Question on PSU requirements

[sturmtruppe]

I recently rediscovered my 2nd pcie connector cable for my psu, so im no longer limited to gfx cards with only the 1 connector.

My question is, do the cards with 2 cost more to run (aka require considerably more juice) than cards with 1 connector? Is there somewhere that lists card's power consumption?

Yep, they need two connectors due to higher power requirements. The power usage can be found either on the manufacturer websites or on review sites of graphic cards.

Well the max power draw for each PCI-e is

PCI-e slot 75 Watts (6.25A)

6-pin cable supplies 75 Watts. (6.25A)
8-pin cable supplies 150 Watt (12.5A) (2 extra pins are grounding)

www.nivida.com has the max power use for the 200 series.
