The power supply has a 4+4 pin meaning it is an 8 pin that comes apart so it will work fine. I am not a fan of Coolermaster power supplies except the new V series but that's a different issue. Just don't stress it and it should be fine.
That board should support your APU out of the box just fine.
You should also have no problems with that RAM working with the board. However if you are using the graphics part of the APU you would benefit tremendously from higher speed RAM. Like DDR3 2133 should be the starting point and even DDR3 2400 is not a bad idea. APUs are really the only chips that greatly benefit from very high speed RAM although Intel's Haswell CPUs do well with it also. It will of course work with that RAM but your frame rates would be better with higher speed stuff.
Fantastic, thank you again for the reliable response! So just plug both 4 pins into the 8 pin and I should be fine? Yeah I realized the bit about the ram speed with an APU AFTER I purchased the ram, so I will be upgrading to 2400 when I can.
