Performance and Testing
As you know, I do not have the specialized equipment for PSU testing (which costs thousands of dollars). So the best way I could do test the PSU is by using what we’ve got. My testing method involves comparing the voltage and power consumption reading during idle and at full load. I know it’s not the most accurate method technically, but I think this simple method should provide some ideas of the performance of the power supply in terms of stability and power consumption.

The main thing to watch out for, is the fluctuation on the +12V line. If the +12V line drops to below 12V during full load or large fluctuations in the V readings … then we’re in trouble. The system may unstable and you might also get random reboots.
We used AIDA64 and simultaneously ran both CPU and GPU stress test which produces 100% load. We then checked the voltage readings on AIDA64, we were able to read the sensor onboard the Asus Z790-E Strix Gaming motherboard. We were able to take the readings of the total power consumption of the CPU and GPU.
Idle
Voltage readings taken from ADIA64 at idle
- +12V : 12.096V
- +5V : 5V
- +3V : 3.312V
Load
Voltage readings taken from ADIA64 under load
- +12V : 12.096 (No change)
- +5V : 5V (No change)
- +3V : 3.312V (No change)
When the CPU and GPU is at full load, the system is drawing a lot amount of power. As you can see the power consumption for the CPU is around 238.83W (peaking at 274.09W), while the GPU uses around 334.60W of power (peaking at 350.06W). Both the +12V and +3V was rock solid and didn’t drop one bit. And same goes for the +5V line.
Now lets move on to the Conclusion and Verdict!
