A few days ago my Thermaltake TR2 600w power supply was damaged, since that day I have been finding out prices on power sources at my location. I have not had much success because I do not live in the United States and there is no great variety of psu. My budget does not reach $ 100 and the sources I have been able to get are the following:

-Corsair VS650 600w black and gray model
-Thermaltake Smart Series 500w
-Evga White series500w

I've been reading good and bad reviews about the VS series of corsair, and those of thermaltake and evga, but I'm not sure which one to choose, or which one could be better psu below $ 100

The specifications of my pc:

I7-3770 3.4GHz
8Gb Ram Corsair DDR3 1333mhz
Nvidia GTX 750TI 2GB FTW
Asus P8Z77-V-LX
Hard Disk Western Digital Blue 1TB 7200rpm

The computer has a fairly long use on the day either programming web development and playing "current games".

What PSU is the best?
