What is the rest of the configuration and the power supply used ?!

It can be :
-a power supply issue ,maybe it s defective even if new (seen this myself some years ago with a build)
-a thermal protection kicking in ,make sure the CPU cooler is properly installed.

Rebuild the PC on a wooden/cardboard surface.
Use the minimum components to power it up.
