Thanks for suggestion.
I found that calculator, little inaccurate and read reviews before, which wasn't so good. It gives unreal recommendation power supply. due to which i am hesitating to published them on my thread. Otherwise it was a good platform to calculate power.
Only Great solution for calculating power is kill-A-Watt or similar meters. also i would like to mention here corsair link is one the software that digitally linked with power supplies which shows quite accurate results, but validate only for Corsair supplies such as AX 1200 and HX1200i and few other high ends.
Appreciate Your interest bro. keep in coming.
