What is the difference in performance of ATX 3.0 power supplies?

2023 04/10

One of the most powerful hardware inside the computer is the CPU, and the other is the graphics card. At present, the power of ordinary consumer CPU is generally between 65W-200W, and the power of CPU used by overclockers is generally between 200W-300W. The power demand of CPU is in a straight line, which is a steady-state power specification, and the rated power demand can be simply calculated. ATX Power Supply

What is the difference in performance of ATX 3.0 power supplies?

The graphics card is different from the CPU, as it is calculated in "frames", and the power consumption is not straight, but a PWM-like sawtooth wave.TFX SFX Power Supply
The power labeled by the graphics card is far from the actual power demand specifications, with the 30 series graphics cards being the worst hit, with the 3090 NVIDIA officially labeling the power as 350W, while the recommended power is 750W.Gaming Power Supply
ATX 2.x specification power supply, each power supply manufacturer on the power supply "dynamic peak" carrying capacity, "protection threshold" settings are different, so the same graphics card in a 750W power supply can be stable operation, in another 850W The power supply will protect the power off phenomenon.
