Yes, like the others before, I too feel that you should be ok. I've had a power supply go boom on me several years ago and it sizzled and sputtered and let off a really bad smelling smoke, but other than scare the crap outta me, there was no other damage to my system.
I've also been given a PSU set to 110V by default (when it should have been 220V for India) and had that explode the second I powered-up, but once again no damage other than a big scare.
So...all the best. Hope your system is ok.
