I'm having an issue with my brand-new PC (less than a week old) that keeps shutting down unexpectedly while I'm playing demanding games. The shutdowns are instant with no error messages or blue screens—it's just a total power loss, and it only happens when the GPU is under load. I've experienced this multiple times while playing heavy titles like The Witcher 3 on Ultra settings. Here are my specs:
• GPU: MSI GeForce RTX 5070 Ti
• PSU: MSI MAG A850GL PCIE5 (850W, ATX 3.0, 80+ Gold)
• CPU: Ryzen 7800x3d
If anyone else has run into similar shutdown issues or has suggestions on what tests I should perform next, I'd really appreciate your insights!

It sounds like your power supply or GPU might be having issues. Just to clarify, are you using the native 12vhpwr cable that came with your PSU to connect to the GPU, or are you using an adapter? That's crucial to know!
I didn't use the 12 vhpwr cable. Could that be the culprit? I'm new to this and didn't see the shop use it during the build.
