Can one of you show how it's hooks up?
I second that!
I put up a blog a while back as I was getting to many messages asking about using PSU to run hubs off of. http://aurel57.blog.com/2013/09/29/asic-miners-usb-powered-hubs/ I use 20A 5v PSU's to power 4 hubs running 28 USB miners. (A person should be able to power the 49 port hub with a 40A PSU without over stressing the PSU.)  My first 20A PSU has been running a couple of months without problems. Since I have added 2 more PSU's and have 10 hubs running 70 miners now running. The wiring is pretty straight forward. For the 20A PSU I bought a cheap power strip that had 14 gauge wire and cut the cord off. This is wired  to the line +/- of the PSU. If using 110v wall outlet make sure your PSU switch is on the 110v and not the 220v as most have duel power. Now on my 20A they have 2 output ++/-- this is where you will power your hubs from. Since I wanted to run 30 USB miners from one 20A PSU I used 4 hubs so I could wired 2 hubs to each side of the power to balance the load. On a 40A PSU there is 3 +++/--- outputs. Without a 49port hub its hard for me to tell just how to wire one of these 40A PSU so the load would be balanced on all 3 outputs. I hope this helps some.  Here is a close up of the 20A wired to 4 hubs (I added a cheap led volt meter as to keep a eye on voltage)

Just updated prices on blades.

Also, there are no more USBs available from the manufacturer.  Whatever remains on hand at resellers is it folks.  Once they're gone, they won't be restocked or made again.

I still have plenty on hand with good color selection and offcourse 50 units include the 49 port USB hub.

I second that!

To add to Aurel's post (most of this is the same as on his blog):

Supplies:

1) Multimeter ($30 at Radio Shack, a lot cheaper from ebay)
2) Wiring to connect the PSU to your hubs (can also just snip off the plug from one of the cheap 1A/2A power supplies and strip the 2 wires): http://www.mcmelectronics.com/product/27-5990
3) Extra Power strip
4) Philips Screwdriver
5) More common sense than me (I initially bought a 12v PSU and blew up 2 hubs...Yeah - a loud pop and smoke haha)

After getting a power strip and literally just snipping off the plug, you should have 3 wires, strip the insulation off each of them so you have inch or so of exposed/bare (copper?) wiring,  

You need enough stripped so you can fit all 3 wires on their respective screws but not too much so when you close the little plastic safety latch there is still enough exposed wire to still end up hitting the wire and shocking yourself.

Green wire connects to  GROUND (the weird symbol)
Black (may also be red) wire connects to L(ine)
White wire connects to N(eutral)

Keep it unplugged.

Get the plugs you ordered -
White wire is + POSITIVE
Black wire is - NEGATIVE

This is how I lined mine up:


+     +     +     -    -    -   So first hub i connected got the 1st positive with the 1st negative, second hub got the 2nd positive with the 2nd negative, etc...
|                   |
---------------

I had more than 3 hubs so i doubled up with +/- terminals.  I think I have 5 connected total.  

Make sure voltage switch is set to 110 if you're in the US. Plug in the PSU, it should power on.  Make sure you have a fan on it if it didn't come with one built in. Take the multimeter, touch the black probe to the first negative screw/terminal then touch the red probe to the first positive screw/terminal.   Adjust voltage as needed to make sure it reads 5 and 5.5v.  When you're done, plug in your hubs! And close the plastic safety hatch thing.

This is how I got setup running (40A) and it's been going strong for over a month.  If I have anything wrong here please let me know so I can change it.  Here is a close-up of my PSU:

ONE place to buy idiot proof dc plugs is good old mcmelectronics.com  unlike the crap pus's early in this thread they have a great dc power cord.  it has a blue led and a red led.  if wired wrong for hubs the led is red .  red is dead you will burn the hub up.   if the led is blue it is wired correctly.  give me a few minutes. i will post some nice 7 port hubs


http://www.mcmelectronics.com/product/82-12675   link for the wire same code afc909 for discount.

now that sticks are going going gone  I wonder if AM will  sell a better stick. It would be nice if they cut a deal with bitfury and made the 2.5gh sticks just as fast as they made these sticks..

okay my photos of 4x    7 port hubs hooked up.  


using the magic dc power wires blue led is cool red is dead.



a low cost 3 prong switch from lowes. 




the cut 3 prong power cord from an old power strip  one in the switch from lowes and to the psu

a close up of the psu   note the red electrical tape over the 3 ac power wires is for safety as it is live power .





last the psu is good for  26amp 130 watts at 5 volts    my 4 hubs are 28 sticks and pull 100 watts at the wall.  so this is a great setup for 28 sticks.





this would be a perfect  setup for the bitfury sticks

Just updated prices on blades.

Also, there are no more USBs available from the manufacturer.  Whatever remains on hand at resellers is it folks.  Once they're gone, they won't be restocked or made again.

I still have plenty on hand with good color selection and offcourse 50 units include the 49 port USB hub.

Are the blades still in production? Or are they stopping production on all BE100 based miners.  Maybe gearing up for V2? Wink

if they made a new stick they need  a different chip.    even 1gh-1.5gh stick with power at 2.5 to 3 watts would work.

V2 = smaller process node, same design.  Maybe then, higher clocks and/or x2 chips per stick would achieve 1-1.5Gh.

I have not seen the PSU but I suspect you could just connect all of the red wires to V+, all of the black wires to V-.  The rest of the wires could be removed from the 24 pin connector or ignored.  I think they all float on the hub side except for the green wire that turns on the ATX power supply. 
This wire is even mute with a dedicated 5V PSU.  I think I would rather wire in a switch on the 5V PSU.

Whithout having one in front of me:  find the pinout assignment for all the +5v connectors on the psu (the wiki page should show you which ones and they're usually the same color) connect those to that psu's + side, then connect all the black ones to the negative side.

I'LL provide a pic once mine gets in and go into more detail, but this should get a few people going in the right direction.

You need to balance the load between the three outputs.

You can use something like that, for both the blades and USB miners
