You can take it, but there is a nuance

12 July 2025

Purchased in June 2025, at that time I had a Ricsa 6600, nothing special, 8 pin power. A month later, I bought a 5070ti and decided to power it through 12v 6x2, everything worked, but!!!! As soon as I started loading a game, the computer rebooted... (I inserted the connector all the way in, so there can't be a mistake here) I thought it might be the system, maybe a driver conflict, maybe I deleted something using DDU when I was cleaning the system from an AMD driver. But I remembered that this can happen when there's not enough power for the video card, when capacitors are bloated.

I decided to try the included adapter that came with the video card, and everything started working)))

You're almost there

Doesn't work as desired 12v 6x2
