What do you guys think of this.

http://dx.com/p/10-port-usb-2-0-hub-with-external-power-source-100-240v-ac-adapter-33189

Can you run a different but simple power supply, something with 5 volts but with 4amps, That should let you comfortably run 7 ea.

They list the psu as
- Comes with 100~240V US plug AC power adapter
- Output: 400mA

1 asic need 500mA or .5 amp.

I use Roswell RUB-500 10 port hubs, they have a 4 amp psu, enough for 8 miners.  I run 7 to have a .5 amp headroom.

I've seen 6 of the rhb500's connected to a single rhb500 and the single connected to a RPi, runs 64 miners with no problems. The single hub also held 4 miners.

I have more hubs and miners on the way, good way to waste money.

Have you even made ROI with 1 of your erupters?
I mean, a hub is mad expensive, you are killing ROI by buying em.
Better stick em in a PC and let that PC mine too = double profit.

That's what I did.  I just ordered a couple more that I am going to cut the wart off the cable and use a PC power supply to run.  I have a 5v5a brick driving one now and it is fine other than the brick getting warm.

I currently use the same 49-port hub shown above with great success. I got lucky and found it for much less than normal costs, but I can assure you that I have no problem using all 49 ports simultaneously. It is very nice because it spaces the erupters nicely for good airflow, can hang on the wall, and is not so large it gets in the way (much better than 8 hubs stacked up).

41 miners cost me 650, 4 Roswell hubs cost 60 at wholesale, had the Pi.  At current rates I figure 20 weeks before I see profit, it may never happen, I don't care, it's been fun.

I'm modding a old 500 watt psu to power the hubs so I can get rid of the damn wall warts.  I have a pair of 7950's I mine Litecoin with when not using my PC, that's about $3 a day or more.  Nice thing about the Pi is it churns away 24/7 on minimum watts.
