If it does, thats sure as hell not the real picture. That thing has to be much bigger.

balanula, i try to be nice to people on the forums as it is how i want to be treated, but you posts push the limits of my patients. Why are you always trying to find fault and start controversy? Are you unhappy that you didn't buy a single sooner?

He's been that way forever. I just ignore him.

Unless you bought them at 25k/ea.

Now that's a good price! Breakeven in 5 months. That's incredible if they can deliver it... it will breakeven before the mining rewards drop to 25btc.

Ok folks, I have some good news with regards to the power requirements for the RigBox.  According to "People Familiar with the Matter" (TM) - the RigBox will use dual 1500w PSUs, meaning they will be 120v/220v switchable units... also meaning you can plug, (presumably) each PSU into a separate circuit to prevent overloading one circuit with impossible current draw.

That's awesome. Inaba, you should as the people in the know if they've thought about splitting the rigbox into 2 devices then? Sell them for $15,000 each, mining 25.2 Ghash/s for 1250W. That would make more sense, right? Send 2 of these devices to the people that ordered a big rig already. Or would they not be able to achieve those specs then?

Well ... actually ... the original faulty estimate was 20W per 1GH/s
That, as everyone knows, blew up to 80W for 832Mh/s (if you ignore Inaba's results except the very best one he got)

The web site now says 50.4GH/s @ 2,500w

Doing a simple 50.4/0.832 x 80W gives 4846W so we are talking almost a halving of the power requirements ... and an 18% reduction in price.
That's gonna be interesting.

The RigBox power spec was calculated after what we learned from singles. So the increased power has
already been taken into consideration...


Good Luck,

Implying you don't have a working unit?

They are not the same cards in the RigBox as are shipping in the singles.

Well that's an even better price reduction Smiley

Yeah. I know how PSU works ( if you have 1200 W PSU it does not pull all the 1200 but only how much you need ) but the sign that a bigger PSU is needed means that the power consumption was AGAIN underestimated and will probably end up being close to 3000 W.

The good news : it can work in the US.

The bad news : it is now 3000 W or needs that big a PSU for stable operation Shocked & still no concrete details about dates or chips etc.

No, not necessarily - the extra 500 W could simply be headroom.

Umm.. yeah.  Stop trying to look for faults where none exist.  Two 1500w PSUs are the only option for powering 2500w.  You wouldn't want to run two 1400w units (or 1300w) because they'd be at or near 100% capacity 24/7.  You want your PSU's to run at 60 - 80% capacity.  If you knew anything about PSU's, you'd already know this.

No, it's because there aren't any 2500 watt PSUs at a reasonable price, and it is cheaper to gang together 2 1500 watt units. Sheesh.

Ok folks, I have some good news with regards to the power requirements for the RigBox.  According to "People Familiar with the Matter" (TM) - the RigBox will use dual 1500w PSUs, meaning they will be 120v/220v switchable units... also meaning you can plug, (presumably) each PSU into a separate circuit to prevent overloading one circuit with impossible current draw.

This also means, I presume, that each PSU will be field replaceable by the end user without too much hassle and downtime.

This pleases me a great deal.


I'm glad they did this. Saves me a couple grand.

Since we've had so many questions about Order dates and Ship dates I've created a thread for just that information.

https://bitcointalksearch.org/topic/bfl-single-order-dateship-date-67887

By that information, most people who have received product, could have purchased a 5970 ($450?) with that money and paid half of it off with average electricity prices.  Three month delivery time with money paid up front really hurts the payback.
