Bad cables or bad mobo?

Installed some new Cablemod modular PSU cables for my Corsair SF600 yesterday and used my computer just fine all day. Went to turn it on today and no noise, fan movement, any signs of life when I push the power button. Appropriate voltages getting to appropriate pins on the cables when checked with a voltmeter. Breadboarding to bare minimum didn't help. This smells like my mobo randomly died but are the new cables truly just a coincidence? It seems like the community has a lot of confidence in Cablemod but anyone have problems with them? What are the chances this is due to the cables vs mobo just died? I don't have any other known working components to sub to check. Thanks!
