1| Can you please pass on your full system's specs like so:
CPU:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:

If this is a prebuilt system, please pass on an SKU/make and model or a link.

2| If the system shuts down when under a load scenario, it's tell tale that the PSU is giving up on it's duties. If that is true then the PSU will need replacing.
