I got myself an panasonic inverter and it's giving my computer Tier 1 Cooler Master V700 80+Gold Active-PFC PSU buzzing and i regret it. Whenever it's on, my psu will buzz. I've done the test from front to back, testing each home appliances one by one. The culprit is Inverters... they may sound good, save you some electricity , but at a cost, what they output back into your house power line is square wave, thought it won't affect anything, but if your house have a bangsawan pc, like mine, it will buzz whenever the aircond wake up from slumber to cool the room. when the motor stops, the buzzing on my psu stop.

Get yourself an normal one. unless you use laptop.... go ahead with Inverters
