I mean from using inverter to main power.. inverter is a good one promising pure sinewave. must be UPS related i thought. this is 3rd PSU and all had the same noise when main power comes back online.

yeah from india but i also have home inverter. another problem i also have with PSU is the annoying sound when it switches from home inverter to main. it stays on for couple of hours... any idea what is that? i had this earlier PSU as well.

thanks for reply. looks like i should go back to using ups again.

I always used apc ups but bought a new gold PSU so decided to go without using any ups this time. which i'm not fully comfortable with. remember hearing that you don't need any ups with good power supply is this true or myth? does using ups damages PSU in anyway overtime?
