When quoting BFL's numbers, no one includes the PC it's hooked up to either.

+1, a fair perspective





Fair perspective? amusing indeed.

You're really gonna site a 5W overhead? The fact is this thing uses 10x the amount of power, and they were dishonest by not warning anyone.

Chip's power consumption is <6.6W/Ghs

ATX power loses(82%), DC/DC power loses(87%), Fan(5~20w), etc…

So…

Dear Dr. NGZHANG,

That's not the reason for you to claim the power consumption of the unit is 450w.

The power consumption of the unit is what all it matters. You picked on BFL for the same thing and now you talked like its all fine and dandy.

LOL at ... saying fans power and all that. Should I add the power I need to cool my room?

Yes, but those losses and loads were part of your power budget for 400 watts, correct? Don't be like Josh-- you were expecting less than 6.6 W/GH/s. Simulating the power performance of a chip like this is a lot more difficult problem than calculating how many watts you will need for the fans. Its completely understandable the simulations were slightly off, but still on the same order.

Couldn't you gain about 10-15% efficiency from the power supply using 220v instead of 110v at least with the power supply?

ATX power loses(82%), DC/DC power loses(87%), Fan(5~20w), etc…
Not sure it would benefit any of the other numbers?

A Raspberry Pi definitely doesn't pull 200w though and you can hook the BFL stuff up to any low power board with USB connectivity...

thanks for clearing that up ngzhang.

Makes sense as it's a stand alone unit.  When quoting BFL's numbers, no one includes the PC it's hooked up to either.

620 Watts is quite a ways off the 400 Watts Yifu kept insisting on... Jeff, are you sure nothing's going haywire over there? Because I find it hard to believe a 50% larger power consumption is something they would've missed during development. Hell, it's even a tad over the maximum possible power draw they announced back in the day and they specifically mentioned that electricity consumption is lower than they initially estimated, bringing it at 400W.

[EDIT] I see Yifu updated the power consumption at 450W, but it's still a far cry from the 620 Jeff reported. So which is it?

My questions are mainly of shipping:
- Did you have to sign for the shipment (was it registrered/insured)?
- Did the machine clear off to customs, or was it taxed?

And do you remember how much shipping was when you ordered it last year?

Jeff's machine got special shipping because it was intended to arrive on a specific day.  Avalon said towards the end of January that shipping the units was going to cost more than they thought so it may well be more than they charged for batch 1. This may be another reason why they're so keen on resellers entering the game.

60,- USD if I recall correct.

Power numbers snapshot:

     620 Watts, 5.6 Amps

thanks to Kill-A-Watt.
200+W per unit? Holy balls. That's a hell of a lot more than 400W.
Looking at the images from the Bitcoin Federation unit, it looks like they're using the 1000W Platinum unit.
Compare the sides on the 850W PSU

vs the sides on the 1000W

http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story&reid=270

Looks like they might need it to run 4 modules.

Ouch.
I sure hope they deliver to Australia quickly... because I have a feeling I won't be running my Avalon for long.
I'll probably find a use for the case and sell off the modules to someone who has cheap elec :/

Thanks Jeff. That makes a big difference to the earnings potential in the long run - but probably not for the next batch, unless BFL manage to deliver.

That is not 400W :\ I think I might be reconsidering my purchases from batch 2 now.

Thanks for taking the time to write the review and take the readings Jeff Smiley

Even at the US$0.25/kWh, $20 USD/btc and difficulty = 6 million (after 300 Avalon units have been added) you'll still clear US$108 per day.

If BFL ships another 40Ghps and diificulty = 12 million, you'll still clear US$52 per day. You should still be able to make an ROI if the exchange rates hold. I'll try to post something quick about the limits of profitability later.
