I just bought and installed a PowerColor 9070xt Reaper graphics card, and I learned that it uses the 12v-2x6 power connector, which has a reputation for being a bit unstable. I'm wondering if I should be genuinely concerned about this or if I can mitigate the risk somehow, given I've done a fair amount of research before making my purchase.

As long as you plug it in properly and avoid bending the cable, the chances of it melting are pretty low. There have been some issues reported, but those usually stem from higher wattage cards like the 500-watt 5090s, not your 9070xt.
You're safe! With your GPU drawing only around 300-350 watts, it's unlikely you'll run into melting problems if you connect the cables correctly. Since you've done your homework on this, you're even less likely to face the issue.
Don't worry too much about daisy chaining; just make sure to unplug one of the CPU 8-pin connectors if you aren't overclocking it. Your GPU needs more power than the CPU in most setups.
I read that daisy chaining cables can be risky, but I'm confused about my setup. My PSU (Corsair RM850e) has three slots for PCIe—two of which I'm using for CPU power—and I'm left with one for PCIe. I used the 12v-2x6 connector that splits into two 6+2 connectors for my card, but is that okay? Some videos warn against this.
