有一位網友送來了一顆TFX電源供應器,表示是在淘寶上買的,接上他的配備有異常(高頻
音/負載下斷電等),請在下幫忙檢查看看
拿到後看到標籤,喔?是台達的,還是450W 80PLUS銅牌認證機種,只是標籤看起來怪怪的
,一般台達非消費市場機種很少用亮面印刷標籤,大多使用霧面及電腦印刷標籤,OEM款
也很少直接把80PLUS認證標誌貼紙貼在上面
https://i.imgur.com/muiv7Fi.jpg
台達一般非消費市場機種的標籤如下圖,因為是電腦印刷,所以上面的字與圖樣可以看出
一點鋸齒邊,底下的標籤也是霧面的,而且搜尋到的”DPS-450DB”型號家族都是PS/2規
格(常見的電腦電源尺寸),而非TFX的

拆開來看看,裡面的風扇是台達的
https://i.imgur.com/FpTgrHq.jpg
電路板,怎麼看起來也怪怪的,沒有台達該有的特色(變壓器與IC上會有台達自家型號)
https://i.imgur.com/OoLPuC1.jpg
輸出線路有被截斷及重接的痕跡,重接部分還只用絕緣膠帶(電火布)包覆,感覺更不單純

循著電路板上找更多訊息,看到虎標,心裡大概有個底了,這是一顆TIGER POWER偽冒成
台達的電源供應器
https://i.imgur.com/o7DjX0g.jpg
TIGER POWER為LEAD YEAR(力億企業)下的電源品牌,主要產品以OEM為主
https://i.imgur.com/3SYA9SC.jpg
輸入端EMI/全波整流子板上也有TIGER POWER與LEAD YEAR的字樣
https://i.imgur.com/I8MOCV7.jpg
從電路板上的編號”2582”去力億企業網站搜尋,推斷其本尊就是這款CG-TFX-2582,額
定輸出250W,與標籤上印的450W差異甚大,不過80PLUS銅牌認證倒是真的,此款定位給
POS/工業電腦/伺服器等使用,MTBF很長,從上面拆機看到的全日系電容及做工可以看出
本體品質也不算差,如果工作在250W以內的正常範圍,相信也是相當稱職
3.3V電流差異17A(偽)/18A(正),5V電流差異13A(偽)/20A(正),12V電流差異最大
16A-15A-8A(偽)/15A-15A(正),-12V電流差異0.8A(偽)/0.4A(正),5VSB兩者相同
從5V輸出電流量20A推斷這是一款比較重視5V輸出的舊規格電源供應器,用在目前以12V為
主的電腦設備,其結構設計可能會造成5V牽制12V輸出的狀況
https://i.imgur.com/TAPZGlA.jpg
至於為何會有被截斷的線組呢?原來是因為這款電源原本沒有PCIE 6P輸出,只有下面接腳
定義不同的6P(標示P3的接頭),所以將其線路截斷,並改接一條PCIE 6P線路上去
https://i.imgur.com/GAFa9Ls.jpg
只能說淘寶/拍賣買電源還是要慎選,尤其知名品牌的電源仿冒品很多,選的時候要張大
眼睛仔細看,假使沒有把握,還是尋求正規管道入手吧
報告完畢,謝謝收看
