The +12V rail's over-current protection (OCP) triggering point can be configured through the Corsair Link software. We checked its accuracy with various loads and found it to be almost spot-on. The minor rails are allowed to go way too high before OCP kicks in, and the same goes for the 5VSB rail.

Over-power protection (OPP) kicks in once you try to draw more than 1900W, while over-temperature protection is configured properly. Short-circuit protection is implemented on every rail, the power-good signal is accurate, and surge/inrush current protection (SIP) is included.

    Videos working fine here.

    PCs are more efficient, however graphics cards once pushed are not and many users tend to overclock their GPUs. Moreover, those units are intended for multi-GPU systems.

    Do you do you fan and noise measurements with 110V or 220V? That should make a difference in this case at least.

    115V but I also take noise measurements with 230V because of Cybenetics.

    115V: 23.25 dB(A)
    230V: 23.29 dB(A)

    Specifically at what point does it change from passive to active cooling using either 110V or 220V?
