我應該買幾大W牛至岩?上 google search 「psu calculator」 有一大堆計算器幫到你,不過通常呢D計算器你要預期佢會報大數少少,就算唔係基於商業原因,報大數你用左冇事,報細數搞到你行唔到會好大件事,咁梗係報大少少唔洗出事既好………基本上,如果你冇需要另外插電既 display card,亦唔係用 i7 咁堅既 CPU ,300~350W 真係乜都夠做。如果你要額外插電既 6pin+6pin display,玩埋 i7,建議 400~450W 夠玩。如果你又要超 i7,又要 6pin+8pin display,建議上 550W ,有突買個安心,超唔起都冇得賴~

如果你係玩更高階既牛,例如玩孖卡甚至 3/4 卡既話,就要留意 +12V 既 A 供應係咪夠力。點知隻牛 A 夠唔夠力?你上網 search 下各大牌子火牛既 spec,睇下相近 W 數牛既 A ,再睇睇自己眼前隻做個對比就知道。

揀既時候有咩要注意?首先要按自己能力,揀自己認為唔錯既牌子。你識得多D,自然多D牌子選擇。其次,睇荷包負擔能力同使用需要。我唔贊成響火牛度慳錢。冇錯火牛買到靚一靚部機都唔會快左,之但係你越係冇錢,通常就越係想D硬件長命用耐D,而火牛最容易令到你夢想幻滅。雞牛慳舊零水,隨時要你幾千蚊野陪葬,咁就因小失大。

如果負擔能力較低既話,我建議用中庸之道,低W數既唔同牌子之間唔買最貴,又唔買最平,買中間價既貨。唔好貪佢平平地又有呢樣果樣功能就走去買佢……

如果負擔能力較好,不過冇乜特別要求既話,建議都係買隻 450~500W 牛,方便日後升級,等第時D過氣貴 display 落價過陣都可以有平野執。亦可以選用有 80+ ,有 RoHS 同多 safety protection 既靚牛,用落安心又開心,又為環保出一分力。
另一方面,可以留意火牛既 operating temperature。香港始終係亞熱帶區,夏天隨時上 32~35℃ 完全唔出奇。就算你開冷氣到 23℃,機箱積熱到箱內溫度達 35℃ 係可能既,尤其是非下置式火牛設計。響負擔能力較好既情況下,揀隻 operating temperatur

電腦經常自動熄機,有時未必關火牛事既

可能係本身機箱內積聚太多塵,導致CPU散熱不良,(又或者係散熱膏問題)

CPU一過熱,此時電腦就會restart

另外仲要留意番你想換的火牛會唔會唔support你塊底板 因為插頭的pin會有唔同

要看看你其他硬件, 如果其他硬件的用電量是大的話, 就要考慮換個WATT 數較大的火牛了
