style="text-indent:25px">電源外殼能影響電磁波的屏蔽和電源的散熱性，電磁屏蔽效果不好會(huì)影響人們的身體健康：散熱效果不好會(huì)影響電源的壽命乃至硬件的壽命。因此電源的外殼好壞與否是非常關(guān)鍵的，目前市場上的電源一般都采用鍍鋅鋼板材質(zhì)，部分產(chǎn)品采用了全鋁材質(zhì)·電源外殼的板材如果過薄，防輻射效果會(huì)降低·一般情況下，用戶只需估一下電源的重量就可以分辨。質(zhì)量電源的用料較好，拿在手里感覺厚重、有分散熱片夠大且比較厚，一般都采用鋁或銅等材質(zhì)。并且采用的電源線比較粗，輸出電流損耗更?。毫淤|(zhì)電源采用的線纜較細(xì)，長時(shí)間使用后線纜容易老化并破裂，進(jìn)而可能引發(fā)安全。在電源的線材選擇上并不是越長越好，線材越長，轉(zhuǎn)換效率就會(huì)相應(yīng)降低，所以說電源線材長度還是選擇合適的比較好：另外還要看電源線材的接口是不是足夠，以免影響以后的升級(jí)。不過現(xiàn)在市場上出現(xiàn)了模組電源，可以任意選擇線材，這極大地方便了用戶。質(zhì)量電源的做工精細(xì)、風(fēng)扇轉(zhuǎn)速平穩(wěn)、無明顯噪聲，外殼標(biāo)簽上會(huì)詳細(xì)注明電源的主要性能指標(biāo)。</p><p
