What PSU model would you recommend?

It would depend how many H-boards are in use. A starter kit would work fine with a 350W supply, even a 200W supply likely. A full 400GHash rig would need at least 500W (assuming that bitfury is operating near the 1w/GHash design), but a 750W supply would be best

That's not true in regards to the 400 Gh rig power requirements. Please read post #973 https://bitcointalk.org/index.php?topic=251966.960

Dave,

How do you guys power the full kit?

The M-board draws 40W, right?  Is that with H-Card plugged in or just M-board?

Does each H-board draw power from M-board?  On your pics I don't see anywhere on the H-board where the power can be injected.

Some big wires have to come from PSU to M-board to drive full kit 640W+ (53A+ @ 12V) so, we'd need like 6 gauge coming from a three PCI-e
8-pin combiner, or maybe a very short 8 gauge might do the trick?

I'm just trying to prepare my PSU for your kits.

Thanks,
af_newbie

Are you saying the full kit will only draw 360W from the PSU?

each cards draws 40 Watt, 16 cards add up to 640 Watt, that was correct. Also didnt punin mention that they "missed" their goal of 40Watt by 25%? so 0.75*640 = ~480Watt  Cool

Thanks tom99.

So two PCI-e 8pin cables soldered together should be enough, with 10 gauge wire from the combiner to the board (ver 1).



I'm trying to move both efforts forward - producing the new v2.2 M-board that has the PCI-type connectors, as well as producing cable adapters to allow the V1 M-board to connect to your PSU.  You shouldn't have to make anything on your own.

The adapter cable will use two of your PCI-e cables from your PSU.  Each PCI-e has (3) 12V and (3)GND wires crimped into a ring terminal connector: http://imgur.com/a/CoAO4 (quick prototype made by Cablez)

Morblias, read dave's response above. Looks like he wont be able to turn around the 2.2 boards for august.

Oh, darn! I took forever to post that last one since I got distracted by work and didn't read the latest responses haha.

On the EU thread punin posted pics of v2.2 master board that is powered with 2 PCI-E connectors. I am assuming these are the same ones Dave will be using.

I'm out of time on the v2.2 M-boards for August product delivery.  Niko might be able to pull it off for his orders, but I don't think I can - I won't order these boards on a quick-turn if they aren't tested yet.

Meantime for powering your rigs from an ATX PSU, Cablez was nice enough to whip up this proto on a Sunday afternoon.  http://imgur.com/a/CoAO4

I will get them made locally so Yvonne can pick them up.  Alternatively, we may ship the raw materials in a kitted form (crimp pins require a special tool, so we would do that part), depends on time...



i know promises are important. i assume some people would be ok with it being a day late with everything proper
how long would the delay be for those who wish to get v2.2?

Niko is very close to testing his v2.2 boards, so its still possible.  The thing about quick-turn is making sure all components are on-hand before attempting to estimate that production timeline.  I don't think even a day of delay is acceptable for the different board though - its not much of a difference.

I can see trading them out for you later when I have them in stock...

Niko is working with a different fab to try to get additional pipeline going.  He already has PCB underway from last week.  Not sure when they will begin assembly.

I'm expecting status from China late tonight - I hope we will have confirmed operating H-boards!  At that point, we will go full speed ahead.  PCB is not waiting for this - we took another big $$$ gamble that they will have PCB correct this time, so the assembly is the only thing waiting for this confirmation.

Given the proximity to shipping time, I still don't see the shipping options in "My Account."  I thought there were going to be a few available to choose from.

I hope I get my August kit before August 29th.. I'll be out of town for a couple days then and I don't want to miss out on hashing right away. I just hope everything will be OK. I won't be overly worried if Dave is a few days into Sept..
