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.
