I don't see any reason to buy a PSU until they've announced that they are shipping.  You never know if they'll come back with specific PSU recommendations that are tested and known to work instead of just guessing.

Fair enough if you have a store close to your location, or are serviced by an efficient postal network, but globally this isn't the case. They mentioned the need to inform their more 'remote' customers, besides people had been bugging for sometime about having fair warning...

Good point. I am in the US and I'm used to getting shipments in 2-3 days.  I guess I get spoiled by Amazon Prime.

You should get a 1000 watt to be safe.  The one from new egg above seems to be the consensus on other threads, IMHO.  Cheaper too.

sorry but I can't get it maybe I'm slow Smiley

knc seems to state that theirs "at wall" wat per GHs is 1.6 W

then as max W requirment we should have 1.6 * 400 = 640W

am i missing something obvious?

I bought this one
http://www.newegg.com/Product/Product.aspx?Item=N82E16817171078

Do we need anything else?

Possibly a paperclip...

Looks like a good choice to me.  Just bought one myself.

At the moment I'm thinking I might go industrial, something like:

Mean Well RSP-1000-12


and something similar but lightweight for the 5v.  Depending on prices, I might go for current-sharing with multiple smaller 12v supplies and add in some redundancy - not sure yet.

Just ordered a lot of 20 of


via aliexpress for USD 15 shipping included.  Easier to chop off and chuck the 8pins than making the 6pin cables by hand.

What sort of costs are you guys looking at for PC PSUs?  (I'll post what prices this approach is costing when I get quotes next week)

Looks like KNCMiner just came out with information regarding PSU. 
https://www.kncminer.com/news/news-31

Quote
So today we can reveal the following recommendations;
We recommend an 850 Watt PSU with a minimum of 4x PCI-E adaptors for our Jupiter model.
We recommend a 600 Watt PSU with a minimum of 2x PCI-E adaptors for our Saturn model.
We recommend a 400 Watt PSU with a minimum of a PCI-E adaptor for our Mercury model.
This recommended power wattage figure is calculated upon our max. power consumption of total device including all of its components.
We aim to ensure you use a power supply unit capable of outputting in excess of the current recommended wattage to prevent any problems caused due to insufficient power.
Note: Powers supplies must contain a sufficient number of PCI-E adaptors for each respective unit.

With the recommendations, which PSU is best?

Any news on power supply yet?  Specific products?
No, people are speculating, but nothing official from KNC.  The consensus is that there will be plenty of PSU's available.  There's no shortage there.

This is realllly confusing. Why are you answering your own question?!!
LOL!!  I got an email notification of a new post and just went to the thread and answered the question. LMAO!!!!!!!!!!!!  I don't know why I got a notification of a new post.  Maybe someone posted and then deleted it.  That is pretty funny!!!  I wasn't paying any attention.

Naturally BFL Josh would say that. But Knc is not an American company, therefore less regulation and more/easier innovation.

Umm...if you think there is less regulation in the EU than the States, you are gravely misinformed!
Switzerland is technically not part of the EU.  And innovation in Swiss. us top notch.  Don't want to hijack this thread.  Maybe a new thread?

Last I checked Sweden was though, at least it was when I visited KnC personally two weeks ago...

They are producing 28nm ASIC hardware due to be delivered in Sept/Oct.

The originally advertised 250GH/s for 7-8k USD and ended up promising 350GH/s for under 7k.  We are currently awaiting final GH/s estimates (they are hinting that it will end up higher than 350GH/s for the Jupiter unit) and their Power consumption looks to be below initial expectations as well.


they're not hinting GH/s estimate, in the last news they actually said "It is with great pleasure that we can finally announce our Jupiter is now a 400 GH/s device ". You have a point about on the power consumption side since they said: "We have previously specified the power consumption of the Jupiter device at a 1000 watts. We have now received indication from our chip manufacturer that this may be lower."

Hi Guys

Sorry for butting in in your discussion but don't buy any power supplies yet.

We will have a large Technical announcement coming next week. Where we will give even more accurate Power figures and GH/s.

It will be a significant announcement which I hope will make all of our customers happy. and no before you ask I wont reveal any details before that newsletter goes out Smiley

again please don't buy a 1200W power supply you simply will not need one that powerful or expensive.

Waiting to hear, when does the newsletter go out?
Wait, when did KNC become legit? I always thought they were another start-up-scam-of-the-week.
If you spend all your time in BFL threads, you miss things.  Shocked
Well I read a lot of BFL and Avalon chip threads, and try to stay pretty informed. Stay out of the ASICMiner threads, and the other little ones. Sorry I don't read every single thread on this forum, but that would be a full time job itself.

Thinking back, I think I heard they were using FPGAs, and thought their performance numbers were a little "optimistic", so I wrote them off, and haven't looked into them since.

In the mean time, where do they stand? They're using FPGAs, but somehow have the best prices, and power efficiencies, and will be delivering soon?

I wish more people would stay away from the ASICMiner threads.  Good man.  That operation and strategy is like digital Chinese SARS attacking Bitcoin.

I've talked to KNC a lot.  Sam makes a lot of sense when he contrasts their business model with BFL.  He's a nice guy.  I believe them.  I didn't go all in, but I will if they deliver.

So, if one were to get 1 Saturn & 1 Jupiter, can they use one power supply for both or need two separate?
Depends on final power consumption and what wattage your power supply is...
Ya 1500W is a lot for one PSU, tho it can be done.

Hopefully he will be ok with a 1200w as they are easy enough to acquire at a reasonable price.

Finger's crossed anyway...

No.

They only created the Mars FPGA unit to show that they could rapidly produce a device.  They then had (multiple) open house days to show they were legit.

They are producing 28nm ASIC hardware due to be delivered in Sept/Oct.

The originally advertised 250GH/s for 7-8k USD and ended up promising 350GH/s for under 7k.  We are currently awaiting final GH/s estimates (they are hinting that it will end up higher than 350GH/s for the Jupiter unit) and their Power consumption looks to be below initial expectations as well.

They by all outward appearances appear to be the best bet in the Asic for Pre-Order market at the moment.
Ya I realized I was thinking of their Mars, but their two new ones are ASICs, which makes sense. Thanks for the quick recap!

 Thanks for the update. I was skeptical of KNC myself and it's good to see there is community support for them.

 I'll be watching with great interest in Sept/Oct. It would be amazing if they pull this 28nm product off in that timeframe. Not an easy task to accomplish at all. Wishing them Godspeed with this project.

Tease, sounds like more GH and/or less W, either of which is good Smiley

Wasn't buying anything until nearer the time, was just pointing out with the cost of the unit and low power usage means no point compromising on PSU quality

Corsair all the way, been faultless on all my rigs.

Saving a few dollars on a cheaper makes, or getting a lower powered one that 'should' do is silly, or a lower powered one to get it into the 'optimal zone' is going to save just a fraction short of f*** all.

Buy a big one, then relax Smiley

to my understanding, the jupiter devices will not come with a PSU? what brands and models are you guys looking into and why? KNC says jupiter will consume less than 1000W of power, so - is there really a difference between using a 1000W PSU and a 1200W PSU? anything below 1000W PSU for jupiter is going to damage the device?

  • Digital Signal Processor (DSP)
  • Active Power Factor Correction (PFC)
  • Universal AC input from 90~264V
  • Over-voltage, under-voltage, over-current, and short circuit protection
  • Self-test switch to determine PSU functionality even before installation
  • Seven year warranty

With that PSU, your sure you won't have any problems.

I'm not that familiar with the difference between the Gold and Silver ratings.  Assuming close to max load, how much would you predict saving (%) using the Gold over silver?

Assuming the Jupiter comes in under power estimates, and the difference isn't that great, it might make sense going with your suggestion.

I would consider waiting as 1000W is a margin, and KNC may have power usage as low as 700-800 watts on the finished product.  No point in buying something before it is necessary anyways...
