is it possible/common for a PSU to fry a mobo? With no visible damage that is, just not switch on/power up.

I know this may sound obvious, but if your power supply is fried, you can't turn on your motherboard :)  try switching out power supplies.

Also, yes it is possible for a bad power supply to burn out a motherboard. That's why it is always beneficial to buy quality power supplies, just to be safe, ** Antec, Enermax, Fortron, etc..

It is certain that this can occur. It is also possible on older boards / psu's that you can fry components plugged into the mobo based on any voltage protection schemes / lack thereof. When my PSU went out on an old computer of mine it also took a hard drive with it(the mobo) somehow. Unfortunately I had to have a shop test all my components before putting all my old crap back onto a new mobo. I just ordered a new system (parts of) and the power supply was something I had to spend more than I would have previously thought for a good one. It'll be well worth the extra money.

Um, mine was a normal, working PSU (5 years, 2 Mobos). Generic though. At one moment though my Mobo mysteriously stops powering up (at all - fans etc.) even with another psu. Now plugged in another mobo, power on does half a revolution (fan) and no more. Hope it didn't fry the second one. CPU seems also fried on the first one. Is that possible (Asus A7V KT133 - the old one with the seperate ATA 100)
