newtekie1Yeah, I remember seeing someone using the PWM cut off from an old 8800GTX to replace the one on, IIRC, a GTX570.

newtekie1Nope, go look up the spec, the 3rd +12v is optional on the 6-pin but required on the 8-pin. Like I said.:rolleyes:

And any PSU that uses 6+2 connectors, like your Galaxy, will have all 3 because the connector has to follow the 8-pin spec.



What I mean is that the middle +12v pin is often missing completely.

HybridChillerUse an VRM from a 8800gtx on a GTX570 ?

That really doesn't have any benefit.

But using VRM from 570 on a 8800gtx is good

Wile ENot once have I ever seen that, ever.

Wile ENot even on the mid-low psus I've seen. If the psu you are considering is like that, it's time to consider a different one.

newtekie1I never use these PSUs, I'm just stating they are out there, and the PCI-E standard states the middle pin is optional on a 6-pin and required on a 8-pin. Just because you've never seen one without the 3rd pin doesn't mean it is required by the standard, and doesn't mean connectors without it don't exist.:toast:
