Sorry, I didn’t catch your reply. My 3090 uses two cords, and it does experience random power surges.
Apologies for missing your reply earlier. It seems the PSU produces a buzzing sound when it activates. To determine the card's power draw, you can use a suitable monitoring tool or test under load conditions.
MSI Afterburner and EVGA Precision X1 can track GPU power usage. It’s likely your graphics card is drawing excessive current, exceeding what your power supply can handle, triggering its overcurrent protection and shutting down the system to avoid harming parts. The recommended fix is to purchase a power supply rated for higher wattage to cover these spikes.
@Crunchy Dragon aligns with my initial ideas. I’ll check the power draw if I can estimate it, then get back. The setup I’m using is a 1000 watt power supply. How much more should I expect? In Remnant 2 capped at 80 fps, it handled 250 watts heavily modded Skyrim at 100 fps (368 watts), and my CPU was nearly maxed out. Doom Eternal ran around 100 watts. It looks like pushing more FPS increases power consumption significantly, but I don’t want to cap my FPS with a 3090 to 85. With the current configuration, rendering in Blender should still be solid.
It seems you're looking for advice on power requirements. You mentioned that around 1200W should be enough, but you're open to 1300W if you need a bit more capacity.
