總的來說，買來一個電源首先看12V就對了，只要12V額定輸出大于你CPU+顯卡的比較大功率就說明這個電源能帶動你的電腦。不過這也只能說明能帶動，其他一些指標也是很重要的。 </p> <p> 銘牌上還有一點要注意，就是比較大輸出功率和額定輸出功率。額定輸出功率（或者叫實續(xù)負載，意為實際持續(xù)負載）指的是在這個功率以內(nèi)完全能夠正常工作沒問題。比較大輸出功率指的是這一路短時間能達到的比較大功率。如果你的電源寫的是額定輸出或者實續(xù)負載又是個***，那在這個數(shù)值內(nèi)是沒有問題的。如果是寫的比較大輸出或者MAX的話那應該留出更多的富裕。 </p> <p> <br /> </p> <p> <br /> </p><p> 路由器：除了一些前列路由器之外，絕大多數(shù)路由器適配器的DC頭都是5.5mm*2.5mm規(guī)格的。 </p> <p> 輸出電壓和電流也多在9V/0.6A~12V1A之間，此時只要非原裝（家里智能臺燈啊，其他電器，或者其他路由器）的適配器DC頭，輸出電壓和原裝適配器相同，而輸出電流大于或者等于原裝適配器的輸出電流，那就能放心使用。 </p> <p> 比如A適配器為9V/1A，B適配器為9V/0.6A，那么A完全兼容B。反之，也可以使用。只是需要注意，不能長時間使用，B可能會過熱，引起故障。 </p> <p> <br /> 我們經(jīng)常會收到一個關(guān)于如何找替代電源適配器的問題。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="廣東數(shù)碼產(chǎn)品電源供應商,電源"

1、標志清晰、信息完整。標記是指示使用者正確安裝、使用的重要信息，是確保使用者人身財產(chǎn)安全的一項非常基本的內(nèi)容。至少應包含以下信息：制造廠或經(jīng)銷商的名稱、商標或識別標記;機型代號或型號規(guī)格;電源性質(zhì);額定電源電壓范圍;輸出電壓范圍等。 </p> <p> 2、留意額定電源電壓范圍。因為我國市電電壓為220V，所以在選購適配器時，其額定電源電壓(即輸入電壓)范圍應包含220V，否則適配器不但不能正常使用，而且可能帶來燒毀、擊穿短路等不安全隱患。 </p> <p> 3、注意輸出的電壓性質(zhì)。電源適配器的輸出有交流和直流兩種，在選購時應選取符合預定使用需要的電壓類型。在電源適配器標志上，交流標識的符號為“～”，直流標識的符號為“—”。如果選擇輸出為直流的適配器，還應考慮輸出端子的正負極性與設(shè)備要求的一致性。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> <br />

動態(tài)性能指的是電源在負載大起大落時候的瞬間的電壓變動。這個包括電壓的變化和電壓的波形。在負載高低變化的一瞬間，電壓越穩(wěn)定越好，波形越接近一條直線越好。因為這個測試目前還沒有一個固定的標準。而且一般也遇不到這種情況，所以一般只是作為一個對比參考。 </p> <p> 5.保持時間 </p> <p> 保持時間指的是突然斷電后，各路電壓正常輸出的時間，這個時間主要是由主電容容量決定的。其主要目的是為了給一些硬件作出應急處理的時間，比如機械硬盤磁頭歸位，固態(tài)的掉電保護等等。一般來說主電容容量比較好大于每瓦0.5微法。廣東數(shù)碼產(chǎn)品電源供應商</p><p
