✔ 最佳答案
你之火牛之輸入電流為230v, 6a；但基於總輸出為200w，而w=v * a，即a= w / v，所以a=200/220 =0.9 a，即約為1 a。原則上火牛之輸入 / 輸出無可能相差那麼大，所以我們應只考慮輸出功率祇有1 a，你買3a, 220 v fuse應已足夠。但如果你定要根據說明而買，就要買7a(通常比顯示6a高些少)。但個人認為真是無可能輸入6a。

Agree with 001's answer, 220V 3A is safe enough for your PSU !
There is one more thing to be mention - if you are talking about the fuse inside the plug (插頭) of power cable, then a normal 13A BS fuse will suit your case...

應該要求供應商換過隻新火牛俾你!!
