The Antec PSU, is it High Current Gamer Gold?
The G.Skill is the Trident Z5 RGB Kit 32GB, DDR5-6400, CL32-39-39-102?
Textorm BM5, i have never heard of that before. An unknown SSD brand is a bit suspicious to me, like all components that are not sold worldwide for some reason.
Sadly you cannot really test without that SSD, but it would be something worth testing.
What are the temperatures under load, and when do the freezes happen? Can you run
HWinfo64 and show "Sensors" with all sensors expanded (click on the little <--> arrows on the bottom)? First let it run a bit while in idle, so the "minimum" baselines for the values are established. Then produce full CPU load with
Cinebench R23. After the CPU temperatures have stabilized at the highest level (let it run for 10 mins), take a screenshot. This will show everything at once. Expand the columns of the sensors a bit so everything can be read.
