Could the problem be due to different atx12v?

Question

Iron

On the old MP ATX 12V was from 4 contacts (I don’t know what it’s called), and now it’s from 8, and in the PSU the wire is from 4, could there be a launch problem in this?

Answer 1

Yes, maybe this is an additional power supply per cent.

Answer 2

All my 8-pin motherboards started up smoothly when I connected a 4-pin 12V connector.
You would have a POST card in your hands, but see what and how
