[轉貼] 微星要在Computex展奇怪的東西了 SSC

"Personally I just want to say, hurrah for MSI because it's a shame Nvidia didn't learn how to stop its GTX 200-series from making the coils inside a PSU squeal like a baby powered from a 230V source sooner.

After reporting the problem to Nvidia, we were greeted with denial - it was unable to replicate the problem - until we sent readouts from an oscilloscope, displaying the interference shooting back up the PCIe power connectors into the PSU.

MSI has solved the issue by researching and sourcing different chokes as part of its customised PCB power design for its Lightening series of graphics cards.

With a ten power phase design (up from six) on this GTX 275, the yellow chokes are not environmentally sealed copper coiled over ferrite cores - the whole thing is ferrite with the coil firmly sealed inside. For the size, this also increases the power density, affording better performance claimed MSI.

The disadvantage is that, if you already own a GTX 200-series graphics card and want to get rid of the annoying squealing, you'll have to buy a new card. If you haven't already bought a GTX 200-series card then you might want to hold off, but it's worth noting that the MSI Lightening GTX 260/275 series won't be that price competitive since it has a large bundle of unique features."

黃色奇怪Choke，號稱不會有高頻噪音了!

只有GPU的供電改SSC嗎?
VRAM的部分不需要改嗎?
對了SSC到底是啥東東阿
呼叫狼大
幫忙解說一下吧

SSC固態電感 (Solid State Choke)
微星 R4600 HDMI全系列的供電模組上，均採用了最新的SSC固態電感 (Solid State Choke)。而SSC固態電感是在同級顯卡中少見之高級用料，固態電容除了讓壽命更長，穩定度更高，還可避免傳統電感因高頻運作而發生的惱人噪音，對於想享受絕對純淨影音效果的影音發燒友，是一非常重要的特點。

這個?

但，說真的，就算這張卡多高級，一年半後也是淪落到被下一代巴好玩的命運....


看來看去，只有「商業噱頭」，用來增加「賣價」，如此而已。

擁有跳水冠軍稱號的微星 何來增加賣價的意圖 只是優惠消費者跟產品C/P值吧

我看法不同

我的顯示卡整天在摺疊

天天都聽到那高頻音 聽到都快發瘋了....

不知這與封閉﹝密閉﹞式電感差在哪裡？ :confused:

那是因為你有與眾不同的高級水冷....

以原廠扇來說光是運算時的狂爆風扇運轉聲就完全蓋過那高頻音:jolin:

一般環形/方形封閉電感是把漆包線在磁芯上纏繞，頂多用膠固定，但還是會有諧振產生噪音的問題。
SSC這玩意還蠻新鮮的，手上的資料還不多，最早是用在螢光燈安定器上，比起傳統要節能，效率更高。

我覺得這不錯耶
至少不會聽高頻聲抓狂
我會聽的到............
