Well...I`m considering making my Tagan into a modular effort. I`ve posted on an engineering forum about noise and signal loss at the terminals, am waiting for a reply. Guess this is what lack of money and too much caffeine does to ya.
Adding connectors is a bad, bad thing to do. In electronics and electric faults it is well known knowledge that most of the time the fault is with a connection. Avoid them at all costs. These modulars are for show purposes, and are not really functional - I know; I own one!
The U15 series..they come in 430, 480, 530 and 580W varieties. Still to find out who stocks them, but they exist... who was it that said if Tagan made modular PSUs they`d be perfect??!?
