===============================================================================

nVIDIA GeForce GTX 650 Ti 由於是對應入門進階市場，
因此發布的當下各家AIC廠也同時推出各種自製版/超頻版產品。
主機板/顯卡大廠華碩首波推出的是DirectCU II Top超頻版產品，
採用自行設計的Digi+VRM數位供電設計，並搭載DirectCU II散熱器，
可穩定超頻也有效增加散熱效率，以下我們進行開箱介紹與效能測試。

包裝與配件
外盒設計以3條血紅的爪痕強調顯示卡的威力，並標示產品名稱與散熱器模式

GTX 650 Ti的DirectCU II散熱器
與自家中高階的GTX 670/660Ti/660採用的SSU式熱導管排列不同，
使用3根熱導管單向延伸至鋁製散熱鰭片

熱導管直徑約為6mm

用料細節
PCB本體，以消光黑的方式呈現

GTX 650 Ti的GPU本體，採用GK106-220-A1晶片
http://picx.xfastest.com/elvis/Graphic/ASUS/GTX650Ti-DC2T-1GD5/14.jpg

GDDR5顯示記憶體採用hynix H5GQ2H24MFR-R0C 2Gb的顆粒，共4顆構成1GB的容量
http://picx.xfastest.com/elvis/Graphic/ASUS/GTX650Ti-DC2T-1GD5/15.jpg

顯示訊號輸出端子內部設有金屬遮罩，降低訊號干擾的可能
http://picx.xfastest.com/elvis/Graphic/ASUS/GTX650Ti-DC2T-1GD5/16.jpg

Digi+VRM數位供電設計，4+1相供電

http://picx.xfastest.com/elvis/Graphic/ASUS/GTX650Ti-DC2T-1GD5/18.jpg

PCB背面可見類似記憶體的空焊點，也許有機會推出擁有2GB顯示記憶體的版本

PCI-E 6pin電源接頭的擺放方式與一般相反，
卡榫朝向PCB比較不會和導風罩互相干擾導致不方便拆卸，下方有電源接線指示的LED燈

總結
可以看到有了DirectCU II散熱器的加持，即使出廠超頻到1033MHz，
燒機溫度還是壓制在58?C，比公版低了非常多，整機最高耗電也只比公版高了9瓦。

美中不足的就是成也DC2敗也DC2，雖然散熱效果極佳，
但顯卡本體連同散熱器的長度實在是太長了，使用者在選購機殼時要特別注意。
不過對照華碩自家高一階的ENGTX560 DCII OC/2DI/1GD5，
GTX 650 Ti DirectCU II Top無論在DirectX 11性能或是功耗表現都好上許多，
期待華碩接下來推出卡身較短的產品，這樣才比能較符合主機小型化的市場潮流。
