CPU for video encoding

It's full system power draw,at the wall. FX8150 is 125W rated CPU.
As for 2pass question here is the faq:

Mode:

Description: Selects the encoding mode to be used by the encoder. Single pass encoding can give unexpected output file sizes (Quantizer and Quality modes) and/or poorer quality compared to multi pass encoding.
Available Options:
Single Pass - Bitrate: Encodes the video once (single pass) with a set constant bitrate for each frame
Single Pass - Quantizer: Single pass encoding with a set quantizer (higher quantizer => lower quality) for each frame
Single Pass - Quality: Single pass encoding with a set quality rating for each frame
Two Pass: Encodes the video twice (once to determine it's properties, another to ensure the selected output file size is reached with maximum efficiency). This is the most common setting.
Three Pass: Same as Two Pass except for an extra encoding pass to ensure even better quality/accurate file size
Command Line: --bitrate, --qp, --crf, --pass 1/2/3

As you can see(underlined),2pass is listed as the most common setting. Emphasis is not mine. Single pass is clearly (as per their definition) inferior way.

Also, who does two pass encoding?

Anyone and everyone who cares about maximizing IQ while minimizing the bit-rate.

I haven't done single-pass encoding in over 10yrs. I don't know a single person in real-life who doesn't encode with 2-pass encoding.

So I'm personally curious about the counter-question: who doesn't do two-pass encoding?

I didn't see any mention if that being draw at the wall.

Constant quality vs 2 pass.
I use handbrake, to me it is not worth encoding the save video twice, but your time is your time.

So how did the tester get the 8150 to pull 199 watts, is that accurate?

That's system power consumption, meaning the entire platform, not just the CPU.
