I inadvertantly found that I have another hub to add to the list. This 7 port from Amazon has handled 5 Erupters in a suprisingly good fashion:

It looks like the generic version of Tek Republic TUH-2700.

Where to begin...

I am still working on the 40A 5VDC power supply + cheap usb hub project, it was going well at first but crashed and burned on me, not literally but... meh no good yet, I have a few other things I want to try before writing it off completely.

Finally, my personal experience with the aitech 10 port has been different then described, it has run with cards in all 10 ports with no issues all weekend.

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.

About that Oimaster... did you have any luck with it? It sounded as though you wanted other people's input on its capabilities. I can't find its amperage anywhere, even on the official site:

Images Button on that product page - shows 5v @ 3.5A in two different spots.

Gaa, didn't see that! Was looking for specs text on all the sites that had them. Cheesy

I would like to power a 10 port hub with 5V 5A from my raidmax 850W psu. Which wires (from sata? or
Pci-e?) do I need to connect to the hub?

If you connect to molex, you need black wire for (-) and red wire for (+) for 5V
http://en.wikipedia.org/wiki/Molex
http://www.playtool.com/pages/psuconnectors/connectors.html

Make sure that you observe the expected polarity of the hub (they usually state either on the adapter or on the hub what's on the inner and outer contact)

Don't use SATA, unless you go by SATA-Molex and then connect to red/black, so that multiple SATA pins are properly aggregated.

PCI-e is 12 V (unless that's what your hub expects):
http://www.playtool.com/pages/psuconnectors/connectors.html#pciexpress

In theory, you should also be able to draw from ATX main:

Table updated with new Plugable info. I am also restructuring the OP to accommodate a section on AC adapters.

Quote from: Trongersoll on August 15, 2013, 03:10:42 PM

Today i got a Plugable 7 Port Hub and a Rosewill 10 port hub today. Although the Rosewill claims 4 amps, i couldn't get more then 6 Sticks to mine. and it wouldn't even let me daisy chain another Hub in the unused ports.

Just checked the Rosewill RHB-500 that you mentioned:
http://www.amazon.com/Rosewill-10-Port-High-Speed-RHB-500/dp/B004F38WT4/ref=sr_1_1?ie=UTF8&qid=1376766573&sr=8-1&keywords=rosewill+10+usb+hub
and was amazed to see that it looks exactly like ST-Lab U-500, which I reviewed earlier:
https://bitcointalksearch.org/topic/m.2937808

Mine also has 4A adapter, but it could run 8 BEs over a few hours, and is currently having 4 D-Link DUB-H7 chained off it, with 3 more on the way. Maybe yours has a faulty AD adapter?

im going to have to recommend this

http://www.aliexpress.com/item/Free-shipping-USB-BTC-Miner-pbx-private-branch-exchange-10-Port-USB-Bitcoin-Mine-Machine/1165698958.html

i have one of those cheapy pluggable usb 10 hubs and guess what today it just died on me well the powered part of died it still works using the usb to the computer but can only power one usb and the fan i will order another as i only paid £5.99 for it on ebay and order the product above

it can power 9 USB ASIC + My artic breeze fan = 3 Giga Hash it is USB 2.0 so when i set up my raspberry pi it will work on that too (currently just need a sd card + some time)

If anyone is using this item at the moment please let me know

Its called the OIMASTER FURTHER1 for the list.

Plugable 7 update. I awoke this morning to find green lights on 3 out of 7 erupters. Tried restarting cgminer, no joy. turned off cgminer, uplugged the power from the hub, restarted cgminer, plugged in the power to the hub. all working. I'm guessing that 7 erupters might be causing a marginal condition. If this happens again, i'll drop back to 6 erupters. Tongue

Was it USB 3.0 version?

yes 3.0 version.

I did this with an old ac adapter and and an ATX power supply for my Juiced hub before I sent it back. Just remember you may be limited by the gauge of the wire on the ac adapter and, at the very least, by the 11A rated molex connector.

Ah, so 2 hubs per molex connector, then.

My plan is to connect the cables from any eventual failed powerbrick to the 5V output on the Molex connectors, observing polarity. It works for motherboards, harddisks and all that stuff that gets connected directly to the PSU, so it should work for a hub. Or am I wrong? SolidBitShop, that's a question for you. Wink

Quite all right. I consider this derail to be relevant to the thread topic in general, as there are going to be people asking questions about replacement adapters in the near future... Roll Eyes

The thread took an interesting and relevant turn to replacement AC adapters. I will copy some of this info to a new section in the OP.

The powerbricks that drive D-Links are rather warm to the touch, so I pointer one of the fans to blow over them. If the worst comes to worst, and they start dying, I have the following contingency plan:

I have 3 old PSUs lying around.
Two ATX ones, where you have to short the green wire for them to start. Their 5V rails are rated 28A and 30A respectively.
I also have one AT PSU from the olden 486 days, where the PSU is turned on my the means of a physical switch (which was operated through a series of levers in the case) Cheesy

This has an 18A 5V rail.

My plan is to connect the cables from any eventual failed powerbrick to the 5V output on the Molex connectors, observing polarity. It works for motherboards, harddisks and all that stuff that gets connected directly to the PSU, so it should work for a hub. Or am I wrong? SolidBitShop, that's a question for you. Wink

Another note. When people start connecting those barrel connectors, pay attention to polarity that the hub expects. So have (+) on the inner connector, other can have (-).

Don't buy that 5V-8A-40W power supply above because I did and it's only good for 4 erupters 2Amps and this is because it's not a regulated power supply.
I'm not sure, but the other 5V-5A below it probably isn't regulated either.

For those wondering what's the difference between a regulated and a non-regulated...
with a non-regulated the more amps you draw the greater voltage drop.
with a regulated power supply there's minimal or no voltage drop, which is important with the erupters.

Very good info Grin

Thanks dyingdreams & merv77 !!

Was just hoping to get an adapter either brick or wallwart with more power,I have plenty of hubs.I hit Radio Shack & Best Buy today..........nothing worth while Sad

Gonna have to be online order.

Keep us posted to how you get along with yours dyingdreams.That one is in the US not China,which should get here ALOT faster than 2+ weeks Grin

I'm thinking the easist & cheapest route for me would be to get a bunch of these http://www.amazon.com/gp/product/B0058RLD9C/ref=oh_details_o00_s00_i00?ie=UTF8&psc=1

I would have to assume from your definition that it is regulated, since mine are running at near full capacity without any issues.

Soooo,useing 12 volt adapter on a 5 volt hub is ok?? Just asking,don't want to fry anything Wink

Trying to find 5 volt adapters is a real pain,ALL search engines throw 12/9/7.5 volt & any other volt in there,crazy Roll Eyes

It will fry your hub and, possibly, your Erupters.

I figured I'd ask Roll Eyes

Kinda thunk it Wink

Any hints to a 5 volt either 3amp or 4 amp adapters with the 5.5mm barrel connector??

I've been through the thread & most would require cutting & soldering or opening the USB hub,I just want to upgrade the adapter(wall wart or laptop style) Wink

I ordered 3 of these, from the same seller no less, and they are working well so far with no issues running 9 block erupters and 1 artic breeze. The brick does get kinda warm but not disconcertingly so.
