对于很多DIY装机的朋友刚开始装机会觉得主板跳线可能是比机箱走线更令人头疼的一个问题，毕竟仅仅走线乱是不影响使用的，而跳线出错可能就会造成一些硬件无法使用甚至损坏，一个个排查问题反而更累心。其实只要弄明白其实挺简单的，今天小编在这里将对主板各个重要跳线接针进行介绍，下次碰到看一眼就能明白。
目前基本大部分主板的针脚数量和颜色都一样，有些时候根据品牌型号，针脚的位置和数量会有不同的变化。
开关重启：PWR(右下)
开关是跳线最为重要的一环，作为开关的针脚一般与众不同，两个针是一组，控制着电源灯、硬盘灯、开关和重启四个连线，这几个针不管什么主板都会在放一起，辨识度很高。
黄色是电源LED灯，对应Power LED跳线，注意正负极的方向，一般为左+，右-。
红色为硬盘LED灯，对应HDD LED跳线，注意正负极的方向，一般为左+，右-。
橘色是开关机针脚，对应Power SW跳线，不用理会正负极。
青色是重启针脚，对应RESET SW跳线，不用理会正负极。
开关针脚比较重要，根据不同的主板表现为Power SW、PW、PWR、PWRBTN、POWER以及ON/OFF，不要疑惑，以上这几个都是开关的意思，20HN举例的这款就是其中的PWR。
CPU散热器：CPU_FAN(右上、左右两边)
CPU散热器跳线同样比较重要的一方面，风扇的针脚也影响着是否能够顺利开机以及监控等方面，下图有三个散热的针脚，CPU_OPT、CPU_FAN以及AIO_PUPM，分别对应以下几个散热环境。
CPU_OPT：水冷水泵供电
CPU_FAN：CPU散热风扇供电
AIO_PUPM：专用水泵供电
其中CPU_FAN是每个主板必备的针脚，而CPU_OPT和AIO_ PUPM有些主板会没有。理论上这些接针是可以通用的，但是如果将CPU_FAN（4针）插到三针的水冷供电可能会造成控温功能失效，所以最好还是对应插线。
机箱USB：USB(右中、下中)
主板的USB接口除了I/O区域的那些，还有一部分以接针的形式放在了周围，这是为了给机箱前置USB接口提供跳线。USB接口主要分为USB 2.0、USB 3.0，较新的主板会有USB 3.1、3.2接口。
上图的USB 1112是USB 2.0的接口，后面的1112是编号，一般不用理会，特征为上5针下4针名字带USB的接口。
USB 3.0又名USB 3.1 Gen 1，这个接口明显的标志就是19针（多余的一针是为了防止插反），同时有些USB 3.0会在主板上标明为F_USB 3.0。
上图是USB 3.１接口，U31G2_E1其实是USB 3.1 Gen ２的缩写，也就是没改名的USB 3.１，这个接口代表的是机箱前置USB 3.1接口。
音频：AAFP(左下)
音频针脚是接机箱前面板麦克风和音频口，上４针下５针，有的主板还会命名为FP AUDIO等。
机箱风扇：CHA_FAN(右上、左中)
机箱风扇的针脚是CHA_FAN或SYS_FAN，这个针脚是给机箱风扇供电的接口，有一些主板会配备多个风扇接口，区别就是FAN后面的1、2编号。注意不要和CPU_FAN搞混。
灯光：RGB(右上)
主板的灯效名字为带有RGB，有电压提示，根据风扇的规格进行选择。
RGB灯针有两种，图中也可以看到左边的为3针，而右边的为4针，3针的光效可以通过编程让不同的灯组显示不同的颜色，不能正反双插。4针的光效是让LED灯都显示相同的光效，不支持正反双插，4针RGB灯针要注意正负极。（+12v上方带白框的底座为正极）
Note: The 3-pin interface is powered by 5V, while the 4-pin interface is powered by 12V. The two are not universal. Forcibly inserted and used may cause damage to the motherboard or lights!
Some cases have LED/RGB SW two-pin jumpers, which are connected to the lighting effect controller. If you have not purchased the controller separately, don't bother with it.
Buzzer alarm: SPEAKER (lower right)
The last is the alarm pin of the motherboard, called SPEAKER, which adopts a 4-pin design. After plugging it in, a sound prompt will appear if there is a problem with the motherboard. , it will not affect the use even if it is not plugged in.
The above is the method of wiring jumpers for computer installation. If there is a big difference with the text, please read the motherboard manual carefully or ask a master to come and deal with it.
