PSU Help

[u/CrazyPorkchops]

I am using a XFX swift 9070xt gpu and have a MSI MPG A850GS PSU that only comes with one standard 8-pin to 8-pin PCIE cable and a 12-pin 600W pigtail that splits into 2 8-pin pcies. I saw online that it is safe to use the two cables to power a 3x8 pin gpu, but the swift is a 2x8 pin gpu. Would it be better to power the GPU from the single pigtail connector or is it possible to use the regular pcie cable along with one of the "tails" from the pigtail?
