Hi guys and thanks for reading and any potential help!

so I bought this
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItemVersion&item=261376179469&view=all&tid=1357393808016
20 port 90w
the psu outputs 20v @4.5 amp

It will only power like 8 usb miners ( ants/yellowjackets)
I would like to upgrade it so I can populate all ports but am very unsure of what I need (which psu) to do it safely
 I found this and think it may work, just wanted to get advise from someone who may actually know and can give me a few pointers

Hi Guys!
  im looking for a command line to run block erupters, U1 ants and NF yellowjackets on BFGminer,  I need all to be detected by BFG miner and the ants over clocked to 2gh/s.

Thanks in advance!

I haven't seen any posts about using GUIMiner and USB asics. It is my miner of preference and was wondering if I could still use it
