    Cybenetics TPU :

    During the OPP (cold) evaluation, the PSU died, so I couldn't finish all tests. How did it die? I increased the load on all rails until the PSU shut down as it should. I left it to cool down and tried to restart it after five minutes, but was treated with fireworks and a loud bang. I had pushed its cheap primary switching FETs too far, so Gigabyte should lower the OPP and +12 V OCP triggering points.

    LTT:

    Further information

    The OCP is set at around 130%

    The main fets are 2x Jilin Sino-Microelectronics JCS18N50FH (500 V, 11 A @ 100 C, Rds (on): 0.27 ohm)

    The failure happened after the unit succesfully shut down on OPP/OCP, where it was turned on again after 5 minutes.

    The issue is likely caused by cheap main FETs, a too high set OPP/OCP, a design error or a combination of these.

    It does not affect the similarly named GP-APGM or any other Gigabyte units from what is currently known
