What happens when you push a good quality PSU to the limit?

What are some things that may happen if I crossfire a 290X or any other power hungry card/s and use it underload with this PSU

The only things I know so far are:

-Instant system shutdown

-Blow a component in the PSU

-Game/Program crash

good psu = pc shuts down

bad psu = psu rips

If youll draw more power than it can take, it will just shutdown. If you were using crappy PSU, you might kill it and kill some other component too but in this case I wouldnt worry.

A good power supply should be able to constantly output its rated power and be able to handle surges higher than its rated power. Extended overload will shut down. I have found that the cheapies are generally rated at what wattage the thing will detonate at.

We really should be able to tick more than 1 reputation icon.  I had a hard time choosing between "agree" and "funny".

I see thanks for the input everyone.

Had a crappy psu blow on me once. Opened it and found caps blown and resistors melted. Lucky the magic electrocity pixie's did not blow my other components and release the mysterious blue smoke.
