You're right. When the PSU fails, it doesn't "fizzle". It's a definite "pop"."fizzle out," the article is being too nice to Corsair. I have bought one of the Corsair SF750. The PSU fails spectaculary. It makes random electric discharge in your computer case. It's as loud as hitting a table with a ruler. Basically your PSU turn into a tesla coil. For some users, it kills their computer.
I am currently going through a RMA. I don't know the extent of the damage yet. If you are in this situation, figure out who is the distributor and request the RMA claim form (mine was TIYU).
