ATX 3.0 - the Best Power Supply Units for Your GeForce RTX 40 series
Case & Components
Fully Support for NVIDIA GeForce RTX 40 series Card
As NVIDIA continues to roll out new GeForce RTX 40 series graphics cards and push the boundaries of performance, it becomes increasingly crucial to have an exceptional power supply unit that can meet the power demands of NVDIA RTX 40 series cards.
ATX 3.0 is designed to accommodate higher power spikes of up to 2x the total system power excursion and 3x GPU power excursion that can handle the possible high power spike of the GeForce RTX 40 Series.
Why ATX 3.0 is recommenced? 2X Total Power Excursion for High Power Spike
We have conducted tests using various gaming and benchmarking software to see the power consumption and especially power spikes of NVIDIA GeForce RTX 40 series graphics cards. And here is the result.
You can see from the table that the power spike of NVIDIA GeForce RTX 40 graphics cards is much higher than what you might imagine. RTX 4090 hits peak 1199W with Hitman3 and this might trigger Over Power Protection (OPP) and shut down your system on an 850W ATX 2.0 power supply. Over Power Protection (OPP) might happen with RTX 4070 too on a 650W ATX 2.0 power supply when playing Red Dead Redemption 2 since the power spike hits 820W.
Most of the ATX 2.0 standard power supplies have the Over Power Protection (OPP) of 1.25 times the rated power. If you’re playing heavy workload games such as Cyberpunk 2077 and Hitman3 the system might consume more power than the OPP threshold, and the OPP might be triggered and shut down the system.
To completely avoid this situation, we recommend using ATX 3.0 PSUs that have 2x total Power Excursion for the RTX GeForce 40 Series cards. A PSU that meets the ATX3.0 standard allows for a 200% total power excursion, which is capable of covering any power peak situation in every scenario, be it game tests or heavy-load benchmark software. This ensures the stability of the system, after all, no one wants to face system issues during intense gaming sessions.
