Yes that is the 4 pin. And the current draw is very little I would think but I have no exact numbers for you.

thanks. do you think it needs less power than 30W? (in total for both 12V n 5V?)

certainly below 30 watts, probably more like half that.

Yeah I would think so too. Anyone able to measure total system power consumption with and without the card?

yes, that would be very useful to have exact numbers for currrent requirements for 12 and 5 - i am also wondering if the card really needs both voltages. maybe it needs only 12V?

if the molex is plugged in and the card draws power from it, does it also draw power from PCIe?

is external power obligatory or optional? can the card also work on power delivered only by PCIe?

Useful for what purpose?

it does draw power from both, it is required.

Since we are on the subject of power: The Logic power for the card is drawn from the PCI-E slot. However, the power for the analog amplification sections are drawn from the cleaner molex supply.

i am thinking about independent, external power supply with some linear characteristic, thats why power specification of the card discussed is of interest to me

maybe you could use your clout and connections to find out specific numbers for current draw for both the 12v and 5v lines-- i think there are lots of us who want to buy the card specifically to able to run it via an outboard, high quality linear power supply.

thanks!!!

I will see what I can find out As I said though this card has split supplies. I guess you would be talking about using the linear external supply to replace the molex supply?

Just get a Seasonic power supply. last time i measured one the 12v was 12.00v right on the money with no fluctuation shown on the multimeter. Plus they're really quiet!

with full respect, quiet in what sense? this is a switch mode power supply so it generates among other things electronic noise, EMI and RFI produced due to the current being switched on and off sharply.

I thought I read somewhere that good power supplies are like a power conditioner. And by quiet I mean less fan noise.
