This motherboard has two power connectors the main 20-pin and the second auxiliary 6-pin connector. None of the new power supplies have that 2nd auxiliary 6-pin connector. I found this information on Wikipedia about it.:
A supplemental 6-pin AUX connector providing additional 3.3 V and 5 V supplies to the motherboard, if it needed it. Although it was provided by every ATX12V 1.x PSU (as required per standard), it was rarely required by motherboards.
So, do you think this motherboard will work OK without this power connecter connected to the motherboard? Thanks for your help and time. ...Steve
