CPU功率计算公式(国外英文资料) 1. know CPU power calculation formula, everything will be solved. P=a * b * F * V2 (note that the 2 refers to the working voltage of a, b square) is associated with the coefficient of CPU architecture, F (constant) is the working frequency of CPU V is CPU, the working voltage, which can be introduced: CPU = CPU * power current (the current default power the default frequency (x) frequency / voltage / current default voltage) 2. 2. computer power calculation The motherboard (general): 25W35W Hard disk: 810W DDR:7.510W DDR2:2.5W CD-ROM: 23W NIC: 7W Sound card: 8W Keyboard + mouse: 2.5W Fan: 3W Floppy drive: 4W 1394 device: 8W Built in Modem:6W Video card: 26W USB camera head: 2.5W Monitor 17CRT:80W 19CRT:105W 15LCD:35W 17LCD:44W 19LCD:50W Two, CPU CPU is the major energy hungry computer, and heat design power consumption (TDP is a measure of the heat release of a processor). TDPs full English name is Thermal Design Power, and the Chinese translation is heat design power consumption. The expert explained: processor power consumption is equal to the actual power consumption TDP. The actual power of the processors seems inconclusive. So, I checked the Internet and written materials overnight, without CPU actual power data. According to the physics knowledge above, CPU is used at the specified frequency, voltage and 100% full load: the actual power of the processor will be greater than or equal to the electric power. CPU in actual use, the CPU voltage, frequency settings will obviously increase and decrease the actual power of CPU (the following video card is the same), overclocking can increase power consumption exponentially. Oh, the usual standby and Internet access is actually very low, the computer no-load and full load power consumption is probably about 1 to 1.6. Therefore, considering the above factors, in calculating the power of the computer, in order to ensure the stable operation of the system, CPU power, graphics power should be in the foll
