I wanted to know whether we can approximate the power consumption of the PC if we have 1> sum of peak power consumption of all PC components in Watts (P) 2> machine uptime (T) 3> Avg CPU usage (Pcpu - a number between 0 and 1) 4> Power supply power factor (PF - a number between 0 and 1) I have formulated this equation. Please verify i...
