Hi, i just changed to MIVE-Z and i noticed high pitched but not so loud sound coming from psu this is on idle. Tried with another psu and it was clearly louder on that, was an older enermax 1000w. What i got now is corsair tx850, guys, any ideas? I can live with that its not that bad but just wondering didnt have that on my p67 asus board.

That's just coil whine and it's not harmful (other than to pets and people with sensitive hearing 😄 ). You might be able to make it go away by overclocking a bit (seriously).

Hehe okok, yeah i have silent fans so i notice little changes easily, and my case is just 20cm away from me. Got a little oc to 4,5ghz, overall system is running great. Thanks for the reply!
