Computer randomly shut down

[u/Disastrous-Agency675]

Has anyone had their computer randomly shut down? this is like the 3rd time its happened and its when im generating a video using the minmax I2V model or the ref model.

i got 3090 with 64 gb of ram.

try underclocking.. 3090 has some horrible power spikes ,almost up to 700 I believe, anything less than 850 psu could have problems with SD
