PSU pinouts are they exchangable?

For Science!
Go to solution Solved by Jurrunio,

It doesnt matter which 12v source goes to which 12v input, as long as they are both 12v

This has probably been asked before, and I apologize for such a dumb question. In the process of custom sleeving cables, I was wondering if the pinouts of the PSUs are specific to the extent that specific 12V pins need to be paired up with a specific 12V pin on the otherwide..

 

In the case of the RM750X EPS cable, the 4 pins furthers away from the clip on the PSU are all 12V cables, and the 4 closest to the clip are grounds.

 

The Motherboard side expects the 4 pins closest to the clip to be 12V and the 4 pins away from the clip to be ground. Can any 12V pin connect to the the PSU side? Or is there some cosmic significance that pin 1 (12V) PSU side, goes to pin 5 (12 V) mobo side, and pin 2 (also 12V) goes to pin 6 of the motherboard (and so on).

 

Hope that makes sense, I can put pictures if it is unclear.

So a bit more googling seems to have netted me the answer (and Jurrunio just got it a second earlier). Basically this diagram depicts what I was wondering to be possible (source in link). And the answer seems to be "doesn't matter since the 12V is all on a single rail for the RM750X"

 

Need to read up more about multi-rail PSUs in case I encounter one in the future.....
