.
