> 102W is a /lot/ of power

Yeah, and OP was saying that was only the socket consumption, you've also got to add in chipset, memory, discrete GPU, hard drives, NIC, sound, etc... and power supply overhead as well.

I bet that system was pulling 400-500W total under the load he described.

A single old style light-bulb is not what most people think of as a lot of power and heat. https://www.1000bulbs.com/category/100-watt-standard-shape-l...

Further the delta is only like 60w under full load.
