Powering-up a miniPC

I want to buy a miniPC with W10 to be used as a mediaplayer. Some systems are "advertised" as auto-powered, which means that by applying the main voltage to the power supply, the system including Windows powers up automatically. There is no need for pushing a button (like my desktop). Other systems do not say anything about it.
Since I put the mediaplayer in a cabinet, I would not prefer to have to push a button. So my question is: when autopowering is not standard, is there a way to make it work?

This depends on the motherboard bios if included as an option or not .

So if the tip or information isn't present on the Mini PC official website you can try two things :

1 - acquiring their motherboard model then research if such board supports this feature or not

or ..

2 - find the product on amazon.com then ask your question there , owners of the device often participate to tell their on hand experience

Hope this helps .

Thanks for the replies. I bought an Intel NUC for about 350 euro, including SSD, 8 Gb RAM and pre-installed W10 Pro. Fully adequate as mediaplayer. Indeed, after adjusting a BIOS setting, it is autostarting. Good advice. Next challenge now is to find the right remote.
