![]() ![]() ![]() The two connectors per cable make sense with cards that don't use a lot of power, like let's say two GTX 1070 in SLI.Įach GTX 1070 consumes up to 150 watts, with around 40-50 watts taken from the pci-e x16 slot and 100-110 watts from the pci-e 8 pin connector, so a single cable with two connectors would handle just fine around 200 watts added up. The reason they're not going with 4 separate long cables from the power supply is to save money (because the wires cost money) and because there may not be room on the back of the power supply for additional connectors (in case of a modular power supply) So because of this, it's possible to put two connectors on one cable coming from the power supply, because the pairs of wires and the connector on the power supply side (if any) can handle 300 watts. Through both the pci-e 6 pin connector, or the pci-e 8 pin (or 6+2), power is sent to the video card through three pairs of wires.Įach pair of wires can transfer up to 9A of current, or 12v x 9 = ~ 110 watts, so in total up to 300 watts can be sent through each connector.įor safety reasons and for other reasons, the organization that made the pci-e standard set the rules that a video card may not take more than 75 watts through a 6pin connector, and more than 150 watts through a 8 pin connector.
