It would work fine, but you have some overkill going on in some places and less so in others. My thoughts are below...
CPU COOLER - A good air cooler will do just of a job, or better, for less cost.
MB - That board does not support SLI. For not much more you can keep your options open for adding a second GPU in SLI down the road.
MEM - The Z270 chipset is fine with faster modules. Just try not to go past 1.3v modules.
SSD - The Samsung EVO is nice, but not at its current cost. Look toward SK Hynix, Crucial MX300, Sandisk X400 or the WD Blue for good performers at lower prices.
GPU - Similar factory overclock for less cost with the EVGA below. Both have good cooling solutions.
PSU - Changed to a 750w unit to cover the potential...
