High resolution measurements in the ATX 3.0 range under 1 ms
Because I still want to know it exactly, I resolve the whole thing even higher and take 20 ms as the total runtime. The intervals of 10 microseconds are still measurable and we can see the voltage here as a gray curve, 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’ll be fine with 550 watts.
In this respect, I also formulate my power supply recommendation for the GeForce RTX 4060 Ti as a modern 500-Watt Gold or Platinum power supply. If you want to overclock, you don’t really have to budget much more, which is especially true for the board partner cards.
