The +12V rail's 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 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.
