On the wall, my pc use like 350w-400w when gaming and 120w-150w when browsing the internet.
I game like 16h/week and browsing the internet for like 24h/week
With a quick maff which is probably wrong..
((375x16x4)+(135x24x4)+(375x4)+(135x6))/1000 = 39.27 kWh
If i input that into the calculator, it show the monthly bill for my whole PC = RM 7.77 or USD 1.64 or EU 1.66 or CAD 2.44
