(here in the UK we have 220-240v mains...and it took out everything except the drives)
I'm sure it did. Flipping to 110V switches the bridge rectifier to a voltage doubler which means bye bye primary side capacitors.

Friend of mine lives in the boonies and used to have PSUs die all the time, sometimes within months of purchase. One of them left scorch marks on his wall behind the computer. AFAIK none of them ever took out hardware with them.

His problems went away after purchasing a line conditioner, and since then he's only had to replace his PSU when he needed more power, not because it died.

Ways to set your power supply on fire...

-Flamethrower
-Bake (at high temperatures. It seems obvious)
-Faulty Power Supply makes it set on fire
-Old, Crappy Power Supply on high use
-over-voltage (over 240V but I doubt anywhere has that unless you connect it to a car and turn it on)
-Explosives!!!!!!

If there's no overcurrent protection or crappy transient filters, then yes the switching transistors or diode bridge could get screwed over pretty hard. If there's enough current, they could literally explode.
