Turns out the Corsair AX1200 though it has enough power, it does not have the right cabling. New Corsair RM1000x solved the issue. :cool:
Strange... I have an AX1200i on my system and two RTX 2080 Ti's Not had any issues with posting in regards of the Omega.
Not suprised. AX1200i will have different outputs than my older AX1200 (no "i").
