SIPSurge: MOV Inrush: NTC thermistor & bypass relay

The OCP triggering points on the +12V rails are higher than Enermax's specs, as expected, with the 12V3 and 12V4 rails being over 50A. The minor rails are set at a normal level, according to our experience so far, while the 5VSB rail's OCP point is sky high at 7.1A! Nonetheless, it keeps its load regulation in spec, and ripple is also controlled well.

There is over-power protection, which works well. Over-temperature protection is also present.

As we've mentioned, the power-good signal is accurate. There is a short circuit with earth on all rails. And the NTC thermistor, responsible for inrush current protection, is supported by a bypass relay.

    The DFR would not be that bad at adding dust to the case if it does it each time you start your PC. If DFR kicks in each time you resume from sleep i do not expect to see dust all over the case but if DFR is only activated once or twice a year then yes you will be adding dust to the case assuming it actually detaches from the PSU.

    I'm afraid Teardown video is about thermaltake grand rgb.

    Yes there is a problem with the video. We are working on it! I am sorry for the confusion!

    As a side note, those two platforms share many similarities.

    I prefer to read the teardown analysis. I usually find that to be the most interesting part of the power supply reviews. Thanks for the high quality work that you do in putting these together.
