what do yo mean worse, like sluggish? 

 

I wouldn't just say it's the the power supply until I got my details. If its crashing than yeah you need more power or at least go back and fine tune the motherboard settings. It's possible the extra power draw is too much across all three.

Install MSI Afterburner and open up the monitoring window by detaching it from the main app.  Expand the time frame out then loop Unigine 4.0 at maximum settings. Check your clock speeds about 3 to 5 minutes into the run and you will most likely see some throttling.

its noT drop throttling it's only reaching 75 degrees C even if I overclock the CPU my benchmarking sores get worse

 

Most temp programs only take temps from the core temperature, maybe the cooler isn't cooling the VRM correctly and it throttles because those get hot.
