are this parts compatible with each other

Solution
They are compatible. If pcpartpicker does not flag it then it is okay.

But there could be changes. Change the mobo for one, the VRM on that is a joke and will last not long.

Cooler is okay for basic but if you are OC'ing it will struggle. Change it.

Better PSU needed.

No SSD?

Better PSU. Better GPU. SSD.
 
Solution


Better PSU. Step down the CPU to an 8400 and drop the cooler, use the stock one. Step down to a 1 TB HDD, keep the GPU for now. Otherwise good.

Also, did you already buy the RAM? It is not listed with a price tag.
