Sonny allowed me to convert my rig box order to two mini-rigs. That should work better for me since I can split the two into separate corporate data centers and avoid straining the A/C unit in just one data center.

As a side note, I plan to monitor my electricity usage and "pay back" my employer by using my personal credit card for an appropriate amount of IT purchases each month.

I wonder if adding 10% or 20% to the $.095/KWh would be sufficient for the extra A/C usage...

Well - that would imply the mini-rig is not a concept but a product you can order?!?

Lemme guess 10-12 weeks Wink

I did find some nice atx style redundant DC units - if it just has a standard atx we should be in business.

I'd be interested in what you found. As you noted, the conversions back and forth between AC and DC have fairly substantial losses, but I have never been able to find a cost effective DC-DC converter. I have an extremely powerful 48VDC power source, and that would be perfect if I could find sufficiently powerful DC-DC converter that doesn't cost too much.

Hmm. I think I misread the output power on what I was looking at last night. I'm not finding a big enough atx unit for this application, though, that's not the only way to skin the cat, and I'm sure I overlooked something.

I got confirmation on my order from Sonny today, and asked if he'd look into this possibility for me.

Here's a few links. I can't vouch for the quality of the products below. Most of these are more applicable to folks with larger mining ops.

Powerstream carries a few ATX items, but the biggest I found was 750w

Here are a couple others, more of a telco power distribution framework setup - for a rack full of mini or full rigs:

Yeah lets get back to the topic of mining.

BFL if you include a pony it better be a mining pony.

Obsolete by modern standards that PNY200 could mine 200 KC/D (kilo coals per day). Those were the days when mining was tough.

I'm not saying I disagree with you. Especially about the warranty... I agree that it should be 1 year. The reasoning for a 6 month warranty is sound, as given by BFL... but it's also just as sound as warrantying it for a year if you agree with the entire premise. So yeah, I agree.

The rest of the stuff, I also agree with, it's just been said a hundred times over already, which is what elicited the pony comment. Yes, we all want those things... and either we are getting them or not, but while we're wishing, lets wish for ponies!

Can we pleeeeeease get back on topic?

I'd like to read news about the Mini-Rig, no interest in ponies.

If they do include ponies you can be as cool as these guys ...

Inaba,

No thanks, not a big fun of the pony in the server room...

Do you know what is expected life time of these units? I don't understand why are you happy with the 6 month warranty. your device may die before you would see any profit from it...

The rest of the points maybe not important to you but i would like to see
a; improvement on the delivery time
b; thinking of costumers who want to ourder outside of USA.
c; see a modular design

i can see how a pony fits in with the list as a whole. i do however think a more respectable warranty for an expensive piece of hardware is a reasonable request.

This concept sounds good. I am interested to buy one of these.

Before that i would like to know:
- can we get at least 1 year warranty? The payback time of this is around 6 months (with the current exchange rate)
- can you ship from Europe? Custom would significantly increase the price of this unit.
- do you have a better delivery ETA? 12-15 weeks as it was projected in an e-mail would be too long...

Also, i would like to see a rack mountable design where we could push some extra cards for expansion.

If BFL could actually deliver products in 4-6 weeks they would be printing money Grin

The uncertainty of delivery is a major obstacle right now despite their very compelling ROI (so long as power costs are < $.20 Kwh).

If you guys decide to do this I will be ordering one as long as I can get a decent turn around. Might even take two as I have a few possible investors at this price. The best of all these are Co-Workers that are very possible investors.

hmm. in most case inversion has higher up front costs, and more transmission loss, so I'm still thinking we can do better by not introducing AC into the box at all.

It would be super sweet to be able to order one of these dc, or w/o ac power.

LOL & thanks!

I wasn't clear - by "this" , I meant the mini rig

the single is very straightforward.

In that case speculation only, since it only exists on paper.

If I were to go out on a limb, I might assume they are using a standard ATX PSU, which you may be able to replace with a properly sized DC-DC converter. But at such high wattage, it would not likely be cost effective. However, you might be able to drive it with 12v directly, in which case I would assume it to be between 1200 and 1400 watts DC.
