Well, if you have a 1200w psu, that isn’t the issue…fully running you should pull around 900w-ish.

I believe I remember reading to make sure you have updated the bio’s to the latest version (which you said you did), TURN OFF 4g decoding!!, get each card installed and no errors in device manager, then turn 4g back on

you can see @cryptomined post [here](https://forum.zcashcommunity.com/t/msi-z270-pro-4g-decoding-enabled-problem/15921/11)
