This is my first build so I am new to all of this. My mobo is a msi b350 tomahawk and it will only power on without the CPU in. When it's out, the leds will turn on and the cooler fan will spin. When I try to power it on with the CPU in, the board's leds don't even turn on. I'm doing this outside of the case with the ram in.

Triple checked that. Everything seems to be placed correctly. Is it more likely to be the CPU since everything seems to be getting power until I turn it on with the CPU installed?

Unfortunately I don't have CPU/motherboard to test. Only other comp is from like 09 with an intel chipset. Amazon is speedy so I'll have a replacement CPU tomorrow! Will post results.
