This is the Dell PSU and breakout board that I bought. It's a Dell 750W PSU that powers Dell PowerEdge 2950 see link below.

I see others posting very good Hash rate using these PSU so I ordered 2 of them but my results are actually showing only 12V and slightly lower hash rate then my EVGA. The breakout board is pretty cool as it does have FAN control so I was able to reduce the noise level greatly due to FAN not needing to be on 100% power when it's freezing in garage now.

they should. whats the model.

Thanks Oregonmine.com . I'm using the 2 x Dell 750W PSU on 120V outlet. It's showing as using 12V and the results are pretty much the same as when using the EVGA. I'm now curious as to whether people were getting 3.7-3.9TH by using 240V outlets for higher efficiency. The Dell 750Watts on the 120V outlet is showing only 12V so it's not increasing the voltage at all on it's own. I'll wait until others who have tried this chimed in.
You should be able to do it on 120 to. I have not used the Dell 750's but a lot of the ones that do have something to adjust it and voltage goes up or down depending on adjustment.
Anyone use the 750's and know if they have a voltage adjustment?

Those of you who connected 2 PSU to the Avalon 6. How is the HASHOARD layout? Is it top to bottom or is it left to right? Just received both of my Dell 750W PSU and want to it another try. When i open it, the board appears to be left to right but I'm not 100 certain without opening it all the way and voiding my warranty.
Left/Right, The side with the Avalon Black Sticker is one side. The connectors on a board face the same direction. December 17, 2015, 04:49:31 PM

the r/c guys have lots of good info on many different power supplies as well. some great write-ups with good pictures and explanations.
heres just one example: http://www.rchelination.com/setting-hp-dps-1200fb-power-supply/

Here is something for the electronically enabled:
Here is an obscure thread regarding the mod of a power supply to adjust the bus voltages. Discussed in this thread is the fact that some power supplies have onboard pots to tweak the 3.3, 5 and 12 DC outputs
http://hardforum.com/showthread.php?t=765175
Now opening up an ATX power supply is a potentially hazardous endeavor and messing about inside could kill you, so the responsibility is your own.
The big capacitors must be discharged WITH THE UNIT OFF AND UNPLUGGED from everything.
If there are multiple pots, you have to figure out which one controls the +12V output. You will also have to figure out which one increases or decreases the 12V output.
This will upend power supply selection somewhat if there are particular brands that have a board level pot to adjust the +12V output.
The thread has useful safety information which should be consulted.

Why risk the warranty and try that? Our PI controller can already control multiple units via the Daisy chain.
And it is one of the nicest warranty's out there. I thought don't know if we mentioned it in a while. So a lot might have missed it. BlockC - http://www.blockc.co/pages/warranty-agreement
A. If still within the Warranty Period, Avalon Manufacturer’s Warranty will transfer to the buyer, upon equipment resale provided that the buyer contacts Avalon or BlockC.co to register as the new equipment owner.
B. In order to receive Manufacturer’s Warranty coverage, you must notify Reseller with your contact information, the equipment you are operating, and a description of your operating environment.
So 90 day warranty can be transferred to new owner just need to notify them. Which is great to that if sold another owner can have that warranty.

I don't think it's worth the risk either on warranty. If someone want's to try they are welcome to share results. I can't think of good reason unless a controller went bad and you had 2 units. But even if this happened I think most will ask for a controller from BlockC or Ehash.
But you would need longer cables or something to really make it work full time. So daisy chain or multiple USB is what I would stick to. As no doubt kills warranty opening it. If you sent in a email and ask they might give you the anwser if anyone is really curious.

I see from the picture in the new dogie guide that the controller has connectors for 4 Hash Boards.
It could be that you can plug up two miners to one controller?

It is quite interesting. From his pictures we can see it using 2 of the 4. I don't think anyone has tried out doing it but looks like a possibility.
I doubt we will know unless someone tries it. Most likely will be a Ehash customer that tries it if someone does. It does not have stickers showing if opened. BlockC has stickers over screws.
I have 2 units but I will wait before I try that.

I don't have one of these...don't plan on getting one (13c kwh electric) but was wondering..what is the 'electric price point' in folk's opinon you would need 'minimum' to make more then ROI (hopefully) on one of these units...with the added assumption that you could get (1) unit say with shipping included at $1650 usd or so (which I think would be a very good price for 1 unit)
Just wondering how far in the dark winter cold I am away from this ...electric price wise
Myself I'm thinking at least less then 5c kwh usd.....and I would not be sweating this too much on the above....what ya all think higher/lower etc?

This is really a whole different topic. ROI is hard to predict long term. With difficulty changing and btc value changing.... we really can't say at X price you will ROI. If anyone does.... chances are they are lying.
What we can say is cheaper the electricity the better chance you stand at ROI. With 13 cents your best bet is if you used it to heat a room for winter and not using heat as much.
It is something you kinda have to love to do. I have always enjoyed mining and tinkering with the machines. That is why I do it. And I do watch to get ROI. But it is hard to predict so far away.

Anyone find a vendor selling the Avalon under $1400 yet? I'm looking to add 1 more, mine is still running strong and super quiet. Looking forward to doing 3.9-4TH with the IBM PSU like Phillip is doing so these will be my go to box if I can get them cheaper.
P.S Zoomhash customer service was very good and fixed the issue with the missing Dongle very fast. I got it this morning.

Coincidentally 4 of my 6 miners just got the 'blank mining data' issue. Tried hard reboots to no avail. Tried to power them up first and then fire up the pi after, still no luck. Switched form antpool to F2pool and they all came back up 100%. Weird they wont show the connected devices, wattage, etc until they connect to a pool. Thinking the pool is related in some way as I have only been mining on Antpool when this has happened. IDK... Best of luck on experiment tonight rootdude.
makes sense that antpool might not like an avalon 6 mining on it. I suppose they can tell what is mining on their pool.
I have used the avalon 6's on
solo ckpook org
mmpool org
f2pool org
I have used multiple did not do solo. I did test antpool and had no issues. I can't imagine bitmain doing anything to stop people from picking them to mine does not make sense.
But I have put at least a day or two on it and had no issues. On a side note if you want to see interesting pool owner talk you don't see much check out SPV mining topic in pool thread... it's very interesting and worth a read.
