I'm curious about whether it's safe to use two connectors from the same power supply cable to power my GPU. Are there any risks or considerations I should know about?

Using two plugs from one cable can work, especially if the PSU is built for it. For instance, older 6-pin connectors handle 75W each, while 8-pin connectors are good for 150W. If you're using newer high-power connectors, those can handle 600W, but there's less safety margin. For high-end cards, it’s best to have dedicated cables for optimal safety.
It's generally recommended to use separate cables if you can. This reduces the load on each cable and adds redundancy, which is always a safer bet. If you have two connectors on one cable, the PSU designates that it can handle the combined current, but spreading the load is still better.
That’s true! Even manufacturers suggest using single wires whenever possible for added safety.
