No software can read the power consumption, especially not of every component. Hard drives and most add on cards have no accurate way of measuring or even guestimating their own power consumption since it is usually insignificant. Graphics cards and CPUs guess based off of the voltage level the chip is set to but that doesn't account for inefficiencies in the VRMs and the actual usage level of the processor which both affect its power consumption.
Software is totally inadequate for accurate power measurements, if you find software that claims it is I bet you my SWAGs are more reliable than it. If you want to know your power consumption either buy a kill-a-watt, guess, or get a current clamp to measure the flow through the wires feeding each component.
Software is merely a guess due to variations in hardware.
there is no software that can do this reliably. personally id use a clamp meter but considering the cost i assume a kill-a-watt meter would work better but im only guessing as ive never bothered using them
