Use 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

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

these been around since before jumperless OC/Motherboards

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

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.

Not once have I ever seen that, ever.

Finally found it: http://www.overclockers.com/2011-xtremesystems-ces-party-pictures/

It was GTX480 VRMs on a GTX580.

I've seen 8800GTX/Ultra VRMs on a GTX570 somewhere too, but that was because the VRM from the GTX570 popped.

Look at almost any 4-pin molex to 6-pin PCI-E adapter, as well as most mid-low end PSUs.

Not 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.

I 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:

Some of the 2x Molex to PCIe 6-pin adapters I've seen omit the second pin, which confirms that it can be removed when trying to cut costs.
