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 2.5 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 measured temperature recorded as the result. The idle results will be measured after 15 minutes of inactivity on the system. With dual-GPU setups, the two core temperatures will be averaged.


  • Unigine 2.5 Heaven Benchmark
  • 1920x1200 Resolution
  • 8x AA
  • 15-minute load test
  • 15-minute idle test
  • Measurement is in watts













The Sapphire HD 7750 ULTIMATE kept a nice low power draw, which is great for an HTPC. This is also something I was expecting considering the card draws all of its power through the PCIe slot!
