Asus is a very high quality product so it shouldnt fail that soon so thats why asus is my go to for mobos, tho why not check for x470 mobos? They could also be as cheap as the b450 sometimes, i found on my local online store that a basic biostar x470 mobo was going for around 70$, obviously its not the best because no heatsinks on the vrms and its a pretty basic matx board but i would reccomend x470 over b450 unless the x470 has abysmal quality, this cheap biostar doesnt have the best of quality but it should be decent and not crap out instantly
