I need the specs on BFL power adapter.

Updated w/ specs as I know them.
Polarity: Center 12V
Inner diameter of barrel connector: 2.5mm
Outer diameter of barrel connector: 5.5mm
Barrel length: 12mm
Max DC amperage:  10A @ 12V (PSU is rated for 120W.  BFL care to comment on actual max DC load of a BFL Single)

Has BFL provided any specs?  
Anyone look on their Power Supply some or all of that might be listed?
Any photos of the PSU available?

On edit:
link to BFL post on physical specs:

 Grin I smell homebuilt BFL PSU's to be constructed.
I bet it's going to be really annoying in a cluster if you have so many little external power bricks..
It'd be cool to see a "BFL Cluster Powerbrick" with like.. 5-10 12v lines coming out of it, Could prolly save alot of money, And on shipping alone too

Yes but I don't think they will accept you to buy it without the PSU they are selling you Wink

Not selling you their PSU and not charging so much for shipping = less profit for them = unacceptable for BFL Cheesy

I smell a business opportunity for them here, supplying very high efficiency PSUs with modular cabling for clusters Grin

Photo of power brick in first post of giga.

https://bitcointalk.org/index.php?topic=65752.0

Also, these should be all the parts needed to build an adapter for ATX to BFL Single coax connection:

http://search.digikey.com/scripts/DkSearch/dksus.dll?vendor=0&keywords=CP3-002BH-ND

I just compiled these from the other post, I haven't ordered the parts, hoping someone more competent would want to do this.

Wonder if someone could contact Cablesaurus and ask him to make these? I might do it if I had the special Molex pin crimper, but the tool costs like $350 - just to crimp a few pins! Of course they could be crimped manually, but they would be much more time consuming and difficult to create.

I'm thinking about getting a Seasonic X1250 PSU, and just cutting off the ends of the PCI-E cables and the cables from the power bricks and splicing them together.  That would work, wouldn't it?

Some sort of pre-made adapter/cable would be great, though.

I was thinking of this PSU to run 11 singles -> http://www.newegg.com/Product/Product.aspx?Item=N82E16817814019

I really like the price at $170.

Single 12v rail
Active PFC
1100w
6x 6+2 PCIe connectors

11 singles at 83w each would be around 913w total.

Thoughts?

Should be fine as long as it can deliver the required amps on 12V rail.  Can't seem to find a spec sheet which shows 12V amp/watt rating.  It is a single rail design which is good as long just a question of enough 12V amps.

Closest thing I have seen in this photo of rating plate:
http://www.abs.com/Products/ProductDetail.aspx?ViewPage=2&ID=21

I can't make out the 12V wattage though.

Hmm, its cheap, but I see more than one DOA report on the first page of reviews (and 4 out of 5 eggs). Also, 83 watts includes current PSU inefficiencies, I bet it would be 75 watts or lower on the DC side. If I were you, I would protect my investment with a seasonic: http://www.newegg.com/Product/Product.aspx?Item=N82E16817151110

Also, with that parts list I posted earlier, you could probably actually run 3x singles per 6-pin connector - 1 per set of positive + negative wires.

I contacted a custom cable OEM on making PCIe to barrel adapters.  The only issue will be minimum order size.  My previous employer has use this OEM before so hopefully they will be willing to keep unit size down to 100 or so.  I got no intention buying 10,000 adapters. Smiley

I will be interested in 30+ if the price is reasonable.

If you're searching these lines for a point, you've probably missed it.  There was never anything there in the first place.

Says 84A@12v (1008W), so JUST!

Hopefully it pans out cause I for sure would buy 10+ minimum.

Would each adapter be designed for one, two or three singles?

I'd be interested in some, too.  Two mini-plugs per PCI-E adapter would be nice.
