But why?? That's so stupid to have the dc to dc converter on the motherboard! Power supplies are very functional and long lasting as they are right now, no need to change them. What benefit would a 12V only PSU bring? Yes except for the very minimal power savings which won't happen because I'm betting the conversion circuit on the mobo will be of much less quality than that of a high quality psu. It doesn't save space on the motherboard, on the contrary. The connectors are as big as the old ones and the 12V to 5 and 3V3 converter circuit is added and wastes a lot of space...
