| Watts in TDP are not the same as watts in electricity, although they're both measures of energy. TDP is a thermal measurement, it's how much heat energy your heatsink and fan need to be able to dissipate to keep the unit within operational temperatures. It does not directly correlate to the amount of electricity consumed in operation. |

| PC power draw at the wall is different than TDP. Idle power goes to a lot of components. Even CPU TDP is not an accurate measure. My latest AMD CPU will pull more than it’s rated “TDP” under certain loads. |

| In the UK, residential electricity tariffs are currently capped by the regulator at 27.69p per kWh, resulting in a total yearly cost of £72.77. Much higher than in the US, but still much cheaper than a new PC. |

| So $50/yr for 4 years gives you ~$150 with $50 extra for shipping or whatever, which gets you a decent Lenovo M700 Tiny with much better performance in both power and power consumption. |

It's hardly an open-and-shut case of "throw your old computer away!" though, especially when this is a worst-case scenario of running a desktop computer at full blast 24/7 without it ever going into sleep mode or being turned off, and when you don't know what the user's needs are. Maybe a mini-PC with basically no expansion just won't really work for them? |
