GTX980 level card: use 1 or 2 cables for pci-e connectors?
another attempt to settle this once & for all:
I've a GTX980 which has 2 pci-e connector & has a TDP of around 170W which I plan to overclock but only lightly
so question's in the title: use a single pcie cable or separate pcie cables to psu?
> another question: as a general rule when a card has 2 pcie connectors, is it ok to always use a single pcie cable no matter how much the card eats (even 300W cards) or is there a "threshold" beyond which 2 cables are necessary for safety?
> and another question: does the answer to the main question also depend on the PSU used (max wattage? quality? both?) in addition to the card's TDP?
> yet another question: what's the worst that can happen if a single cable is used in such a scenario?
