Hello Grischa,
I´ve bought a workstation last month with the following specs:
01 CPU AMD Ryzen TR-2950X 16/32 Core
02 KHL Enermax Liqtech TR4-240
03 LFT 120 x 120 mm Silent 4-Pin PWM
04 MOB ASUS ROG Strix X399-E Gaming
05 RAM DDR4-3200 CL16 2x16GB Skill F4-3000C16D
06 SSD Samsung 970EVO 500GB
07 NZT BeQuiet Straight Power 750W 80+ Gold modular
08 GEH Aerocool AERO 800 schwarz
It´s running fine but the first Overclocking preset with 4,1 GHz didnt work unter full load with 3dsMAX Vray rendering. Switched back to standard mode and all was working fine, with no dramatical loss in render time (about 3-5%)
In your configuration you should use a more powerful power suply, 750W should be better. In the "PC Games Hardware" I read an article, where they say, that a 900W power suply would be better, especially for overclocking. For extrem overclocking you need a water cooling better than the all in one solutions.
