Core i7/X58 Overclocking Thread

[GenTarkin]

I finally got ahold of a kill a watt and measured my OC power numbers =)
Very interesting to say...and system not using anywhere near what I thought it would.
My major hardware is listed in my signature.
Here are my readings 3822mhz @ 1.27v 182x21 VTT/QPI@ 1.25v 3095mhz .. all other voltages on auto:
Computer off but plugged into wall: 2watts
POST to windows an average of 160-190watts
Windows idle:160-175watts
WCG number crunching: 290-300watts
WCG+3dmark06: 370-395watts
3dmark06 only: 260-290watts
Prime95 blend: 307watts
CoreDamage: 325watts

Now the next point is...the PSU effeciency is rated @ 80+. I am not even using its full load capacity meaning its more likely less effecient then that. So, assuming 75% effeciency...is it correct to take 25% off the above numbers and that number is the true power draw of my PC? (obviously I know the socket sees the full numbers listed above, but Im talkin internal usage after the effeciency of the PSU is taken into affect...)
