The third 12V rail, which powers the PCIe connectors, has a higher triggering point than the other two.
Over-power protection (OPP) is set pretty high as well. Meanwhile, OTP kicks in at a lower temperature than we expected, although this didn't cause any problems during testing. The power-good signal is accurate, and there is short circuit protection on all rails.

2Be_or_Not2Be Nice - I really like how quiet these models are running.Reply
Of course, it's also funny that the Formula Gold model is less noisy on average than its "Whisper" mate.
