[hpsdr] 5VDC Power Supply connections

[Maximo EA1DDO_HK1DX]

Hi,

I have almost ready a 5 VDC linear power supply to my HPSDR (for now just Mercury and Metis).
But I am not sure about ATX Molex connections.
On the 20 pin Molex ATX connector, there are four pins with +5VDC, pins 4, 16, 19 and 20.
For ground connection are seven pins; 3, 5, 7, 13, 15, 16, and 17.

Do I have to bridge all four positives together? or Can I apply +5VDC to just one? 
I mean, Are the four positives bridged on the Atlas? or Should I bridge them externally?

Same for the seven ground pins.

Thank you.
