So please do not use an " announced " chip power consumption number to compare with a full system power consumption number, it's meaning less.

It would be nice if all vendors published the full power consumption figures for their stand alone units.

Will people in countries with 240 AC supply have a slight advantage in terms of power consumption?

Yes. But only after others have a working device.

19.5w -> 80w

Did I tell you to shut up?

BFL can plug into a OpenWRT device LIKE one in AVALON. Even an Android phone would work.

Your question is does Raspberry Pi gonna have enough bandwidth as a host? Fck yes, it also shows you know crap about this.

Avalon engineered the OpenWRT solution to work effectively.

I don't know what they had to do to make that happen, but I know that you can get away with using a low computer power single purpose device if well engineered to the application.

Everyone in this thread seems to be suggesting the end consumer should slap some 5W toy device called a "Raspberry Pi" into their BFL miner. My experience tells me this is not a real solution.

What operating system and mining software should they install on it? What optimizations should they perform on the OS build to ensure the bitcoin miner is not interrupted by other processes?

If BFL isn't going to provide a mining controller, then most users will end up using a real computer, not a "Raspberry Pi." You should be more realistic.

Any system needs to pay these extra power, including BFL.

I'm tempted to agree with you. However, I do still stand by the fact that the total system wattage should be stated on the sales site, not the wattage of the chips. It's as simple as it being misleading.

Oh hey, and here I was thinking this was an Avalon ASIC user's thread... But Nemesis here seems to not get the subtleties of the thread title between namecalling and cursing.

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.

No, I think it's nothing to do with the host PC.

To power the chips, we must convert 220vAC to 1.2v DC. And we must shift all heat out. This process cause power loses.

Any system needs to pay these extra power, including BFL.

Will a "Raspberry Pi" (whatever that is) going to have the bandwidth to handle difficulty 1 mining from a 60GH/s device. I doubt it. So the power consuption for a "Raspberry Pi" is pretty irrelevant as well.

Idiot, do you know the spec of the host board of Avalon?

You should shut up now, you might learn a thing or two....

What's the point of talking about something that doesn't come with the device?

I know BFL has a thing with physically attaching unrelated consumer hardware to its mining equipment, but design does not transfer by Osmosis. If I glue an IPad to my Bitcoin miner it doesn't mean my Bitcoin miner becomes a well designed and intuitive device.

Just reminding everybody...you shouldn't compare the power consumption of a product that actually exists vs one that doesn't.

Avalon gets you more than 1 GH/s per 10 watts of power @ 120v. Good luck beating that with what currently exists.

You should probably put the 620 watt figure on your website so that people are clear about the amount of power the whole unit consumes.

I completely agree, the website currently indicates the total system wattage is 450w.

I'd like to point out that the power usage for this unit is economically irrelevant, and not really necessary for discussion.

The statistic that matters most is time -- Avalon released first, so they win. That's really all there is to it.

Chip's power consumption is <6.6W/Ghs

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

So…

I see. Makes sense then. Thanks for the clear-up.

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.

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.
