First off, the Motherboard cant support the CPU, it supports higher gen CPUs(8th/9th gen) See Here

Secondly, what's the RAM's specs? just 16GB doesn't give any context :\

Thirdly, what PSU model will you be using?

that mainboard can support just 8th and 9th gen intel CPU
say intel i5 8500
blue number means CPU generation, so any CPU from 8/9 generation you can slap in there, your selection of 2nd up to 4th gen wont work
