I got one of the Jalapenos in the 2nd small batch sent out after the first 2 Jalapenos - so well before him.
Mine reads 32W at the wall (5.4Gh/s)

How hard is it to misread a kill-a-watt? Perhaps it is a multi-chip unit with the chips under-clocked.

Clearly for the guy at Ars - misreading a kill-a-watt is pretty easy.

Mine is a multi chip (2) unit (30 cores) that is under-clocked.

Any options as far as overclocking go? And any news posted about the temperature it runs at?

No clocking control.
Mine runs at around 46C +/- 2ish ... 5.4+GH/s ... 32W

But seriously - the guy considers himself worth giving a report and he comes up with 50W
Sounds more like "Oh I just looked at it sideways and misread it - but does it really matter I'm within 80% of the actual value ..."

He's certainly on the list of people I'd take no notice of anything he says.

... and 50W is 'slightly' higher than 43.5W? Seriously?

Basically it all means his Kill-A-Watt is screwed (50W ... 43.5W ?!?) and he needs to have a reliable one before reporting ... but hell, why would anyone expect reliable info from someone reporting something ...

Perhaps his BFL unit is internally damaged and its "messing around" with its own power usages due to a faulty component?

As far as wanting to read the kill-a-watt, wired just posted the full image with their review, reading 43.5, meaning a sightly higher reading around 50 may well just be current inter-unit variability. Future variability is anyone's guess though.

They don't update here anymore? Just advertise?

My impression is that they're sorting out the chips that ended up lower speed than predicted and trying to figure out how to ship everyone their units without having to pay out the ass for their number error. Then they'll start selling the new, slightly slower, much more expensive units.

The new power draw figures aren't out yet (probably in case they have to change again) but it looks like the 5GH/s jalapeno is going to be 30w per the last thing I saw. For reference the new units support up to 16 chips on one board with higher power draw overall.

Klondike.... 16 avalon chips 4.512 GH/s @ 32 watts. Hmmm funny if they work and the start mining en masse by August. I'd be pissed if that happens and I was a BFL customer waiting at the end of the queue.

It be nice to see a Garzik like review of any of these "prototypes" that BFL shipped. Funny none have been given a real review. I wonder why?

It looked like the Ars Technial jalapeno was 50W... seems like there is still some inconsistency to the models being shipped currently.

Again, I expect the guy can't measure power properly.
He's the only one with 50W - so unless there is something wrong with his Jalapeno, it's simply a case of using a crappy Watt meter or not being able to read.

While very possible it could also be the difference between measured at the wall and expected/drawn by each chip (although I would doubt a 40% power waste). Some of what they had mentioned about changes to the metal layer on later batches of chips (read also: not the ones shipping now) is that the later chips had improved power profiles. So these might be the early chips that eat more power. He may just have a bad unit or bad measurement, or there might be higher variability and/or power draw in the first units.

TL;DR - I would at least expect later units to draw less J/GH/s
