I recently got my hands on a Gigabyte RTX 5080 Gaming OC, and I noticed that the included adapter requires three 8-pin PCIe cables. The issue is that my Corsair TX750M PSU only has two 8-pin PCIe ports available. I've come across 12vhpwr adapters that use two 8-pin PCIe cables instead. Would that configuration work for my setup, or should I just invest in a new power supply? Since the Gaming OC can potentially draw up to 450W, I want to make sure I'm making a safe choice. Thanks in advance for your help!

Your PSU is actually capable of supporting up to four PCIe connectors. So with three cables, you should be good to go! Each cable can safely handle up to 288W, which is plenty for your needs. Just make sure to double-check your connections before firing everything up!
But he mentioned it only has 2 8-pin. The rest are 6-pin connections from what I saw on the specs.
