PowerColor PCS+ R9 380X Myst Testing:

Temperature Testing:

Temperature testing will be accomplished by loading the video card to 100% using Unigine Heaven Benchmark Version 4.0, with MSI Afterburner overclocking utility for temperature monitoring. I will be using a resolution of 1920 x 1080 using 8x AA and a five-run sequence to run the test, ensuring that the maximum thermal threshold is reached. The fan speed will be left in the control of the driver package and video card BIOS for the stock load test, with the fan moved to 100% to see the best possible cooling scenario for the overclocked load test. The idle test will involve a twenty-minute cooldown, with the fan speeds left on automatic in the stock speed testing and bumped up to 100% when running overclocked.

 

Settings

  • Monitoring with MSI Afterburner
  • Unigine Heaven 4.0 1920 x 1080 8x AA
  • 5-run sequence
  • 20-minute idle duration
  • Temperature measured in degrees Celsius

 

 

 
 

 

 

Power Consumption:

Power consumption of the system will be measured at both idle and loaded states, taking into account the peak voltage of the system with each video card installed. I will use Unigine Heaven Benchmark version 4.0 to put a load onto the GPU using the settings below. A fifteen-minute load test will be used to heat up the GPU, with the highest power usage recorded as the final result. The idle results will be measured after fifteen minutes of inactivity on the system with the lowest recorded power usage as the final result.

Settings

  • Unigine 4.0 Heaven Benchmark
  • 1920x1080 resolution
  • 8x AA
  • 15-minute load test
  • 15-minute idle test
  • Measurement is in watts

 

 

 
 

 

The thermal results delivered by PowerColor's PCS+ cooling system at stock speeds with the fans controlled by the card and driver are the lowest in the comparison field. PowerColor does the work to manage the thermals on its PCS+ line up. When overclocked and running the fans at 100%, the results are not as good by comparison due to the higher current load, but still are well within my expectations. Running the fans at 100% may have some running for the hills, but the fan noise is not objectionable and is no louder than a DVD drive when it spools up.

We know that AMD's power consumption results are going to be higher than the competition and that is born out in the testing. With a 190W TDP, the PCS+ R9 380X and the entire system hits pretty close to that number. Max power in the testing stayed below 300W total, which is less than I was expecting.
