More than you need to know here David http://en.wikipedia.org/wiki/Switched-mode_power_supply
But I'm not surprised that you dont get an ohmic reading. AC, according to above, goes straight into a half wave rect or voltage double for 120V operation, probably with auto switching. So dont worry 'til the cap doesnt work.
I did work at one time on DC SMPSUs and they were a B when they blew! took out semiconductors all over the place.
