Whilst I am waiting for your reply to PSU information forweded to you in my last message, my I return to my original question. What is the purpose of the 8 Pin ATX socket as this is something new to me.
To which you replied "You really do need to use all 8 pins of the connector. This however isn't a problem as you can use an adapter if your PSU doesn't come with the required plugs."
So in the mean time I have deduced that the additional 4 Pins are intended to supply additional current for overclocking?
The reason I state this this is that the CPU's TDP (Maximum power before thermal dissipation overload.) is around 73W. (

So although there is an 8-pin connector on the motherboard and although the BIOS of the board may require to sense some voltage there in order to power up the CPU, the actual drain on that connector I expect will be minimal if any at all.
I look forward to your reply
