Will not start with both GTX 780's in place

Purchased R4 with dual GTX 780's with SLI. Ran fine for two years or so.

Computer will not reach BIOS with both video cards plugged in. I can use one card - either one of them - in either slot and all is fine. So - probably the cards are fine. My hunch is maybe replacing the power supply could work?

Anyone have this issue?
