Power consumption advice please

Firstly, does the GTX 260 216 core draw about 42w?

I ask, because I am trying to drill down the power consumption for my machine. With the computer sat normal in the BIOS, about 137w is consumed. With the graphic card removed, this plummets to around 95w. This gives me my 42w figure for the GTX 260.

Sat at Windows 7 desktop, 5 minutes after startup and everything has settled/loaded, the power consumption is about 112w.

I can account for 15w being used for two harddrives and two optical drives consume a total of 5w.

Which leads me to the question, where is the other 75w going to? The CPU and RAM?

Have you looked at this at all?

What about the manufacture's website? It should give you specs there.

Remember that your power supply isn't 100% efficient. The amount being drawn at the wall isn't the same as what your components are actually consuming.

A GTX 260 will use a good chunk of power even at idle. 42W sounds fine, pushing 200W + during gaming

IIRC, a the maximum draw of a GTX 650 is about 110w for the same, or slightly better, performance of my GTX 260. Idle power draw is about 5-10w. Saving at least 32w.
