Interesting you brought up DDR4-4000 2x16GB. Kits like that are not common. Outside of the Crucial products (which seem to be tightly-binned Micron e-die), I can't 100% tell which ICs are in these things. If it's b-die then you're looking at 4 ranks which could cause problems with achieving advertised clockspeeds. Anyway the Crucial DIMMs should be 2 ranks total. That Ripjaws V kit looks interesting though:
The Crucial kit is around $80 more and has worse timings.
That aside, beware EVGA PSUs unless you're going to be looking at something like a P2-series (which are still pretty good, but overpriced for what they are). Anything newer than their G3 series should be held in some suspicion.
edit: if I were going for 850W PSU right now, I would be looking at:
