Need some clarification on getting a 5070ti and its power cables. My 3080 is using two pci-e cables. The Msi 5070ti I’m looking at has an adapter. Are these for 3 pci-e cables?
 
I recommend against getting an adapter. Get a new PSU that supports 12v-2x6 natively and may be get a 90 degree cable. If it has an adapter then it's either 2 pci-e to 12v-2x6 or 3 pci-e to 12v-2x6. Do not cheap out on adapter, do not plug a single pci-e cable with 2 8pin head into the adapter. Do not tug on the cables and do not make sharp bends with the cable. 12v-2x6 and the older 12 high power have very little margin for power and any lose pins in the head will likely cause a fire.
 
The adapter should be for 2x PCI-E cables to one 12VHPWR connection, the new standard on Nvidia cards.
 
Yes, it is. My 5060ti 16 GB model came with the adapter and it works fine. I wouldnt really worry about this until it's a 5080 and up GPU's IMHO, or if you plan on heavy or extreme OC for daily use. I would only do this if each PCIe cable has one connection per wire, not 2 on one cable.

5060ti 150-200watts
5070ti 260-300watts
5080 350-400watts
5090 550-600 watts

From what I have seen, only high-power cards have had cables melt ( I could be wrong ). Make sure you plug the cable in fully and don't have any extreme bends in the cable to avoid hotspots.

If they say it shouldn't have more than 2 PCIe cables to one adapter, two should work just fine for your use case. Each PCIe cable is 150 watts and a PCIe slot is good for 75watts givening you 375 watts, as long as you have a good PSU.

I’d probably play it safe with the cables as well, those connectors seem pretty picky from what I’ve seen.

The problem is that we know there's some kind of problem. All the testings on YT sometimes contradicts each other. We aren't quite sure if it's always user error or cable / connector quality.
