Build Ready: A short compatibility/mistake check required please.

Hello! I hope you have a nice sunday morning!

But if you can spare a few seconds, could you please make a short check about the compatability? Or if I am missing something? I write under the parts why I chose them if neccessary.

Usecase: Gaming, rarely modern games, mostly 5 years or older titles. Also video consumption, and a little bit of work like excel or word. NO streaming or video editing and stuff like that. I have a 32" 4k 144 hz monitor, but I have no problem with running games for example at 1080p, they still look nice.

The prices are definitly ok for my country, so I'm just asking if anyone can spot an incompatability or has a suggestion where I do something extremely stupid.

It has been 9 years since my last built so I must admit I'm a bit nervous. Also I don't really have a budget, but energy efficiency is my main goal for some of the parts.

Processor: AMD Ryzen 7 7800X3D (409 Euro)

(longevity, using a i7 4770 for almost 9 years now, maybe I can repeat that)

Mainboard: ASRock B650 PG Lightning (204 Euro)

(many USB ports that I definetly will use)

RAM: G.Skill DIMM 32 GB DDR5-6000 (2x16 GB) 30-38-38-96 (113 Euro)

(low profile because big air cooler)

Air cooler: be quiet! Dark Rock Pro 4 (89 Euro)

(Silent Assassin is not available here, this was the next best thing)

Tower: be quiet! Dark Base 900

(already have it)

PSU: be quiet! Pure Power 12M 850W, 80+Gold (135 Euro)

(read good reviews)

Storage: WD Black SN850X NVMe SSD 2TB (120 Euro)

(read good reviews)

GPU: Gainward GeForce RTX 4070 Ghost OC (599 Euro)

(very energy efficient, would have liked to go the AMD route, but they are too power hungry)

Soundcard: Soundblaster X-FI Titanium

(already have it, love the features and connectivity)

Total: Around 1650 Euro
