Hi,

From yesterday I am noticing this weird burning smell from Case TOP Exhaust and after identifying I found that it is coming from PSU it self.... This didn't happen before. At bottom where PSU fan is.. there are no smell and temperature is cool too. But at back of the PSU where the parts are and an ventilation net the air flowing too hot and rubber burning smell.

This is the picture of FAN side at bottom there is no smell here:

CPU temperature is also 60 to 70 degree celslius without gaming and with gaming above 70 to 85 degree celsius.
But Motherboard Temperature: 42 to 48 degree celsius.

*Temperature based on windows power option setting as High-Performance mode.

This is my full system rig:

Already did. :(
My bad I didn't know it before purchasing now I have to stay with this PSU for a while till I have Warranty left. It cost me 1/3 of my GPU price where I live.
But I have a question what is a better PSU would be for my RIG?. Kindly please suggest me one. I have my PC active and online 14hrs+ per day.

Thanks
