Please give me the minimum and recommended requirement PSU for this config -
CPU : intel i5 2400
GPU : ATI 7850
RAM : 4GBx2 DDR3
*NO OVERCLOCKING WILL BE DONE*
People tell me not to buy "thermaltake lightpower" and go for "smart". Why is that? What's the difference? "Lightpowers" costs less for more watts. So, why not buy a "lightpower" with more watt than buying a "smart" with less watt?
Please do not refer to a PSU calculator.
