Is Master Lu's power consumption calculation accurate? Do you have a chart?

First: Master Lu's power consumption test is generally low, so the estimation is inaccurate and can only be used as a reference.

Second: If the power consumption is estimated to be 200W by software, then at least one power supply with rated power of 250W is needed. In other words, if the power consumption is estimated to be 280W, then at least one power supply with a rated power of 330W is needed to be safe. Otherwise, the rated power is low and the hardware power consumption is high, which will lead to various situations such as reduced hardware life, automatic shutdown, automatic restart, and unresponsiveness of programs.

Computer power consumption calculation

Formula: P=a×b×F×V2 (note that "2" in the formula refers to the square of the working voltage), where A and B are the coefficients (constants) related to the CPU architecture, F is the CPU working frequency, and V is the CPU working voltage, which can be deduced as follows: CPU current power = CPU default power × (current frequency/default frequency )× (current voltage/default voltage).

Computer power calculation motherboard (general): 25W-35W hard disk: 8-10wddr: 7.5-10wddr2: 2.5W optical drive: 23W network card: 7W sound card: 8W keyboard+mouse: 2.5w fan: 3W floppy drive: 4w1. 05 w 15lCPU is the main energy consumption of computer, and the thermal design power consumption (TDP is an index reflecting the calorific value of a processor). The full name of TDP in English is "Thermal Design Power", and the literal translation in Chinese is "Thermal Design Power Consumption". Some experts explained that processor power consumption = actual power consumption +TDP. The actual power of each processor seems inconclusive.
