1  Bitcoin / Group buys / Re: [SOLD OUT] ASICMiner 49 port hubs +50 units! 1.75 BTC - Last batch on: November 06, 2013, 02:38:51 AM
Is there any consensus on a good Power supply to buy if you are running 40+ sticks.

I pulled an old 380w Raid Max out of my retired computer hardware box and have been running 43 block erupters and 2 usb fans. Seems like new ones on the low end are just not up to snuff. I realize it has something to do with the power going to the rails on new PSUs from reading through the forum, but my understanding of electronics is limited. Seems like a better idea to go digging through the garbage than online shopping at this point.

I've been using one of these for 2 months in my pc I built with no problems.
I bought another one last week to use with my hub, it handles 49 miners no problems. Been running it few days now. It's a really nice and cheap option.

Also, since these run on 5 volts, you need a psu that puts out enough amps at 5v. If your using an old 350 watt pc power supply I doubt it has enough amps at 5 volts. Theoretically you need at least 25 amps at 5 volts. But power supplies are always over rated and you don't want to run them at their max capacity. The one I listed above is 32 amps at 5 volts.

All setup and mining. It didn't work till I unplugged my 4 other 10 port hubs, than connected the 49 port hub with no miners in it. That got it too recognize most of the ports. Restarted again and switched usb ports on my desktop - finally recognized all the ports. That literally took a good 5 hours to set this damn thing up... Should of been so easy...

I can verify this PSU works with this hub as well.

Some progress. I was able to get ports 15-28 and ports 26-49 to work. All the other ports have power, but windows will not recognize any device on them...

I've now tried on three different systems with no results...

disconnect hub
reboot
connect hub
open device manager.
find that generic hub with an exclamation symbol
right click and choose update driver. let windows update the driver.
done.

When I try to update the driver, it just loads forever and never updates or progresses.
interesting bottom right corner... maybe that's contributing to an issue?
try a different system?

This is the second system I tried this hub on, both times I get the same error. The other system has a genuine copy of windows 7. I'm beginning to think it's the hub.

Got my hub today, can't get it to work in windows 7, any advice? Do I need certain drivers?

You have to put power to it first, and make sure you install the fuse also.

Not that stupid Smiley
Have sufficient power, and fused installed....

It keeps freezing on installing usb 2.0 hub [mtt]. It will process 4-5 of them and than freeze on the last one.

I'm not an electrician so I am not sure if this PSU will be suffiencent for my hub.

http://www.newegg.com/Product/Product.aspx?Item=N82E16817171033

Can someone look at it and let me know? If not I have to go buy one.

Thx

Technically you need around 24.5 amps at 5v. That has 25 amps at 5v... However you need some wiggle room, I wouldn't trust that to run a full 49 miner setup.. PSU's are often overrated in what kinda of power they actually make.

This is a good & cheap option for power, 32amps at 5v, I bought one for my pc build a couple weeks ago from here:
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=151146545085&ssPageName=STRK:MESE:IT

Are these back in stock yet? I'd like to purchase one.
that's an awesome PSU for this purpose... (based on listed specs and price)
I know, i'm ordering another one to go with this hub. I sent you a pm crazyguy.

Those numbers don't look bad to me.
Have you considered overclocking it?
