High resolution measurements in the ATX 3.0 range under 1 ms
However, because I still want to know exactly with the RTX 4060, I resolve the whole thing once even higher and take 20 ms as the total runtime. The intervals of 10 microseconds can just be measured sensibly and we also see the voltage as a gray curve here, whose average value is clearly above 12 volts, but which nevertheless still alternates a bit within the permissible range. I already wrote something about ATX 3.0 and the voltages.
If you then convert that to the power consumption in watts, then you get this picture:
I did the whole thing again for the torture loop, where we can admire the regular drops. First, the currents again, but they still have lots of weird, sporadically recurring drops in each rise. This looks like a violent hiccup before the power is really throttled back shortly after.
And then total wattage again:
Power supply recommendation
Now we come to the point that completely reduces the expected sensation of exploding power supplies to absurdity. So you should always stay well below 400 watts even together with the CPU, if you count up to 10 ms. Because it is what the power supplies still “see”. With a bit of reserve, you can get by with 450 to 500 watts, depending on the peripherals.
In this respect, I also formulate my power supply recommendation for the GeForce RTX 4060 that a modern 500 watt Gold or Platinum power supply should be sufficient. If you want to overclock, you don’t really have to budget much more, which is especially true for the board partner cards.
