Hi i am looking to upgrade my system and i am using a amd cpu but i want to go to intel and i want to use a k series chip. i was look at the comet lake cpu but when i was look at the z490 motherboards they seem to have a extra 4pin or 8pin cpu power. i am wanting to also reuse some of my parts in my current pc one being me power supply which only has 1 8pin cpu power plug.
