Power Supply Issues using ASIC BLOCK ERPUTERS on 10 USB HUB

[8-bit]

Every week I seem to have one power supply fail on my 10 slot USB ORICO hub. (never had one of my anker 9 slot hubs fail)

I'm using 10 asic block erupters v3 and plugged directly into a power strip that is plug into the wall.

The power supply units came with the hubs and are 4a 12v, any help is well appreciated.

thank-you

Why can't you run the hubs off an ATX PSU like everyone else?

Im not using the 49-Port ASICMINER USB Hub

I have a single 10 slot usb hub that came with the appropriate power supply unit. These hubs require a 5.5mm 2.1mm jack, so won't getting a atx power supply be useless?

Well you have 48 Watt Power Supplies dying repeatedly under 25 Watts of load.  Either you are getting one crappy power supply after the other or your exceeding the limits of the "appropriate" power supply.

Some people are using ATX Power Supplies to supply their USB Hubs so that they don't have all of those wall warts.

So find out which one is your problem and resolve it.  If something is exceeding the limits of your power supplies then using an ATX P/S may not be the best thing.  But if your problem is crappy P/S's then it would be a better solution.

Get a dedicated power supply like this one:

Then get some 18g wire lead to barrel connectors from digikey.com

That should fix your problem.

Last I checked, a $30 ATX power supply has a bunch of extra cables sticking out of it, you can't adjust voltages ( for instance, maybe you want to run them at 5.2v), and the 5v rails are nowhere near 40A.

No.  You cut off the lead from one of the million dead bricks you have, splice the wire to a molex connector (which conveniently give out 12v and 5v, just use whichever your hub needs), job done.

I run three hubs off the same PSU I run my Blades off.  Two hubs run off 12V, one off 5V.  All three use the same barrel connector, so I have the leads well marked as to what voltage the barrel plug outputs.  I also used to run the TPLink router off the ATX PSU using the same method, though I now use a RPi running off one of the USB hubs.

Barrel plugs are almost always centre positive, so really all you need is a multimeter (you can get them for £5 if you don't have one), a soldering iron (a soldering kit is about £10), and a few molex splitter cables to cut up.

A 4 amp psu well not run 10 erupters.  You need a minimum of .500 amps per stick, your 4 amp psu's can do 8 sticks, running 10 sticks overloads the psu and causes erupter errors.

Wrong.  A 4A@2V PSU will give out close to 8A@5V assuming a reasonably efficient voltage conversion inside the hub.
