在2005年11、12期上,我们给大家介绍了主板做工的辨别方法,本期的文章将为读者介绍显卡做工的辨别方法。虽然从基本元件上来看,显卡和主板都是以电容、电感、电阻这三大元件为主,不过在做工用料上却存在着另外的一套理论。如果各位想要了解这套理论,不妨与笔者在本期的这篇文章里一同研究。一、供电电路1.核心供电核心供电电路最能体现显卡做工,与主板上的CPU供电电路相同,显卡的核心供电电路同样是由电容、电感、场效应管(MOSFET管)这三大部分所组成。通常情况,数量较多的电容是供电品质的首要保障,至于电感和场效应管的数量通常只有一两个而已(图1),消费者可以根据元件
In November 11 and December 2005, we introduced the method of identifying the workmanship of the motherboard. This issue article will introduce the reader to the method of identifying the work of the graphics card. Although the basic components from the point of view, the graphics card and the motherboard are based on capacitance, inductance, resistance of the three major components, but in the work of materials there is another set of theories. If you want to understand this theory, we might as well with the author in this issue of this article to study together. First, the power supply circuit 1. The core power supply The core power supply circuit can best embody the graphics card work, and the CPU power supply circuit on the motherboard the same, the graphics core power supply circuit is also composed of capacitors, inductors, FETs composition. Usually, the larger number of capacitors is the primary guarantee of power quality, as the number of inductors and FETs are usually only one or two (Figure 1), consumers can according to components
