How to organize the inclusion of a computer through raspberry pi (or its clone)?

Question

Iron

Hello. I asked myself the question of turning on the computer using banana pi (clone of raspberry pi). But, alas, I am new to electronics.
I see it like this:
the computer power button closes 2 contacts on the motherboard. so I need to connect a device in parallel that closes them .. as far as I understand this is a relay. it will be controlled from banana pi.
Please correct me if I'm wrong somewhere in my reasoning.
The question itself is (if my plan is correct) what characteristics should this relay have? those. What do I need to say when I arrive at the store?

Answer 1

Can't wake up from wakeonlan?

Answer 2

In addition to the relay, a transistor is also needed. the current consumption of the relay may turn out to be more than x-pi can give out, details here:

: use an opto relay. switching current 8-10mA - should be enough.
