Ah ok. Yes, that's true, you can customize MSR[...]62 to switch P-State manually without CnQ.
You don't need to disable CnQ in BIOS though, just change Power Options to Max battery and try in Windows.

I haven't tried checking CnQ settings load watts. [added below]

Scripts don't work for me still. Debugging doesn't get far. RWE just freezes and you have to use Task Manager to kill it. Will need more time for it.

Your 1st power figures (2600) should read AC / DC.. you missed that but edit comes handy

You'll need more than 1.312V for 2600 P95 stable it seems. I'll update mine to a similar setup and then try and compare power consumption and work out why the difference. I'll use your volts and settings. I'll do it on this now and then with the Sapphire when I get hold of one (should be soon).

115V: PSU is 78.5% eff. at 110W AC and 81% eff. at 156-186W AC.
220V: PSU is 80.6% eff. at 110W AC and 84.3% eff. at 156-186W AC.

I'm going to pick up the Gigabyte GE-S550A-D1 PSU soon and use it's P-Tuner software which is pretty damn accurate (known problem is +25W DC showing and 12V3+ below 180W DC is wrong) to show me the amps/volts each rail is pulling and work out the DC power draw by the CPU 8-pin.

So we'll know what the CPU is actually pulling alone and I'll put the GPU/MB/peripherals on separate 12V rails so we can work their draw out too.

The attachment linked worked before but doesn't now
Attached it again anyway.

EDIT:
I just tried everything again, found a bug in CnQ. Good news.
