Computer host has leakage problem
Article Introduction:The internal cause of leakage in the casing of the computer host is the most common cause of leakage in the computer case. So what hardware inside the computer case is prone to leakage? In fact, this is not difficult to find. Just find the hardware that is in contact with the chassis. For example, the power supply is the most likely to cause leakage in the chassis. Another problem is that if the motherboard is not installed in place or some component pins touch the chassis shell, leakage is also likely to occur. One of the key causes of computer case leakage: power supply (the biggest culprit) Solution: Check whether the EMI circuit of the power supply is complete, and ensure that the plastic film or mica sheet between the spacing component and the metal shell of the power supply still has an insulating effect. At the same time, check whether the capacitor inside the power supply is normal to avoid problems such as explosion. If you find problems, you can make them yourself
