囧 我也不知道該怎說 就台灣商人太強 cost down到極限
說白點 有些大陸設計的PSU還不一定比我們強(cost down..)
文書機我也是上650W以上3K附近PSU...

反正CM跟FSP別碰 海韻要看看 其實台達電自己品牌的還算可以
Delta品質最好好像都是代工外銷版 但是不可能人人都買HCP 一顆8K

不要堅持低瓦數的話 真的可以考慮振華Leadex系列 550W
以前還蠻推Antec 不過後來他們找很多代工
各位現在要買可能請上Tom's Hardware查該型號代工廠還有架構來判定
基本上Antec只確定HCP是一定能買 當然價格就很殺

不然參考看看狼大有沒有什麼新測 很多PSU好像也出好幾年
架構就那些也玩不出新花樣 PSU就一成熟領域

考量450W跟CP值 文書機應該重C比P多
Golden Green HX(冰山金碟)應該會是不錯選擇
這些低階PSU要查review相當不容易 光要看到內部零件拆解就很少
這顆沒看到ripple但是同系列中高瓦數列在tier 2這階 應該不會太差
Antec低階那代工廠 咳咳..

當然這是從CP值上去看 簡單說就是要便宜又大碗
高瓦數當然P大於C 低瓦數則是C大於P 500W是交界點
其實之前有超高CP值小梅姐OCZ 但是賣切囉

Who's Who In Power Supplies, 2014: Brands Vs. Manufacturers

PSU tier list 2.0

這兩篇雖然是老文 但是還是很有用 國外網友推薦也很中肯
CP值見仁見智 主要是當地跟TW售價有差
橘色個人看法 勿筆戰 大家想法不同 想V就V 你爽就好 請回歸專業
海盜船台灣應該也是能買到 比較不好買

Tier One
The highest quality and most stable Power Supply Units available. Protected by industrial grade protection circuitry and can output wattage at a rated maximum temperature of 50°C or below. These units are also Haswell certified, meaning they can cope with the C6 and C7 sleep states of 0.05Amps without triggering the under-current protection switch. May even go over labelled wattage and still work until it safely shuts down.
