I just received my frame, powered it without Modules and there is a very audible Noise comming from the PSU‘s, is this normal?
The noise will totally go away once you fill your Monster Frame with Modules.
It's also a good practice not to power the frame until at least 5-10% of PSU power is being consumed.  In case of the standard ±10A PSU's then at least 500-1000mA on each rail.
