Given the costs involved, pushing any power supply over 100% load (or even 89-90%) is really unnecessary and asking for trouble. It's a little different than a GPU rig where you have 4 5970s worth $1200 on a 1200W PSU, another $300 for a nice PSU is a pretty minimal charge compare to the cost of eight 54GH/s bASICs.

This. 

EVERYONE: If you're running more than a handful of the ASICS, purchase GOOD power supplies and calculate UNDER 80% of the stated wattage.

PSUs and molex connectors are great, i'm sure, but I for one do not have a pc to use with my bASIC. I will be using a RPi to host it, so molex  and PSUs are out of the question.

I suppose I will wait for you to specify exactly what kind of dc adapter we will need.

Me too I'm not interested in molex stuff.
Tom could you please just specify exactly what kind of dc adapter we will need and make it easy.

Thanks

As far as I know, you can force a PSU to power on by tying 2 pins together on the ATX connector:

http://pinouts.ru/Power/atx_v2_pinout.shtml

Just short PSON to ground permanently.

Or you can buy a ready-made gadget for this purpose:

I also now provide switches for your ATX power supplies if it is not the host system: Can be for modular and non-modular types. Pricing is 1.0BTC each

I'd buy one directly from Tom also. He should know which one is best.

Tom owns BFL Singles, and seems smart.

I'll bet it is the same plug BFL is using.

Hey, where's the FAQ for this thread?

I might have a go at setting one up tonight - we can do it GitHub style so other people can contribute.

Also, just a note to mention that if you're like me and only powering 1-2 bASICs you won't need the 1000 W PSU. I've bought this personally; enough room to move, but not overly expensive. (Also, I wouldn't mind if someone chimes in to double check this would be okay - second opinions are always nice)

Update: I've made the repo here: https://github.com/XertroV/bASIC-FAQ

If anyone has a spare moment please have a look over this and let me know if anything is incorrect. There isn't much there at the moment, but it should fill up over the next few hours.

Cheers

Thanks but now I'm more confused. I have to power only one bASIC  54 Ghash/s  and I don't understand how.

"The barrel connector is thought to be a centre +'ve 2.1 mmID 5.5 mmOD type. (ID = inside diameter, OD = outside diameter)."

So what? can't find nothing like that with Google.
Wouldn't be more easy to tell exactly which model or type  or at list detailed specs or even a pic.
A link to Amazon or eBay or whatever would also be highly appreciated.
My feeling is that at the moment no one knows which barrel connector is the right one to power just one bASIC. Even Tom.

"A bASIC will not ship with any power supply. However, you can buy a PSU that is compatible from Tom's store"     

Why only PSU and not a barrel connector too. I will order one  immediately.

Really useful information, thank you. I'll comb through this thread and try to find relevant links for the Shipping Dates for you. (the bit I'm most concerned about)

There are so many pages of non-relevant text, it is hard to get the right information and asking for it comes with a troll label.

I'm also still confused about which parts are completed and which are being worked on. Anyway, I'll read back a while and see what I can come up with this morning.

Do not connect 10000$ of equipment to a single power supply, please.
Shit happens.

I've added a paragraph about that now.

If anyone has any questions they'd like answered please quote me and I'll be sure to look out for them and try and add them to the FAQ as best I can.

for board power we included the option of using either 4 pin molex or your common 12v dc barrel jack connector like what they use on the bitforce single.

As we do not provide power supplies for these units we wanted to make sure everyone would be able to power their units in the way that they wished.

My personal opinion would be to

buy something like this:

https://www.bitcoinasic.net/index.php?route=product/product&product_id=54

which is a highly efficient and top notch PSU - as far as I know the only PSU certified to platinum efficiency status is Seasonic.

I personally use these on my fpga rigs - one of these 1000 watt babies will easily power 8-10 54Gh/s bASICS


Tom just let this out of the bag....great news.

Seems that it will be under 100 watts.

Would anyone care to recommend a PSU suitable for powering just one bASIC? Should I just look for the gold/silver efficiency stickers on a 400-600w model?

Trust me, these default swaps will limit the risks

Exactly. If you expect one power supply to handle $9,000 dollars worth of equipment it better be top notch.
