Looking at buying a power supply like the Meanwell switching power supply on ebay, which seems to be cheaper when you consider shipping to Canada, which is usually cheap from China vs. the US. Any one have any advice if I should risk it with a no name brand ($35.50 CDN) vs. the Meanwell ($57.50)? The 5V 60A unit should be pretty oversized for my needs, so buying a cheaper ac/dc transformer might be okay, so long as it not DOA.
My existing ATX is rated high enough but the voltage goes down to about 4 volts when loaded up and my USB antminers (2 gh/s) are running at about 0.75 amps each. I'd like to get the voltage up to 5.25 and get the amps down for better efficiency.
Any ideas for cable? I'm looking at a 24 pin 18AWG extension cable for under $10 then hacking it up for red & black wires only and installing the ring connectors. Can't find too many places that offer 16AWG wire for an extension cable. Might have a lead at "Shakmods" in the UK, but might be expensive to ship.
Any ideas for the power cord to the plug? I'm looking at cutting off the cable from a old power bar. Anyone know what the minimum wire size should be?
About the wires, there are 5 red and 8 black. Does anyone know if some of the black cables are not used by the hub? You would think the wires in would match the number of wire out. I just think that 8 black wires is overkill if there are 5 red going in.
Anyone know if the current will be balanced on all 5 reds? Is there some kind of 5V bus on the hub going in, or does each red wire feed specific ports only?
If anyone has any questions for me, I'd be happy to answer. I've got a raspberry pi running a bunch of U1 (~9) and U2 (~23) ant miners on the 49 port hub. I've also got a kill-a-watt and a usb meter with voltage and amps display.

Found a Meanwell SP-320-5 for $33 USD on ebay. Hopefully the voltage can be cranked up nicely.
Found a 18AWG for $750 USD also on ebay. Should be okay for the load.

Some of the cheaper 650 watt ATX PSUs have 45 amps on the 5 volts. That's more than enough for most uses of the 49 USB ports. Right? I mean, maybe not for 49 hex miners or something absurd. (Those should really have external power as well.)

I do have an older 500W ATX rated 47 Amps at 5V connected now with about 35 usb miners. My usb meter is showing 3.95 Volts at the usb and 150 Watts on the wall. Hashing fine, but getting a little scared if more the voltage will drop even more, causing the amps to go up causing more heat then is really necessary.
With a newer ATX, might get better voltage regulation but most newer ATX's have low 5A ratings.

Can't find too many places that offer 16AWG wire for an extension cable. Might have a lead at "Shakmods" in the UK, but might be expensive to ship.
I am getting a ATX LED ringed power cable mass produced, like the one Goodney shows how to make, so that everyone can use the LED power switchers. They are really cheap. I got 60A 5V one for $40 usd. Any ideas for the power cord to the plug? I'm looking at cutting off the cable from a old power bar. Anyone know what the minimum wire size should be?
16 gauge wire should be good, don't go lower than 18 gauge About the wires, there are 5 red and 8 black. Does anyone know if some of the black cables are not used by the hub? You would think the wires in would match the number of wire out. I just think that 8 black wires is overkill if there are 5 red going in.
Anyone know if the current will be balanced on all 5 reds? Is there some kind of 5V bus on the hub going in, or does each red wire feed specific ports only?
There is a 5v bus that balances the red wire feed. Taking a look at this picture, I can only see three x 5v pins that are actually used on the circuit, though i need to confirm this, they are pins 24, 22 and 21. All the other pins appear to be grounded only.

I ordered one but received a different unit that has 5V rated at 30A. The unit in the auction listing is model ATX-1000-N12S and is rated 5V 45A in the auction specs. The unit I received is model ATX-1000N. I'm in the process of returning this unit as the vendor has offered to replace it with the correct one listed in the auction. If you order one of these, just make certain the seller understands you want the correct unit. Update: Received the correct replacement PS from the vendor today.

Hello everybody, I am Zeta from Holland, and I run some small mining rigs as early February 2010. The problem started whit the fist batch of Block Erupter usb Miners I got in 2013 (100 of them), The 10 dollar USB Hubs from eBay give all kind of problems, power loops that damaged the computer electronic circuits. Not stable whit more that 10 miners. After that i Got some Drillbit and Fury miners, whit the anker hubs. The hubs managed to stay alive but were not stable at all. In January i Got some new miners, good for lot of amps at 5 volt (over-clocked), this time i ordered a $pecial Block-Erupter USB Hub whit 49 ports. The Next view days the whole hub is getting hot, and i needed extra cooling fans to keep the setup stable (Noooizzzz), after a week the usb died and I was broken beyond repair I got in touch with Eyeboot true this Great Forum, He told me I Needed a Industrial graded Hub from that many Amps and he sold me couple of His Orange USB hubs. This Hubs are GREAT! I loaded the new hub whit Overcooled Miners. Its Running 100% Stable, No burny smells, No magical smoke leaking out of the Electronics, Its running Stable as it can be. So If you looking for a Stable Hub, Go for The Eyeboot - Dipo-Elecronics 49 Port USB HUB. Let the Block-Erupter hubs, and the 10 dollar usb hubs from eBay for what it is, Save your selfs lot of frustration and go for the Industrial Grade ones. Thanks Eyeboot for all the help you give me whit my mining problems I had. My "out of the box" Video: https://www.youtube.com/watch?v=AOsCHuzzlfk&feature=gp-n-y

sent payment Payment received. Package sent today by one of my workers. I will get the tracking info for you shortly. It says shipping by EMS, that is usually really fast (like 5-7 days max). I think the 40 days might just be to cover the seller. Glad to hear you like the hub They are really durable and take at least 1-2 amps per port without burning down someone's house

I'd like to order a hub, but want to wait till the cables are ready and get both together.

I'd like to order a hub, but want to wait till the cables are ready and get both together. The cables will be ready in about 7 days We are using 18 gauge wire. Also making some modifications to the hub so that power on LED will still work even with the switcher cable.
