I just upgraded from an ASUS TUF 5070 Ti to an MSI Gaming Trio 5080, but honestly, I don't see much of a difference. I'm curious if I can run both the 5070 Ti and the 5080 at the same time, but my power supply doesn't have enough ports to support that. The 5070 Ti came with a 3v1 splitter cable that I could use. My power supply is an MSI MAG A1250GL Gen5 with a 12-pin 650W output for the 5080. I also have a 2v1 12V cable from my previous setup with a 4070 Ti. Would it be possible to use the 5070 Ti with that cable? Just to clarify, my PSU has 2 PCIe and 2 CPU power outputs, but I'm already using two ports for my Ryzen 9 9500X 3D processor, leaving me with only two available, which complicates things.

Honestly, there's not really a good reason to use two cards at the same time. What are you hoping to achieve with it? It might just overcomplicate things for you.
Didn’t your GPU come with an adapter? If you already have the cable from your previous GPU, maybe give it a shot. But make sure your PSU can handle the load first!

It did come with an adapter, but my PSU doesn't have enough ports for it.
