Does 3070 need 2 PCIe cables?

Answer: it's a single cable with two 6+2 pin plugs on it. It's recommended to use separate cables for each of the two 8 pin PCI-E power connectors on the card. However, the card is rated for a maximum power draw of 220W. A single 8 pin PCI-E power connection is spec'd to provide 150W.

Do I use 1 or 2 PCIe cables?

You can still use two cables—it works fine, too. But you won't get that setup's intended benefit unless you have a power supply with more than one 12V rail for a graphics card to pull electricity from. When you plug in two PCIe power cables from such a PSU, you'll draw power from each rail separately.

Can Power cables affect GPU performance?

Can you run GPU on one cable?

Yes, you can use both 6+2-pin or 8-pin connectors that are on the same cable (daisy-chained connectors) for most of the lower to medium power draw GPUs. But do not use daisy-chained connectors on power hungry GPUs. For 3090 rated at 350W you should use 3 individual PCIe cables if it has 3 connectors.

Can I split a PCIe cable for GPU?

In general, you should tend to avoid using split or pigtail PSU cables to connect a 2 pin graphics card. These cables might not be able to deliver the peak power that your graphics card needs, which can crash your computer or even brick your GPU.
