    Of course we do. How else do you think we measure input voltage and current?

    My E650 does NOT save the OCP config, never, in any situation. Every time that I power on the PC, there is no 12V OCP even if I had activated it previously. I don't know if it's a problem of my unit or a firmware issue. Also, there is no fan hysteresis configuration, which makes on/off loops very common if you use a semi-passive mode...

    You have mains control stuff in the MCU??
    That's what I was thinking about...

    So to measure input voltage you need something to measure it on the primary side and report it back with an isolated device like an opto coupler for example. Or measure it on the primary and report that to the MCU with an Optocoupler for example.
    Since its already measured (well, the current at least, for OPP), it should be possible...

    As I knew, the reading of input voltage on Corsair Link for RMi is not a real monitoring,,,,but just a detection. the reading of input voltage is fixed at 115v for RM650i.

    Hi, This is Elun from NZXT. you are correct, we did not provide the feature for saving OCP trigger point on our E series PSU. That is because we are afraid that if the setting is too low to cause the shutdown/failure when the system boots up. Actually, E series PSU is the first one in the worldwide to release the OCP setting by CPU and GPU respectively to the users. We will continue improving our features on our CAM for E series PSU.

    I'm pretty sure Corsair's RMi, HXi and AXi already give you that option and have been around much longer than the E-Series
    Just some nerd from 'Straya

    Yeah, all AXi, HXi and RMi series from Corsair are designed with OCP setting and(or) single/multi rails switching. However, Corsair's design is based on the EPS/PCIe connectors for its OCP setting.

    In the other hand, our approach on E series are focused on "User Friendly". NZXT wants to provide a more easy-to-use implementation on the protection for the expensive components, to the varieties of GPU and CPU. Different GPU and CPU have very various electrical performance on its peak current and wattage, we believed users should have the rights to define the how the protection enabled.

    So when you have a short, the 12V OCP gets triggered the PSU and therefore the PC does a shutdown. Then if you try to boot the PC again (which everyone will do of course) the OCP's on the 12V are actually disabled?

    Yeah, that's a bit unfortunate. You should work on that...
    For the "what if it doesn't work", you could use a Reset Button that resets the settings...
