Hey. I bought a Enermax RevoBron 600w psu about 2 weeks ago and since the beginning i can hear a strange noise out of my psu. It's comming for about 70% of the time. Sometimes louder, sometimes i can't hear it at all. It sounds like something inside is vibrating a bit. I don't think it is fan, more likely it's electrical component. Sounds like a noise from an old lamp... Did some of you have the same thing? What you could suggest me to do?
