You have overspecified the PSU, CPU, RAM and heatsink.
The gaming performance of this computer will be dictated by the 1050Ti, which means you're just wasting the i5K. If you don't need an i5K, you also don't need the aftermarket heatsink, because non-K processors just come with one.
The PSU is just ridiculous overkill. You're using pcpartpicker, it's telling you how much power you need, so get that.>oh, but I only spent $50 more
That's 100%. If you applied that thinking to the whole computer, it would end up costing $2000.>It's an investment
How? It's going to wear out, and power requirements just keep going down.
RAM is all made in the same three factories by the same three companies. All the stupid RAM with the stupid pricetag and the unnecessary heatsink and the styling and the branding is the exact same memory chips that're in the boring RAM that isn't marked up.
