普及电源知识（国外英文资料） A. preface People save their computers and they tend to put their budgets in the CPU, the graphics and so forth but do you find the importance of the power supply? Is this an important part of your computer input energy? Do you know? Your hybrid power supply is the cause of your computer systems instability! Speaking of power, lets talk about how many Ws power our computers need to use. Daily use, the power at the highest loads overworked general surface is no problem for a period of time, voltage fluctuation is more than 5% average surface is also no problem, but we will not necessarily surface after a period of time I will not have a problem, and, in the beginning, is only on the surface looks all right. 2. Power consumption of major parts [CPU] Sempron 2200 + typically 49.4 W (Model10) ~ 55.9 W (Model8), the maximum 62W Athlon64 Socket939 3000 + 67 w Celeron 4 1.7 G 1.7 W Celeron 4 2 g 52.8 W Celeron 4 2.4 G 2.4 W Celeron D 320 2.4 GHZ 320 w Celeron D 335J 2.8 G LGA 775 84W Pentium 4 2.4 C 66.2 W Pentium 4 2.8 A/E 89 w Pentium 4 520 2.8 G 84 w [hard] Western data Western data Seagate 7200.780g / 2M 12.5 W Seagate 7200.7 Plus / 160G / 8M, 12.5w Seagate 7200.7 SATA / 120G / 8M, 13.5 W Note that the power of the hard disk is read and read, and the power of the hard drive will be as high as 20-30w when the boot is initialized. These are obtained from the product datasheet, because of the time relationship, the other components are not being examined, directly referencing the online data [main] About 25W, and the integrated graphics card is 5-10w [memory] About 30 w DDR400 1024 m About 18 w DDR400 512 m DDR400 256 m about 10 w [video] ATI Radeon 9200SE and nVIDIA MX440, power consumption of 30W ATI Radeon 9800Pro and nVIDIA FX5900Ultra, the power consumption is around 60W GeForce 6800 GT power is about 55W S3 S3CE, 9550, 5200Ultra, 6200 AGP are estimated to be about 20-30w 6600 AGP is about 40W 9800SE AIW is estimated to be 60-80w GeForce 6800 - 40 w G
