Do I need some kind of PSU if I plan on running 2-3 of these?
Price for shipping to Los Angeles, CA please
Using a computer PSU is not suitable because the voltage and amps are different, though someone in china has done it, you have to hack up your PSU and do lots of soldering to add capacitors and what not.
Not sure how using a 1000w gold or platinum computer PSU would be a problem here. Unless of course your only loading it with one or two of these miners and running them in scrypt mode only. I would think that the load from 10-20 of these would be more than enough to keep any good PC power supply happy.
The thing about the caps confuses me too. The output from good power supplies is about as clean as its going to get. Adding more caps on the output isnt going to do anything other then adding a capacative load to the supply.
But, bottom line is that these things are in fact very cool! If they can deliver the numbers quoted here we can finally be free of GPU mining once and for all.
