my build is Xion Xon 560 White case, MSI A78M-E35 motherboard, AMD A6-6400K processor APU. Only problem I have is the Power Supply Unit. The motherboard only has 4 pin but every PSU I see has 1x6+2 pins and I can't find one that will work/compatible. Please help I don't want this to go to waste.
You confuse two connectors,the 6+2 is for a gpu and the 4pin is from the motherboard.
With just these components will the next psu already be overkill,but it will give upgrade possiblities, http://pcpartpicker.com/part/evga-power-supply-100b1050...
it's also not the most expensive.
The psu has two connectors for a gpu and one for the motherboard which is a 4+4pin (8pin),you would only need one half of that last connector to connect to your motherboard.
