Using my Windows desktop as the controller. Power draw, good question - I don't have the tools to measure that. At a guess I'd say 0.7A@5V * 16 = 56W.
Nice if you want some Twin Chip Bitfury Miners (4-5 gh/s) I have them for $35 usd each

All overclocked to 54 oscillator bits, there don't seem to be any power-related error messages; it seems rock solid
Very happy, can't wait to get the rest!

Guys - dragging your dirty underwear here is probably not the best way to resolve your issues ... that is unless you're trying to drawn each other...
What happened in the past happened in the past. Leave it in the past.
If there are lessons to be learned - learn them. Then find a way to bury the axe. And move ahead. Don't stay stuck in the past.
If you really insist on proving to each other who was more right and who was more wrong - take it to a court. Those forums are not courts.
Each of you has come up with a different product. The market is big enough for both of you.
Just my 2c.
edit: Just cut the crap and get back to business.

Just to let everyone know here that i am no longer working with RF. There is no connection between us.
Here is what he has been saying about our "business relationship"
OK…..
So here we are, after my last post clarifying the situation:
Show and tell
1. Further mis-representations: If someone came to you and asked you to setup a system using PP split-payment API, where they received 50% of the money for physical goods they did not ship… how long would it take 'you' to setup such a potentially fraudulent system, or would you just keep dragging it out with excuses?
2. Would you setup a website on a domain name and server controlled by a guy you only just met, who openly boasted about HOW he fucked his 'book selling ' partner over and wanted to setup a 'limited liability company in Hong Kong' with you…. ?
Personal character
2. Harassing phone calls to my mobile phone, sometimes as many as 5 a minute, because the curtain has been pulled back in OZ.
3. A definition of what "rework" means http://scn.sap.com/people/rupesh.brahmankar3/blog/2013/07/06/rework-in-manufacturing
for those who don't understand the difference between 'rework" and Having to open, inspect, remove,repackage and test cable sets then having to completely repack goods.
4. Offensive pm's + Further falsifications (it is the first I heard….), then WHY did you state it was TRUE in your PM). (see below)
6. Yep the 'blue fury', go read up interview techniques and evaluating potential business partners, with this simple but effective test I get a complete breakdown of a persons 'claimed' area of expertise.(I could just have used google!!)
Did it NEVER enter your thought processes of how at 21 I was the technical director of an electronics company turning over $20million a year If I was such a 'fuckwit" with electronics?
Correctable traits
7. A complete inability to articulate conversations as an adult, with valid point of contention.
8. A complete inability to get my name right..
9. The use of 'shill' accounts to promote himself in his own threads.
AGAIN I will state this:
I think with each passing day, this conversation justifies my decision.
RF
In attempt to discredit me because he doesn't like the fact that I undercut him in prices...how pathetic... he has twisted all the facts he knows about me. As if half truths could prove things that can't be found on the internet in the first place! Like for example trying to suggest i screwed over my other partner in a different business venture, when in fact we are still working together (I only told Steve that my business partner was a little lazy due to the fact that his wife just had kids and I was unhappy to have such a heavy work load because of it).
Anyway read what he said and then see the truth for yourself. Its lucky that i kept all these messages. They certainly paint a different picture to the one that Razorfish is trying to past off as the truth.
The truth:
The real reason we split up from Steve (i.e. Razorfish)

fuck off out of my thread. It is for people interested in buying the hub not for you to whine like a fag, Mr Steve Green you fucking cunt.
You never reworked that shit or at least you never told me. You told me that they were in fact in good condition. All you ever got were new cables.

Hi Philip,
I'm glad you are happy with your purchase.
The 19 port hub is one of the few products I am happy to leave switched on 24 hours a day/ months on end, 90% humidity. So far it is also the only hub that has not damaged my USB controller in my mac , nor overloaded the samsung SBC's I use.
But yes, your quick analysis on 'ATX' power supplies is fairly close to the mark, anyone with a screwdriver, half a brain and google can quickly look up the specification of the internal switching components of the ATX and can soon realize most of the ratings on the ATX cases are complete bullshit, you only then have to cut a wire and count the wire strands.
I have 2* 50A@5v PSU I designed for FPGA mining back in the early days and even with single strand 2.5mm2 copper( 300v mains) the wires get hot…….
Legally many ATX are just skirting the regulations for consumer labeling requirements on honesty (in a pinch even a car engine can be started from a couple of 4R25 batteries, so technically you could state that they can supply 400A, the fact that they may melt and are totally destroyed is irrelevant)
Perhaps one of the worst things I have ever seen in a Chinese made ATX, was a 110/220 conversion done via a diode, rather than utilize a tapped transformer , they decided to save the cost of the copper windings by using the diode to 'clip' the mains cycle by 50% producing a shitload of heat and more filth(EMI) than a german porn movie.
I've been less active on the forums recently due to new projects and hope to post some new designs I have been working on that will further enhance the lifetime of the 19 port hub with the new multi chip bitfury miners.
But basically unless I have 100% personal faith in a product I will not sell it.

Wow you have a bunch of irons in the fire. I will let you know if it does not power it. I hope to have a review unit in a couple weeks for my article.
Yep,
It once again highlights why buying Nand flash sticks in China is a high risk proposition, I just wanted them for the viri they come pre-installed with.
Also if during your research you find the hub won't power the PI due to the power requirements PM me directly I already have a solution.
I've been working on a Quad core mining controller which I finished the new kernel build for a couple of days ago but I also ran into issues with peak current consumption.

That is great news and bad news all at once.
Great that the hub is that solid. Mine works great. I have added Ants and DualMiners to it for testing and my 20 gh/s Jalapeno. No issues what so ever. A Pi will be running off it eventually as well.
The bad news is you have that nasty burnt smell in your house.

Hi,
Glad you received it in good condition and I see it is performing well.
Yesterday I was working on a new project using this hub and a some flash drives i purchased in China over the weekend
I'm thinking WTF is that burning smell, but put it down to the locals roasting some cats on the BBQ's they like to have.
Nearly an hour later I identified it was from near the hub, tracked it down to one of the USB flash drives.
Opened up my hub expecting to see something burned as well but there was zero damage, the poly-fuse had cut in and protected the other devices, power supply and PCB (that's the hub pcb)
This is the second time this month that the hub has saved me a shit load of heartache, the first was on a load of USB->Ethernet adaptors, where they had wired the power rails backwards!!!!
Normally with such failures on an "ebay hub" you would see the PSU dump the whole current onto the faulty device until the short is burned out!!
Which results in all sorts of damage and possibly a house fire.
When you consider how many USB 2.0 hubs you purchased over the years , plus considering this hub has a life expectancy of years it really is good value for money.
Plus with this hub you can power a PI from it and mine all from one power supply, instead of needing a separate PSU for the PI
As Guy Kawasaki pointed out "you can compete on price or quality" ;-)

Just received the USB hub I ordered from razorfishsl last week.
Ordering was very quick and easy, and razorfishsl provided updates at every step.
Shipment was quicker than I expected, and the hub arrived in perfect condition.
I've populated it with 8x Antminer U2 and 1x BFL Jalapeno to test it.
Seems to be working flawlessly after tweaking some of the bfgminer options. Best of all, no hardware errors whatsoever on any of the Antminers after 30 minutes:
Highly recommended. The hub may seem a little expensive, but it's well worth the price.
Many thanks!
