i think so but it doesn't usually happened. like only certain times and i'll hear a buzzing noise if i put my ears near the psu. i'm 100% confirm that noise are not from my mobo or graphic card.
if i want to overclock a processor, i need to have a Z170 board + a "K" processor? i'm sorry if my question annoys you. I'm still newbie to be honest. My first gaming rig i build December 2016
Thank you for your useful replies. This is why i like to talk with LTT community. One last question, so if have a processor that have a "K" at the end, meaning that i can overclock that processor?
