I would get the Seasonic 10 out of 10 times.
If this is for gaming, you could do a lot better. An i3 + RX470 or GTX1060 3GB would be about the same price.
I have FSX so I need single the i5 for it. I don't really game very much. I only play on the weekends and during I use it for homework uses and some content creation.
