Intel Core 2 Chipset Power Consumption Shootout

Gaming Performance & Power Usage with Oblivion
Once again we see unusually low performance from Intel's 975X chipset, while the P965 and nForce 570 SLI are virtually equals.
Power consumption is fairly similar to what we've seen in the past two benchmarks, with the 570 SLI pulling 5.8% more power than the P965.
With better performance and lower power consumption, the Intel P965 continues to be the performance per watt king.
Turning up the resolution equalizes performance:
...while not doing much for the power consumption standings.

Whoops. Intuitive logic doesn't always pay off. See the following chart which gives energy costs/BTU for 2006: http://www.npga.org/i4a/pages/index.cfm?pageid=914">DOE Energy Costs . You can see that energy cost from electricity is almost double that of natural gas. You may help heat the building, but it will cost you more. And remember that a lot of electricity comes from coal fired power plants (CO2 producing) and every wire consumes it's own share of energy released as useless heat. Ok probably too much off the chipset topic, sorry.DigitalFreak - Thursday, October 12, 2006 - link
Quick, call Al Gore!Thanks for the good laugh.

10w is not all that inconsiderable, look at it over multiple components and it becomes significant.10w just for the mobo is, IMO, quite a chunk.

Could you measure the power draw of just the chipset by increasing the voltage of the northbridge by 0.2V and then re-running the tests? Take the difference between +0.2V and normal and then you would have isolated the power draw for the chipset and can work out the power draw for the chipset alone.
