Hi, i have two Neoware Eon thin clients, both with faulty power supplies. one clicks but will not start and the other just would not turn on after just switching off and will not work again. I have checked they are receiving 240v and that the fuse in the power supplies are good. no visible bad caps in either. The clicking one i may try to recap and see if it starts. But i would like to ask if i could replace the power supply with a power supply listed as " 12V 300W 24 Pin ATX Switch PSU For HTPC POS Mini ITX High Power Supply Module " if i spliced on the power connector to the motherboard.
