I don’t really know what’s the problem that’s why I am here but maybe is a poor psu indeed

The power supply is bad - it's not even a true 750w unit. More like a 450w.

It has two +12volt rails that only put out 19A each. This is effectively not a 750 watt PSU. It appears to be Sursa made and is not acceptable quality for a gaming rig with a high end video card.

Yup, next thing to do is to replace the PSU. It's likely the problem, but even if it isn't, the junk PSU has to be removed from the equation; it's so low quality that I wouldn't even turn this PC on with a GPU attached, a problem since you have no integrated graphics. Even in the chance that this isn't the problem, one of the many issues with a very low quality PSU is that the first time anything goes wrong, you have to replace it anyway to properly diagnose an issue.

Yes you guys are right. The low quality PSU that’s installed on my pc makes it restart cause it can’t handle the rest of the hardware. I just ordered a new PSU Corsair TX850M . Thanks for the assist!!
