Re: Which USB hub to use with Block Erupters or K1? A List.
Updated the OP. See if I overlooked any mods.
Oh and I saw this on MinePeon thread. Reposting:
Did you make or bought the power cables from PSU to the HUB's? I'm also using one of those 10 ports HUB (with 9 USB Gizmos), with a Velleman multivolt, that gives 7,5 Amperes @ 5 volts.
Originally I ordered some 2.1mm connectors but they haven't arrived, being impatient I cut the 5V lines out of the molex connectors of the atx psu (bottom of pic) and soldered the 5V wires straight to the hub.. and plugged the fans into the molex (which now only has 12V lines).
ATX PSU has 28A @ 5V 4X 20A @ 12V (Reserved for K16`s)
Your idea is great... i "invented" a cable, but I'm connecting the 10 ports HUB to the HD molex cable and 2 or 3 of the Gizmos were in error... perhaps not enaph current... Better to connect again to the Velleman 7,5 amperes PU.

Some said that problem with ATX power supply is that even if it says the current on +5V line is enough, You have to Load the PSU with all lines (like it is in PC) 12V3.3 +5-5 -12 etc etc, Only than the PSU ATX will work as it should be (dunno why). If done on a single 5V line there will be a hudge voltage drop, and below 4V on USB port Errupters won't work.
But I might be wrong, someone might have done something wrong while connecting.
Best choice is the industrial power supply cooled with a FAN, 2x30A with 100 BEE is working perfeclty as planed.
Now I'm planning toupgrades BEEs to 16Mhz crystal (450 Mhz), more power drained more heat, (new heat sinks should be here today You will love them), Disadvantage is that you probably can't run it on normal HUB due to more than 500mA of current (once its done I will make all measurments necessary and post them).
Morning all.
Would this dc 12v power adapter work?

If its not for USB 3.0 HUB's which have 12VDC power input.... it will damage 5V Hubs.
