How to choose a suitable power consumed calculator?
Based on our previous discussions on CPU and overall power consumption calculation, you can choose a suitable power consumed calculator from these dimensions:
1、 Match your own usage scenario
Ordinary installation power selection: Priority should be given to tools with timely hardware database updates, such as Outervision power consumed calculator and Hangjia power consumed calculator, which can cover the vast majority of mainstream new hardware and directly provide recommended power wattage.
Professional overclocking/customized equipment: Choose tools that support custom overclocking parameters and fine multi device settings, such as Outervision's expert version, which can manually input CPU overclocking frequency, voltage, multi graphics card configuration, and other details for higher measurement accuracy.
Novice quick estimation: choose lightweight tools launched by domestic hardware manufacturers, such as the power consumed calculator built into the official account of Yingchi. The operating threshold is low, and the power consumption of basic accessories is automatically filled by default, instead of manually setting item by item.
Special scenarios such as embedded/FPGA: Choose a dedicated calculator exclusive to the corresponding hardware manufacturer, such as the Xilinx 7 series FPGA power consumed calculator, to adapt to specific hardware parameters and avoid adaptation deviations of general tools.
2、 Verify core competencies
Prioritize confirming whether the hardware database of the tool covers the CPU and graphics card model you are using, and also check if the tool automatically reserves a 20% -30% safety margin to avoid only outputting theoretical power consumption at full load, which cannot guarantee long-term stable operation of the power supply.
3、 Reference accuracy and additional functions
Priority should be given to tools with good reputation in actual testing, as the measurement results of such tools have a smaller deviation from the actual measurement values of external power meters; If there is a long-term measurement need, priority can be given to tools that come with electricity cost estimation and multi configuration comparison functions, which can simultaneously meet the needs of energy cost statistics.
