What is the brand and model of your PSU?

Those weird brands are pretty unpredictable to be honest. If I was you I would get a PSU from a well known brand like corsair or seasonic. To be 100% sure you can get a nice 550-600W 80+ Gold rated psu and you will have no issues at all. Simply powering your system with a weird psu like you have right now can simply just harm your other components.ATX 550W IGGY
