After 7 long years i finally get to build a brand new pc 
This will mostly be used for gaming/work(Designer) on a 27 inch 1440p monitor. I understand its overkill but I've always wanted to build something a bit overkill and i can finally do so. Just need some advice on the parts i have got and what is good/not good. Budget is around 3 .3.5k but its ok to go higher.
Going for a white build to match the room
PC Case: - I have always liked the look of the nzxt h7 elitte but not sure how good thermals will be with the new cpu /gpu + if there is enough space
Lian Li O11 Dynamic Evo (Front runner)
nzxt h7 elitte
CPU :
Intel Core i7-13700K 3.4 GHz 16-Core Processor
CPU Cooler: (Again not to sure what is the best here but because im going for a white build i assume the "Corsair iCUE H150i " should be enough?
Corsair iCUE H150i ELITE CAPELLIX 75 CFM Liquid CPU Cooler (Front runner)
Kraken X73
ARCTIC Liquid Freezer II 360
Motherboard:

Sabrent Rocket Q4 2 TB M.2-2280 PCIe 4.0 X4 NVME Solid State Drive
PSU: (The biggest issue i have right now, most people are telling me to wait for the atx 3.0 so i can get the new power cable that comes with it to make the build look cleaner but i dont really understand the difference if there is any + if its worth the extra cost
ATX 3.0 POWER SUPPLIES
Corsair HX1000 Platinum 1000 W 80+ Platinum Certified Fully Modular ATX Power Supply
