Power transients from high-end NVIDIA and AMD graphics cards can cause PC shutdowns. We explain what they are, measure them in the 30 series, and discuss their impact on the upcoming NVIDIA RTX 40 series GPUs (e.g. the rumored RTX 4080 and RTX 4090). NVIDIA’s RTX 3090 Ti consumes more power than any consumer GPU we’ve ever seen. The power draw of this card prompted investigation into how much power 3090s, 3080s, and even the venerable 1080 Ti consume. Transient power spikes from these cards can ask for 2x and more than the normal max power target. PSUs like the Seasonic PRIME line and the EVGA GA line might have trouble with these transients. We explain what these transient spikes are and how they impact PC building, and particularly, how much you need to plan ahead for future GPU purchases if this problem doesn’t get addressed by NVIDIA and AMD (or the PSU manufacturers) adequately.
