Hi, I have the ASRock H81 Pro BTC Super Alloy and an EVGE 750 G2. I have a question that may seem obvious but I cannot find info anywhere thus far.
On the mobo there are 2 PCIE power Molex slots. I understand that you need to power these slots from the PSU when using more than 2 GPUs. (we want to hook up a 3rd GPU - I presume we’d need a 2nd PSU if we were going to power more than 3)
However, the only lead which came with the PSU that has a molex connector is the cable labelled PERIF. I thought the PERIF would be used for powering things such as my external fans on my frame. Should the lead be plugged in here or do I need an adapter to plug it into one of the SATA connections?
(I notice the PERIF and SATA connectors for the PSU end have different connectors inside the end of the lead so assume they perform different functions). Hopefully this makes sense to somebody, if not can somebody link me to somewhere where I can find the answer.
Thanks in advance!
