Hello everyone, my first post I guess.

So the thing is, I have supernova g2 850w PSU. Everything worked fine until I decided to run some 3DMark benchmarks. First 2 run were good, but on the third one PC started crashing. Now it can't even boot without "Asus anti-surge was triggered to protect system from unstable power supply" message. The PSU is dying right?
The spec are:
I7-6700k
Asus Z170-WS
32GB RAM
5 SATA SSD
2x RX Vega 64 silver
Had this setup unchanged for almost a year now. Started having issues only after benchmark runs.

    Very possible, if you take out one of the Rx cards and test them one by one does this behavior remain ?

    Actually everytime I try to to power it on, it becomes more unstable. Now it crashes even with only iGPU on and those 2 removed.

    Maybe I damaged that PSU because it's not powerful enough. What PSU would I need to run this setup safely.

    ASUS Anti-Surge Support for Over Voltage Protection (OVP) and Under Voltage Protection (UVP) can be disabled in the Monitor section of the BIOS.

    ASUS Anti-Surge Support has been known to be kinda wonky and might be fixed by updating to the latest motherbord BIOS if needed, but almost always the error indicates a PSU problem..Many people have just disabled Anti-Surge Support and leave it that way if diabling it make the PC boot without coughing up the error and everything works fine otherwise.

    If you can boot into BIOS and disable Anti-Surge Support, then check the voltages (+12V, +5V and +3.3V) in the Monitor section and see if they fall withing Intel specs/tolerances..Using a digital voltmeter to check voltages would be best.
     
    The voltage tolerances specified by Intel are:
    +12V = 11.4 - 12.6
    +5V = 4.75 - 5.25
    +3.3V = 3.13 - 3.47
    -12V = 10.8 - 13.2
    +5VSB (Volts StandBy) = 4.75 - 5.25
     
    To estimate your sysyem wattage need, use the OuterVision PSU Calculator or the EVGA Power Meter..The OuterVision PSU Calculator is more advanced/detailed..If you use the EVGA Power Meter you'll receive a one-time 10% discount code (with conditions) in your email toward an EVGA unit purchased through the EVGA Store.
