標題是為了日後給其他人方便搜尋用的

已爬文leadex,techpowerup、technic3d等等稍加研讀過了
因為振華風向太亂了看不懂,打算爆預算直上海盜或EVGA
650w
https://www.techpowerup.com/reviews/Corsair/RM650i/10.html (2016年筆)
https://www.techpowerup.com/reviews/EVGA/SuperNOVA_G2_650/9.html (2015年筆)
750w

https://www.techpowerup.com/reviews/SuperFlower/SF-750F14MG/9.html (2014年筆)
下圖取自2016年海盜650w的測試,裡面也沒看到leadex 650w...

一開始看中EVGA
> 看到SF platforms得知給振華代工,找leadex的資料
> 因為找不到leadex 650w的測試圖表,所以用750w的EVGA vs Leadex相比較
> leadex這句The hold-up time failed to reach 16 ms (the minimum allowed limit)
> 看到同樣是evga supernova,650w的文章比750w晚了快18個月,是新架構改朝換代?
> 找650w區間的最新測試看relative performance,依然沒看到leadex 650w
> 注意到EVGA supernovaG2 650w的ripple圖比例比較小...頓失研究方向-->目前在這
然後跳轉到最後一頁看結論,節錄缺點部分總結如下:
●Leadex
1. 750w的hold-up time未達標,650w資料從缺
2. 750w體積偏大
3. 價格偏高(for 外國)
●EVGA
1. 750w體積篇大
2. 650w價格偏高,5VSB efficiency(這段我不懂,煩請解說")
●海盜650w RMi
1. No bypass relay for the NTC thermistor, which protects a unit against large
inrush currents
2. Short distance between peripheral connectors
3. Single EPS connector
海盜的專有名詞太多了請允許我直接轉貼,也煩請解說,謝謝....
************************************************************************
前情提要結束,接下來是發問
1. 爬文看到建議找LLC架構 + DC-DC,日系電容...LLC限定全橋嗎?
上面提到的(EVGA 650G2、750wG2,leadex 650w、750w、海盜650wRMi)這些都有嗎?
2. 其實推文中有看到安迪生(andyson)鈦金700w,這顆表現似乎很棒?
不過我查不到送修相關文章,有也是很久以前的...有經驗分享嗎?
3. leadex高人氣最大主因是cp值,如果無視這點,那建議用哪廠牌的?
因為替換的是低負載但一年只關機兩次的伺服器PSU,所以會考慮老化衰竭問題
4. EVGA同樣是750w而言,750 G1、750 G2、NEX750G 差別在哪?
打電話去EVGA問過了,台灣今年沒有白金級舖貨的計畫,所以只好用G2做比較了...
煩請指教,謝謝!
