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
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 Gigabyte Z790M AORUS Elite AX ICE 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 : 5.060V
- +3V : 3.328V
Load
Voltage readings taken from ADIA64 under load
- +12V : 12.096V (no change)
- +5V : 4.980V (-0.80V)
- +3V : 3.364V (+0.36V)
Total power consumption (in wattage)
- CPU (Core i9-13900K) – Max: 310.80 W
- GPU (Radeon RX 7900 GRE) – Max: 201.04 W
At full load, using the Core i9-13900K processor along with the Radeon RX 7900GRE, the system drew a total of around 511.84W … 310.80W for the CPU and 201.04W for the GPU.
The +12V line was pretty stable at +12.096V and did not drop at all. For those who don’t know … if the 12V line drops below 11V, the system will become unstable and most likely crash.
As for the +5V line, it was pretty solid too remaining at a constant +4.980V. This did drop slightly from 5.060V. While the +3.3V increased slightly from +3.328V to +3.364V. Based on our overall tests, the KISS QUIET Silent G3 Power Supply is a rock solid choice.
Now lets move on to the Conclusion and Verdict!
