Weird noice

[MamamIV]

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

It could be coil whine from your fans. Just a suggestion. I cant help other than that

It's probably a wire against the fan, screw it open and take a look. Otherwise just change the fan, cleaning it might also help.

Is it high pitched? If so, it's coil whine and there's nothing you can do about it. Don't worry, it's not harmful to any of your components.

It's probably a wire hitting the fan blades, but it might be a broken fan.

...Sorry, I had to.

 

To actually answer your question though, it sounds like a fan, and if you think it's the PSU, you should try another if you have one around, and then RMA it.
