Hey everyone,

Quick question. I have never encountered this on previous AMD boards, but on my new ASRock Z77 OC Formula, there is an additional 4 pin ATX Connector next to the 8-pin ATX power connector called the
"ATX 12V Power Connector (ATX12V2)"

Is this additional ATX 4 pin connector optional?
