Now now, no need to be nasty but as the OP has stated, " needs to be micro atx and under £50" and the motherboard chosen are all ATX hence it does not meet the requirements. Just because a motherboard has 4+1 VRM and does not have a VRM heatsink doesn't mean it is going to fail on you especially if there is no intention of overclocking. It is not a must to have 6+ VRM, as the 4+1 VRM is sufficient at providing the power it needs to run properly hence why Asus has also listed the FX8350 to be compatible.
AFAIK you're an Intel guy, right? So you have no experience with FX chips first hand?
Try running an 8350 on a 4 vrm phase, heatsinkless board and see how long it lasts. And your cpu will throttle in the meantime.
FX is a big pile of confusion. OEM's list cpus as compatible, but they really aren't compatible.
Example, a malossi oil filter is compatible with a Vespa. But it'll ruin your engine over time because it's an inferior grade product.
Another example, a $18 power supply will run your computer, but the horrible ripple current will ruin your components gradually and the PSU will probably drop dead in a couple of months under heavy load.
Just because something is "compatible" with something else, doesn't mean you should combine the two. It takes a little common sense
If the OP uses the board you suggested he'll never be able to overclock. He won't even be able to set his CPU to turbo on all cores at once.
Again, I think you gave bad advice, which I see is prevalent on this forum.
