@pganssle probably not with that power supply. The thing says 165W or whatever, but it'll spike.
I've done something similar with and RX7600 and a 450W supply. It was fine on 3D, but SDXL caused the overcurrent protection to trip. I've since upgraded to a 750W and seen short spikes to 300W+ just for the GPU.
@pganssle indeed. I was thankful that by going with the same brand (Corsair) I was able to just unplug everything at the power supply end, and then plug-in the new one.
@weebull Power supply seems like one of the cheaper things to upgrade (though maybe not one of the physically easiest ones, considering that it plugs into everything 😛
