Gaming loop in factory state
Now, the spikes start to climb quite neatly. The total power consumption of 378 watts at 12 volts is still quite good, but the load peaks increase a bit more. Almost 632 watts plus the measured almost 50 watts for motherboard and peripherals on all rails are simply too unreliable for all 500 and 550 watt power supplies here. It can work, but it doesn’t have to. Since the CPU is demanded more, the load peaks are already well above 200 watts without OC.

But there is more to it than that. The average value is 409 watts, which is roughly what you can measure with normal equipment. However, the relevant 20-ms spikes go up to 673 watts! This will then grill even the bravest voltage supplier below 600 watts.
Again, it’s worth looking at the entire run, which unfortunately swallows up some of the short load peaks due to compression. But it’s enough for the overview:
