Same thing for other brands like ASUS where you can have a great variety of quality boards and then have something like a M5A78L-M LX Plus that doesn't have enough VRM to support the CPUs on its CPU supported list (they even put a FX-8370 on the list, which is no bueno for that cheapy 3+1 setup).
Well its really a 95W board limit. The FX support are only the 95W CPUs. As in the 8320 and 8370E models.
