Question can the cx600 run 2060 super

If you are considering a $400 graphics card, you should consider a $100 PSU. Don't drive a Corvette on donut spares.

If it's a CX600 (as opposed to a CX650), it's old, double forward, no DC to DC, has a sleeve bearing fan and only rated to operate up to 30°C. It's actually a miracle you have one that's still functioning at all.
