為什麼買大瓦數電源供應器很愚蠢：英語精讀講義

High wattage power supplies are almost always a bad idea just due to being too expensive. 文法

大瓦數電源幾乎總是個壞主意，原因很簡單：太貴了。

I mean, sure,

我的意思是，當然，

that is of course as long as you're not doing some asinine projects,

前提是你不打算搞什麼瘋狂的專案，

such as seven gamers or eight gamers or 10 gamers one CPU.

像是「七人、八人或十人共用一顆 CPU」。

And even then,

就算那樣，

running seven freaking graphics cards,

運作七張誇張的顯示卡、

two 140 watt TDP CPUs,

兩顆 140 瓦 TDP 的 CPU、

and a small mountain of SSDs 慣用語

還有堆積如山的固態硬碟，

does legitimately take some solid wattage. 文法

確實需要相當大的瓦數。

Your standard gaming PC does not.

但你的標準遊戲電腦並不需要。

We have a number of videos

我們做過好幾支影片，

about not needing super high wattage power supplies,

講為什麼不需要超大瓦數的電源供應器，

but it became even more blatantly apparent

但這事變得更加顯而易見，

when our massively overkill setup of a high-end enthusiast 6850k 用詞

是因為當我們那套由高階發燒級 6850k

and dual GTX 1080s

和雙 GTX 1080 組成的極其效能過剩的配置，

drew just over a third of the wattage 用詞

消耗的功率僅略超三分之一，

while under heavy load 用詞

即便在重度負載下，

of a standard flagship power supply at 1200 watts.

也就相當於一個 1200 瓦標準旗艦電供的三分之一罷了。

What the shit?

什麼鬼？

Now I know,

好了，我知道，

I know,

我知道，

this isn't a new idea as I already said.

正如我之前所說，這不是什麼新觀點。

And I do have a fairly recent video on it,

我也確實做過一支距離現在不算遠的影片，

a super craptastic workshop video

一支爛到不行的工作室影片，

that you actually probably shouldn't bother watching 片語搭配

其實你大概沒必要去看，

because,

well,

呃，

it's garbage.

But be quiet!'s own Christoph Katzer has an article on this back from 2008

不過，be quiet! 的 Christoph Katzer 在 2008 年寫過一篇相關文章，

when he used to work with AnandTech, 文法

當時他還在 AnandTech 工作，

which is named Debunking Power Supply Myths

文章名叫《揭開電源供應器的迷思》，

and is actually a wonderful read.

讀起來非常棒。

In his final thoughts section,

在最後的總結部分，

he notes that few people, 文法

他指出很少有人，

if any,

如果有的話，

need more than an 850 watt power supply.

需要超過 850 瓦的電源。

That's from 2008.

那可是 2008 年。

Components have been getting progressively more and more efficient 文法

硬體組件一直在變得越來越高效，

this entire time,

一直以來都是如此，

and it doesn't stop there either. 表達脈絡

而且遠不止於此。

Power supplies have also been getting more efficient as well

電源供應器也變得更加高效了，

with the increasing abundance of highly rated 80 Plus versions across the board. 慣用語

各類高評級的 80 Plus 版本越來越普及。

Recommended power supply ratings for various computer components

各種電腦組件的建議電源額定功率

have started to react to this as well,

也開始順應這一趨勢，

which is great.

這很棒。

For example,

例如，

Zotac's crazy new AMP Extreme GTX 1080

索泰瘋狂的新款 AMP Extreme GTX 1080，

featuring an oversized two and a half slot cooler

配備了超大的兩槽半散熱器，

and ample amounts of power, 慣用語

以及充沛（AMPle）的電力，

sorry terrible joke,

抱歉，這諧音梗爛透了，

it only recommends a 500 watt power supply for the whole system.

它對整機的電源建議也僅為 500 瓦。

And Cooler Master's power supply calculator

而酷碼的電源計算機

seems to sing a similar tune. 慣用語

似乎也給出了類似的結果。

An i5 6600k with 16 gigs of RAM,

一台搭載 i5 6600k、16GB 記憶體、

a GTX 1070,

一張 GTX 1070、

an SSD, a hard drive,

一顆 SSD、一顆傳統硬碟、

a few USB devices,

幾個 USB 裝置、

a 240 mm all-in-one CPU cooler,

一個 240 毫米一體式 CPU 水冷、

additional three fans and gaming peripherals

額外三個風扇以及遊戲周邊的電腦，

all equated to an estimated grand total of 344 watts at load

在負載下的預估總功耗僅為 344 瓦，

and a recommended power supply of 394 watts.

建議的電源功率為 394 瓦。

But as I'm sure a few of you are acutely aware, 語氣意圖

但我相信你們中有些人敏銳地意識到，

this isn't the whole story 慣用語

這並不是全部真相，

and I wouldn't buy a 400 watt power supply for that computer any day.

而且無論如何我都不會為那台電腦買個 400 瓦的電供。

I just wouldn't really be comfortable with that.

我心裡實在不踏實。

Not only do the capacitors within a power supply 文法

電供裡的電容器不僅會

degrade slightly over time as it ages,

隨著時間推移出現輕微老化降級，

but there is also the efficiency curve to consider

而且還有效率曲線需要考慮，

and the overall build quality of the power supply.

以及電源的整體做工品質。

Each power supply's efficiency curve is more or less unique, 片語搭配

每款電供的效率曲線多少有些不同，

but let's use the curve of the Corsair 1200i for example.

但讓我們以海盜船 1200i 的曲線為例。

You can easily see the rise and the fall,

你可以清楚地看到它的起伏，

best in the middle,

中間段效率最高，

worst at excessively high and excessively low usages.

在極高和極低負載下效率最差。

Ideally, if your power bills are high,

理想情況下，如果你的電費很高，

you'd like to sit the load power of your system

你會希望把你系統的負載功率

at a highly efficient point in this curve,

控制在這條曲線的高效點上，

as long as that makes sense to offset the cost of the power supply 文法

只要這足以抵消

for that particular purpose.

為達成此特定目的而購買該電供的成本就行。

Another graph supplied by Corsair

海盜船提供的另一張圖表

and the reason I chose this power supply as the example

也是我選這款電源作為例子的原因，

is the fan noise graph.

就是它的風扇噪音圖表。

People going for absolutely silent systems 片語動詞

追求絕對靜音系統的人

can greatly benefit from low power usage components 片語搭配

能從低功耗組件中獲益良多，

because certain power supplies

因為某些電源

are able to go into a zero RPM fan mode

能夠進入風扇零轉速模式，

below certain amounts of wattage or usage.

當低於一定的瓦數或負載水準時。

At 30%,

在 30% 的負載下，

a 1200i would give you 360 watts

一個 1200i 就能給你提供 360 瓦

of zero RPM fan mode headroom, 用詞

的風扇零轉速餘裕，

plenty enough for a 6850k and a GTX 1080,

跑 6850k 和一張 GTX 1080 綽綽有餘，

which is a really high-end setup.

這已經是非常高階的配置了。

But don't use this video as an excuse 片語搭配

但是，別拿這支影片當藉口

to buy a cheap crappy power supply.

去買個便宜的垃圾電供。

Buy a good power supply.

買個好電供吧。

Skimping on this component is just fundamentally a bad idea. 片語動詞

在這個組件上省錢，本質上就是個壞主意。

That being said, 表達脈絡

話雖如此，

buying a 1200 watt power supply for your system

給你的系統買個 1200 瓦的電源，

when it will only peak at like 300 watts

但它峰值功耗只有大概 300 瓦左右，

and you don't care about zero RPM mode

而且你也不在乎零轉速模式，

is just lighting your money on fire. 慣用語

這完全就是在燒錢。

There's no point in doing that. 文法

這樣做毫無意義。

If you're worried about your choice of power supply,

如果你對如何選擇電源感到困惑，
