I can confirm that the $45 5V 60A power supply works with this hub.
It's late here, so pics tomorrow!
OK, as promised! First the money shot:It's late here, so pics tomorrow!
The rest of this post are the steps I took to make this work. If you're going to try this you should at least know how to do basic soldering, crimping and heat shrinking of cables.
One thing to note is that it looks like the power LED on the hub is powered from a 3.3V line, so it won't work if you go this route.
1. Here is the ATX pinout. We'll be connecting all of the black and red positions to the power supply.
2. I got this Meanwell 5V 350W supply:
The price varies all over the place, and there are many similar supplies on ebay available out of China. They all look about the same, but getting one from a reputable company for only $45 was pretty nice.
3. I used 18 gauge wire. 16 would also be good. Don't go any lower than 18!
4. Get yourself a 24 pin ATX connector, mine came with pins which was nice:
5. Attach pins to eight black wires. Here you can see the crimp:
6. Because I don't trust crimping, I always solder these type of connections too:
You can see the copper wire is now covered in solder and very strongly attached to the pin ;-)
7. Add some heat shrink. Don't put the heat shrink too far down the pin or the pin won't go in the socket correctly.
8. Insert the wires into the connector following the pinout above. The pinout above is looking at the *face* of the connector, so you'll have to take that into account. My connector had pin numbers stamped on the back so it was easy to get right.
9. Repeat with red wires:
10. Now on to the AC power. My supply had a "L" for line, "N" for neutral and GND for ground for the AC connection. Here in the US the line wire is black, the white is neutral and the green is ground. Please get this right! Also, I'm using ring lug connectors. Again, I wan't everything to be very well connected. Ring connectors can't pull out like spades or just bare wire, so I like them best.
11. First I hooked up the AC line to the proper terminals and then I connected a DMM to the output.
12. Looks good! I adjusted my supply to 5.2 volts. USB spec is 4.75-5.25 and the slightly higher voltage will result in the miners using less current (amps), which is good.
13. Now I added ring lugs to the ATX cable. There are only three output terminals for + and - on the supply so you need to balance the wires as best as possible. With 6 red and 8 black this works out to 2,2,1 and 3,3,2 for red and black respectively. Solder these connections too!
14. All hooked up!
