Can we consider the Power consumption feature in Everest as a trusted source?
It shows that my e5200 draws 7w at 264x6 and max 29w at 264x12.5

Those numbers sound about right. I'm not sure what technology Everest uses to make those measurements, so I don't know how accurate the numbers are. However, they're probably good enough to compare processors.

thanks

Everest uses data reported by the ISEN pin of the VRM.

So if it reports 32A, and the Voltage is 1.2 then we have 38Watts. what cpuz shows is not to be trusted.

ep45-ds3 board, 450Vx psu

I had 28 watts on E5200 @ 2800Mhz 1.18V while running intelburntest
that being 120 watts total system consumption, 87watts Idle.

120 * 0.83 = 99.6 Watts (83% psu efficiency)
87 * 0.82 = 71.34 (82% psu efficiency)

99.6-71.4=28.2 watts, that seems ok for cpu alone, but while running intelburn other parts of the system like NB and memory are being stressed.

-38W 3200 Mhz 1.28V. and less than 3Watts while Idling.

Now I have E8400 3600 @ 1.18 and 41 Watts intelburn test,
137watts total system and 87watts idle.

137 * 0.83 = 113.71 watts

113.7 - 71.4 = 42.3, seems ok

your calculus is right and is consistent with my data under IBT (1.13 volts here).

Sisoft Sandra shows something like 25w for Chipset/Memory, even if I have no idea on how it gets these values.

This should lead to a THEORIC 124w under FULL load
55w undervolted 3850 256mb (63w@def for a table found here),
29w cpu,
25w p43/ram (23w non oc'ed for ixbtalbs),
10w for hdd and various stuff.

6550gp v2.0 has a 80% power efficiency, so 150w are supposed to be drawn under intel burn test+a theoric 3d intensive app.
Unfortunately I haven't a power meter atm, but I don't think that these values are wrong, aren't they?.

For IDLE:
cpu about 7w
p43 9w for ixbtlabs
3850 10w undervolted (14w@def for a table found here)
hdd+stuff something like 10w

36w and 80%eff=43w
This one seems too low for me, I have read that this kind of rig should lead to 90 100w in idle...
Am I missing....what?

What version of Everest does this tool come in?

latest

No, I meant Home vs. Corporate vs. Ultimate.

ah
Ultimate

efficiency should be as low as 60-70% idle

comparing again with Ibt running. both have the same consumption everest shows 25W and total system is 118watts.

e5200 @ 1.25V(1.18V) 2.8Ghz and
e8400 @ 1.10V(1.02V) 3.2Ghz,

wow sounds good... and 3.2gig at 1.02v means a very lucky cpu.
What about idle? Do my values sound weird to you?

Not weird at all, undervolting the vga, nice. I have seen everest show some modern GPU's power too.



idle is nonexistent, everything below 2.66 watts is not shown.

that gpu vcc is wrong
