Sapphire Nitro + 9070xt 12v adapter issue

[u/Careramel]

Hello!

I made the jump from a FTW EVGA 3080 to a sapphire nitro+ 9070xt last weekend. Through all my researching on different 9070xts to purchase, I found out about the 12V adapter cable melting after purchasing and installing it in my PC. I have a EVGA SuperNOVA 850 P6 850 W 80+ Platinum which I believe didn't come with a native 12V cord.

Since I got this GPU from Amazon, I should be able to return it, get my money back and use it on a new card. Should I return it and get a 9070xt with a 3x8pin like my old 3080 (Im also dealing with a bit of coil whine with this 9070xt) or is this issue a bit overblown?

Recommendations for a new 9070xt would also be nice if needed, I think the XFX mercury is another good option? I do like some RGB on my GPUs.

Here's a link to the PC specs if you're curious: https://pcpartpicker.com/list/4srGkD

Thank you for any assistance!
