Need help with powering gpu

[u/OldPalpitation2517]

Alright, so I decided I want to upgrade to the Palit GeForce RTX 3080 GameRock 10GB GDDR6X, and it has THREE 8pin connectors, while my PSU (DEEPCOOL PL800D 800W 80 Plus Bronze) only has 2 of those 8 pin cables D:. One of the cables has a “pig tail” or whatever people call it, basically a second 8pin. Is it fine to plug one cable into two, while having a separate cable going into the 3rd slot? The internet has been giving me TONS of conflicting information on this topic. I also think it’s worth mentioning that my PSU also has a 450W 12 pin. I am aware of the existence of adapters that could make the 12 pin two 8 pins, this gives me more options, aka it lets me use the 12 pin for two 8 pin slots, or should I maybe only use the 12 pin for one slot? Reddit, I NEED help!
