I've been experiencing random crashes on my PC after upgrading from an RTX 3070 to an RTX 4070 Ti. Here are my specs:
- CPU: i7-14700K
- GPU: RTX 4070 Ti (previously stable with RTX 3070)
- Motherboard: ASRock Z790 PG Riptide
- RAM: 32 GB DDR5-5200 (Neo Forza, tried XMP on and off)
- PSU: Apevia "1000W" 80+ Gold (not ATX 3.0)
- OS: Windows 11
The crashes occur mainly during gaming actions like loading levels, pausing, or even just sitting in a menu. Here's what happens when it crashes:
- The screen goes black.
- GPU fans spin up to 100%.
- The system freezes and becomes unresponsive.
- A hard reboot is required.
- The Event Viewer logs a Kernel-Power Event 41 with no specific error indication.
I've tried several troubleshooting steps, including different NVIDIA drivers, clean installs, adjusting BIOS settings, monitoring temperatures, and reseating my GPU and cables. My gut tells me this might be a power supply issue since the crashes typically occur during load spikes, not because of overheating. Before I think about replacing my GPU or motherboard, I'm wondering if swapping to a high-quality ATX 3.0 PSU could fix this. Has anyone else dealt with a similar issue?

Sounds like you're on the right track. Apevia PSUs are known for being unreliable. It's definitely worth considering a quality ATX 3.0 power supply that's Tier-A rated, especially for a high-demand GPU like the 4070 Ti. That could very well be the source of your crashing problems.
Totally agree! The tier list for PSUs shows that Apevia doesn't deliver the stability you need for modern GPUs. A good PSU could make a huge difference, especially with those power spikes you're mentioning. I had a similar problem with an older PSU before I upgraded, and it solved all my issues.
