A:Answer The one I got came with a MSI z170a PC Mate, Corsair cx650m PSU, and a MSI series GTX 1080 gaming x 8g. None of which are good for overclocking. For some reason no one has had good luck OCing the 1080 gaming x from MSI. It's kind of a lottery there though. But the mother board and PSU are not good for overclocking period. They work just fine without any OC but once you turn any kind of OC on, Crash and Reboot. That's just my experience. For 4k gaming at this price point, I would build my own PC if I were you.
