A final update here...
I got everything a few weeks ago and it is up an running, this is the final config:
- Gigabyte GeForce RTX 3080 GAMING OC 10G
- AMD Ryzen 9 5950X
- ARCTIC Liquid Freezer II 420
- Corsair DDR4 Vengeance LPX 2x32GB 3600 Memory
- MSI MAG X570 TOMAHAWK WIFI motherboard
- 2x Samsung 970 EVO Plus 1TB M.2 SSD
- SilveStone SST-ST1200-PT 1200W ATX
- Fractal Design Meshify 2 XL Light Tint
PC is running smooth, really fast, the only problem is that the PSU is REALLY loud... so all my concerns about quietness went down the drain.
When I say loud I mean my 10 year old Roomba loud
For some reason it starts the fan for 2 seconds and it stops... it does this every few minutes and sometime it stays on for like 10 seconds and then stops.
I didn't need 1200w nor wanted a Silverstone one, but it was the only 1000W or more PSU available I could find... I will try to put it upside down to have the fan inside the case to see if gets a bit quieter, although I understand that this may cause it to be a bit hotter as it is not getting air from the outside... let's see.
