Hi,<br><br>I have almost ready a 5 VDC linear power supply to my HPSDR (for now just Mercury and Metis).<br>But I am not sure about ATX Molex connections.<br>On the 20 pin Molex ATX connector, there are four pins with +5VDC, pins 4, 16, 19 and 20.<br>For ground connection are seven pins; 3, 5, 7, 13, 15, 16, and 17.<br><br>Do I have to bridge all four positives together? or Can I apply +5VDC to just one? <br>I mean, Are the four positives bridged on the Atlas? or Should I bridge them externally?<br><br>Same for the seven ground pins.<br><br>Thank you.<br><br>73, Maximo - EA1DDO<br> </body>
