I'm building a new PC and recently got a 3080 Ti for a great price of $300. The GPU has three 8-pin power slots, but my power supply only has three 8-pin connectors available – two of these are already in use for my CPU and motherboard. However, my PSU does have two 12VHPWR slots. Can I use a 12VHPWR to three 8-pin cable to connect to my GPU, or what would you recommend?

You'll need three separate 8-pin connections for that powerful card. If you're using two of those for the CPU, you're running low on power. I'd recommend getting a higher-end PSU that has enough 8-pin outputs. You don’t want to risk stability issues with such a demanding GPU.
That's true! I thought my PSU was high-end too, but you might want to check its specs to see if it can really handle everything.
