Bad motherboard? Or bad psu?

Recently bought a 700watt semimodular pau from someone I knew and he verified it worked before selling it too me. I go home and replace it with my corsair 600watt so I can run 760s in SLI. I put everything in place and. Itching works. Nothing turns on. Once in a while the corsair liquid coolers light flicks on for a split second. The light my room also flickers once in a while. I tried my old psu without the other 76 on there and it isn't working. I'm sure all wires are on correctly. Is my motherboard dead? There was also a little burning smell from the corsair psu when I tried to install it back.
