I have similar prob
can someone show me how to "join" 2 or more psu?
or give me the link
TIA
http://www.add2psu.com/I'm using one now, works like a champ.
I usually steer people away from DUal PSUs just because of how many problems I've seen with people getting them properly working, but that looks pretty sweet actually. Simple, no fuss, no muss, and seems like it should work just fine. I may recommend that (and maybe even try it myself some day

)
