•While the logic behind this myth seems plausible, the math doesn't add up. Let's do the sums. Using the Dell example above, if we assume the average desktop is drawing 89 watts per hour and is left in active mode overnight for 16 hours, the desktop consumes 1.42 kilowatts (kW) overnight. For this myth to hold true, the power surge of turning on your PC would have to also draw 1.42 kW. But since the power surge only lasts, say, five minutes maximum, this would mean you would be drawing energy at a rate of 17 kilowatts per hour (kWh) — the equivalent of 44 HP DL580 servers at 100% utilization. Moreover, the average US wall outlet can only provide 1.8 kW of draw, which is about one-tenth of what the power surge would require.
