I have the above PSU and got a new Videocard. Unfortunately i lost the box and specs for my PSU and need to know how many amps are on the dedicated PCI-E connector since my new card needs 30A on this rail....It has 2x12V rails with 18A each, but what's the Amperage on the dedicated PCI-E?

Anyone know?

Well he videocard doesn't need 30amps. The videocard manufacturere recomends 30amps on the 12v combined for the system. 30amps at 12v would 360watts.

IIRC that PSU has a combined 12v rating of 32 amps......so it exceeds the videocard manufacturers base recommendatiuon.
 
I know that but it has 2x12V rails and ONE dedicated 6 pin PCI-E power adapter. My question is not whether it can handle the videocard, my question is how many amps go through the dedicated 6 pin connector.....or if i need a splitter with 2x4 pin to comine my 2x12V rails.
 
Maybe my wording was confusing here.

What I'd like to know is the following:

- does the 6 pin PCI-E power connector on my PSU draw the current from ONE of the 12V rails (18A) or is it completely seperate from the circuitry and has the combined 36A available to it?

- If it does draw current from only ONE 12V rail, how do i know which rail it is?

On an ATX12v2.0 PSU 12v2 feeds the processor alone while 12v1 feeds everything else. 12v1 is capped at a total output of 18amps IIRC on that PSU. So your PCI-E card is fed by that 18amps minus whatever your drives and other 12v devices use.
 
Well, all this was a moot point since my new Videocard was DOA... :(
