Dual Power supply best practices

[demet8]

I have an EVGA SuperNova 1200 P2 dual connected to an EVGA - 80 PLUS 600W ATX 12V/EPS 12V Power Supply. The EVGA SuperNova 1200 P2 is the main power supply and is connected to the cpu. Can I plug both power supplies into a surge protector & then plug the surge protector into the wall socket? or should I plug both power supplies into a separate wall socket (power source)? btw I have an 8 GPU rig running MSI 580 4GB graphics cards..Thank you.
