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.
Efficiency Requirements for 80Plus Certification
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, but for some reason AIDA64 was unable to read the sensor onboard the ASRock Z790 Taichi motherboard. We may have to wait for an update for AIDA64 and come back on this. Still we were able to take the total power consumption of the CPU and GPU.
Load
Voltage readings taken from ADIA64 under load
- +12V : N/A (no reading)
- +5V : N/A (no reading)
- +3V : N/A (no reading)
Total power consumption (in wattage)
- CPU (Core i9-1300K) – 371.93W
- GPU (RTX 3090) – 338.38W
At full load for both CPU and GPU, the system is drawing a decent amount of power. As you can see the power consumption for the CPU is around 371.93W, while the GPU consumes around 338.38W of power.
We unable to take the reading for +12V, +5V and +3.3V. For some reason AIDA64 was unable to read the sensor onboard the ASRock Z790 Taichi motherboard. We may have to wait for an update for AIDA64 and come back on this.
Now lets move on to the Conclusion and Verdict!
