Topic: can I use Ebay USB hub w/ 40a power supply? - page 2. (Read 4129 times)
I had two different 40 amp PSU that I tried and both failed. I do have two 20 amp PSU that are running 56 miners. I also started a blog with the links to the parts I bought. http://aurel57.blog.com/
not sure what size you need.

Yeah, I already looked at the connections. They look alright, but I'll keep an eye on them and monitor tems as well to see how it works out. Thanks.
I may wire the power supply to my Rosewill 10-port hubs as well, since it only allows 8 miners w/ stock supply. This should clean up the wires.
Lastly, anyone know where to get barrel plug leads? not ones where I have to solder all the wires, but complete leads? I would prefer not butchering the stock adapters, but I'll do that if I have to.

I was wondering, since the main issue seems to be insufficient power...
I have a 10-port ebay USB hub that came with a 5v 2a adapter. However, after a few minutes of mining on my Erupters (3 installed), one will stop working, and overall, there's a high HW error rate. two will work just fine though. So I'm thinking that the main issue is power.
Would it work if I wired these to a 5v 40a regulated power supply?

Most likely yes, but be careful with the cheaper hubs, they tend to be undersized for significant power draw. I am currently using a cheap hub with five BF1 usb miners but I had to solder the power wires directly to the pcb because the barrel jack was tiny and would've melted at 3+ amps of current.
I run 10 port hubs wired to an ATX psu's 5v rail that is also powering some BFL gear on the 12v rail. Keeps things tidy
