psu 8 pin cable(s)

[HardStroke]

i know that its recommended to use 2 separate 8 pin cable for the gpu but i u use one cable that splits to 2 8 pin connectors can that effect the stability of the gpu overclock?

or is it just up to the silicon and the gpu itself? (stuff like power limit and etc)

Using one connector from each cable is a tiny bit better than using both connectors on a single cable.

Because you have more wires between the power supply and the video card, there's less losses in the actual wires ( more wires, less current resistance) so the video card sees slightly higher voltage.

 

Voltage = Current x Resistance   ...so the lower you keep the current, the lower the voltage loss ... the resistance is constant and depends on thickness and length of the wire between power supply and video card.

You lower the current by adding wires.
