if we buy the psu's from bASIC's website would we need custom cables?

Thanks very much for the kudos benny32, I am glad the cables are working well for you.
I just want to post that the transaction was quick and flawless on benny's side as well. +1 trader!!

Just wanted to leave some feedback here for Cablez. I got my four cables and 24pin switch in the mail today and they are exactly what I was hoping for. I wanted to replace the 10 power bricks I have for my BFL Singles with a high efficiency atx power supply and get rid of the mess. These cables look great and they perform awesome! Thanks again Cablez and if anyone else is on the fence consider this a glowing recommendation.

I want to power 4 bAsic 54Gh/s. How would you built cables to power them. Let's suppose we know for sure each board can be powered with 100w.
Would you use one 8-pin PCIE connector per bAsic?
Can one 8-pin PCIE connector power more than one bAsic?
Here is my PSU mechanical drawing http://www.ocztechnology.com/manuals/psu/OCZ-Z850M.PDF
thanks

Considering we have only hints at what the power draw will be I will leave this here as 'the safe method' so far.
Looking at the specs of your PSU, you have twelve 12v lines coming out of the four modular 8pin PCIe connectors. Theoretically that means we could power 12 separate bASIC devices, but as your 850W PSU can only support 8 devices or less that # will have to do.
As for the cable itself I would suggest 16AWG as that would give us less voltage drop and be able to handle that kind of power for the most likely 6ft runs or more as they would probably be.
I would also make them direct to PSU cables so that we could remove any unnecessary 18AWG wire from between the power source and the bASIC and have less risk of burning. (at least until its tested thoroughly)
With that said I could build cables for you that contain up to 3 bASIC plugs each and connect directly to the PSU which should be the safe way at least until I can test other configurations out here.
Please PM me if you are still interested and thanks for the questions.

I had read from Inaba on the BFL forums that the new SC units sere to run off of 14V.
Has that changed? I haven't been there in a bit.
As for efficiency I think you are pretty close, there shouldn't be too much difference between the two voltages but only time will tell.

My electronics knowledge is probably a couple of decades out-of-date, but surely a traditional voltage regulator would be less power-efficient under over-voltage conditions (i.e. same current draw, but greater voltage drop across the regulator)?
That wouldn't apply to a DC-DC converter, of couse (and the chips obviously don't run on anything near 12V so presumably there's a DC-DC converter in there) but any reason why it'd be more power efficient at 13V or 14V than at 12V? I'd expect it to be about the same.
BTW, where does 14V come from - not seen mention of BFL products being 14V before.

ETA: I agree, though, that it's possible that their bricks have poor regulation, and although 13V nominal are really 12V under load.

Shitty bfl 13v = 11v under load. High end 12v psu = 12v dead stable

P.S. - There has been some confirmation that the new SC ASICs from BFL will in fact use the same plug as the current FPGA singles. This is great news for current owners of my cables. I will not advertise that fact yet until I see what the actual power consumption of the SC single will be though.
Though it's unclear what voltage the ASIC Singles will want. Inaba has said the ASIC singles will ship with a 13V power brick rather than 12V, but that they should also work with a 12V supply. Which seems a bit of an odd state of affairs.

My guess is that the voltage regulators on the SC units have the ability to work with varied input voltages.
I was surprised that BFL chose to go to 14V for power, I guess that is one way to show reduced wattage.

Ah the joys of my MMQ - it has a molex on it already
Yeah having the cheap power supplies that came with my BFL and Icarus' are a bit annoying.
--
Firstly, do your cables only take the molex (4-pin flat) inputs (single/4 or pair/8) or do they take the 4-pin/6-pin/8-pin rectangles like for the GPU's ... or do we choose?
Are the 6-pin/8-pin cables in PSU's usually powered to accept more Watts in a PSU? (I've no idea)
So ... if I wanted one for BFL singles, and one for a pair of Icarus, sent to Aus ... what would I be up for?
(and which of the 4-pin or 6-pin can I use)

Hi Kano,
My cables are fully customized to whatever specs you require. I generally stay away from the flat 4pin molex connectors as they only have a single 12v wire which is really only good for 1 mining device but if your setup demands it I can make it. I almost exclusively use the 6/8pin PCIe or 8pin EPS12v/CPU4+4 connectors which can power 3 or 4 mining devices per cable. They can be either an adapter type that could work with any ATX spec PSU or direct connect cables that would be specific to a modular PSU of your choosing.
In terms of durability of peripheral vs. PCIe or CPU cables, they are almost always 18AWG on production PSUs so the current limit is inherent in the wire itself. You do find on multi-rail PSUs that sometimes the peripheral rail has less amps than a GPU rail so that would be an downside to using it.
If you would like to PM me with specifics of your setup (i.e. - length, pitch, # of units powered) I would be happy to provide you with a quote. Thanks for your interest

Oh cool, I bought 6 cables for 12 BFLs but only got 4 so I have to sell 4 cables.
I'm glad the SCs will use the same cable so the trade in will be drop in. Unless they give me great power supplies unlike their last ones.

Hey bitpop! The only confirmation I have so far is that the BFL SC singles will use the 2.5/5.5mm plugs which is the same as on current gen BFL FPGA singles. This was stated by Nasser so I believe it.
Considering you were my first customer, don't worry about the cross post.
I hope someone picks them up from you. Just know that if you have SC singles coming those cables will work.

Cool, I hope the new single uses the same plug though.
If anyone is interested I'm selling cablez I bought here but never used.

So far the information out from the different ASIC manufacturers looks positive in that my cables will work with them. I am currently in no position to guarantee anything as of yet as I have no real hardware to test.
I am currently ready to take orders on cables and will do so to those that are comfortable with the information released so far.
When I know for sure I will most likely start a new thread solely for the ASIC cables.
Thanks for inquiring.

With the asic stats out, are you taking orders for those?
I believe he stated earlier that he can't be completely sure until he has an asic device to test his cables on.

Just want to say that Cablez is the man. I emailed him two weeks ago, told him I had 11 singles and wanted to see about dropping the bricks. A few emails and we struck a deal, a week goes by and he is ready to ship. I send him coins and then about three days later the cables showed up. Just hooked them up and ta da everything is working great. Less heat and less power, just a win win all the way around. Worth the coins and great job.
Thanks again,
Thanks again,
