Lately I've been hearing a strange almost pulsating hum from my psu and this happens when i game more intensivly and or benchmark. Problem is that it gets very loud, so loud that i can hear it through the headphones while i game. Games I've been noticing this hum are overwatch, battlefield and games were there is a lot going on at the same time.
The warranty is still active on the psu (bequiet 700w pure power https://www.inet.se/produkt/5316017/be-quiet-kraft-700w/#specs)
Just wanted to check if its the psu thats making the noice, i think it is because it still make the same noise when i've unplugged the hdd.
Here's a video of the noise
