Is a 600W PSU sufficient to run two 7870s or should I consider upgrading?

Quality 600w will power those just fine :thumbup:

You need 2 -6 pin pci-e power connectors for each card.
Most 600 watts only have 2.
I'd upgrade to a psu that has the connectors to avoid adapters ,and take the doubt of are you powering things correctly ?, out of the equation. When it comes time for possible troubleshooting.
