Sapphire R9 280X Toxic Testing:

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's Heaven Benchmark version 4.0 to put a load onto the GPU using the settings below. A 15-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 15 minutes of inactivity on the system with the lowest recorded power usage as the final result.


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

















Equipped with a trio of fans, it takes some extra juice to push the R9 280X Toxic. Under load the card is not the most power efficient of the group in any way, shape, or form. Well overclocked and over volted out of the box, you have to guess that the R9 280X is going to fall into that high performance category. In both the load tests the card was more efficient than only the GTX 780. Equipped with solid build components and an 8+2+2 phase power design, the PCB and VRM components are built to handle a large power load.
