I recently purchased a PNY 5070ti and installed it, but my PC won't boot. The motherboard shows a VGA error light. I've already tried a bunch of troubleshooting steps like clearing the CMOS, updating the BIOS, uninstalling and reinstalling graphic drivers, reseating the GPU, and forcing the PCIe generation settings. Here are some important details: I'm running Windows 10, my old GPU (2070s) still works fine, and I have a Ryzen 5 5600x CPU (which I'm planning to upgrade soon). The 5070ti doesn't seem to power on, but the rest of the system starts up. What else can I do before deciding to return the GPU? I want to make sure it's not a simple fix first. Thanks!

Make sure you're powering the 5070ti correctly! Are you using the 12vhpwr cable directly or an adapter? If you’re using an adapter, check how many PCIe cables are connected to it and how many it can take. It's crucial to have enough power for these cards to boot up correctly! Let me know what setup you have.

I'm using the adapter that came with the GPU, and I have two PCIe 8-pin connectors plugged into it.
