I came across a highly-rated PSU that doesn't feature a native 12V-2x6 socket on the PSU side, but it does include a Dual 8-pin to 12V-2x6 cable. I'm planning to pair this PSU with an RTX 5070 TI. I understand that the new 12V-2x6 connector on the GPU side is designed for better power sensing, but I'm curious if that function still works when I'm using the dual 8-pin connectors from the PSU. Additionally, are there any other downsides to not having that native 12V-2x6 socket on the PSU?

Honestly, I wouldn't stress over it. The PSU was designed that way for a reason, so it should work fine as is.
It won't make much of a difference. Both setups utilize 6 ground and 6 12V connections to the PSU. In fact, using the dual 8-pin configuration might be a bit safer since it splits the load across two connectors, meaning each group of three pins runs cooler. Just ensure you plug everything in securely; if there's going to be an issue, it could arise no matter which setup you use. The only notable add-on I've seen is from Asus on their top-tier models, which include per-pin current sensing—it sends alerts if it detects a serious imbalance, but it would’ve been better if they had a hardware cutoff instead of relying on software.
Thanks for the insight! This is the PSU I'm considering: Super Flower Leadex III Gold UP 850W. Is there anything else I should look out for?
I noticed the 5070 TI requires 3x 8-pin connections, but the PSU comes with a 2x8-pin-to-12V-2x6 cable. Does that mean I can't use the provided cable?
