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.
Idle
Voltage readings taken from ADIA64 at idle
- +12V : 12.216V
- +5V : 5.050V
- +3V : 3.308V
Load
Voltage readings taken from ADIA64 under load
- +12V : 12.168V (-0.048 change)
- +5V : 5.030V (No change)
- +3V : 3.3V (-0.008 change)
At full load, you can see the maximum power consumption for the CPU is around 268.40W, while the GPU uses a total of 242.76W of power. That’s a total power draw of over 541W just for the CPU and graphics card alone.
During our tests, the +12V line dropped ever so slightly from 12.216 to 12.168V (-0.048), while the +3 line went from 3.308V to 3.3V (-0.008), which is negligible. For the +5V line, it was rock solid at 5.050V.
Now lets move on to the Conclusion and Verdict!
