I have AMD athlon II x3 450 processor, ASRock N68C-S UCC mainboard, 2 sticks of 2GB DDR3 SDRAM , 1HDD 5400 rpm Hard Drive. Now i have Geforce GT 520. I ran psu calculator and it said that around 330w are recommended, but it is written in the GTX 650 Ti BOOST specification that 450w is minimum and my friends says that the psu i got will not be enough.
This is my power supply unit
