I suspect your power supply unit could be faulty (based on the ZEUS model ZUS700).

I believe the power supply could be faulty. I experienced an issue where the PC wouldn't start even after the first attempt. The store where I bought it checked for problems but found none. Now, to get it to work, I have to physically adjust the PSU cable. It would be great if someone could explain what might be happening.
Start with a different cable. They’re very simple to locate. If another one doesn’t fix the problem, the power supply connector might be damaged or unsecured. Avoid attempting repairs unless you’re confident. Also inspect the cables inside the computer—sometimes a loose one can cause the PSU to make contact briefly enough for it to start up. Good luck!
