Now that I look, my previous power supply was also an Antec, the EA-500 Earth thing, 500 W with a dual 12V , 17A on each rail. Did this thing blow because I was using too much power with the above setup or was it just its time to go after 2 and a half years?
I would say that your video card catching on fire had a very good hand in ruining your power supply.
Try to download HWmonitor: http://www.cpuid.com/softwares/hwmonitor.html
and keep an eye on video card temperatures from now on.
Add in a case fan or two if needed also.
