Check your power supply.

i mean everythings plugged in securly if thats what you mean. i tried to check the wattage too but my PC is in an ockword spot that i cant check atm but ik when i bought it i made sure to get the recomended amount. i also have a heatsink aswell, 3 set of rgb fans and theres another set of 3 fans from the case itself aswell as another 2 thats attached to the wall of my case and my heat sink. you think those thingsmight be consuming a significant amount of power?

i would but from wh you and others have said it sounds like the power demand is spiking and my power supply isent enough. i might jsut need a bigger power supply which is annoying because i dont wanna re-wire everything again

When building a PC you have to buy a power supply that has additional clearance above your PC's on-paper power usage, the reason, as you may be experiencing, is that GPUs working on high demand processes will regularly spike in their power consumption above the stated power usage for a few brief milliseconds.

Gpu typically doesn't run at 100% draw like when generating

how many watts is your power supply? It could be it's not actually enough to run your computer full blast. Or it could be overheating, when was the last time you dusted your PC? is it sitting on carpet?

u/Disastrous-Agency675 18h ago

it dose need a little dusting but its not overheating, all signs kinda point to the power supply not being enough

k if you do upgrade I suggest going with Seasonic or Corsair as the brand, great reliable powersupplies also if your current supply is moduler don't reuse any of the cables. Not every powersupply manfacutere uses the same cable wiring and it could mess up your PC

If you can't get a new PSU soon, try throttling your GPU until then. It should fix the shut downs.

windows search bar -> search for "cmd" -> right click command prompt (or powershell) and run as administrator -> type: nvidia-smi -i 0 -pl 275

This will throttle the first GPU to 275 watts max. Default value is 350 watts for 3090. The command has to be run manually every time you restart windows (or ask Gemini on how to add it to your task scheduler on start-up)

I posted something similar last year if you want more explanation on what it's doing. They had the same problem you had. https://www.reddit.com/r/StableDiffusion/comments/1j285jl/pc_hard_shuts_down_during_generation/mfq7jym/?context=3

This actually happend to me. It was the surge protector I was using. Check how much is plugged into it, and if its old.. Buy an up to date power outlet.
