i havent seen MSI use 4-pin cpu connector in a while.on the AMD side, all 790fx and 890fx all use 8-pin connectors.on the intel side, the only mobos with an 4-pin connector is the 775 socket and some low-end 1156.
edit:and may i add that MSI is the only one that uses Solid Hi-c Cap's.which are waaay better than the standard capacitors which deliver the best stability, reliability, overclocking and lifespan possible for a mainboard
