Upgrading your desktop PC’s graphics card can give your gaming a pretty big boost. It’s also a fairly easy thing to do. In fact, the hardest part is choosing the right card right card in the first place.

升级台式机的图形卡可以极大地促进您的游戏。 这也是一件相当容易的事情。 实际上，最困难的部分是首先选择正确的卡。

Your primary choice in graphics cards is between the two major makers of graphics chipsets—Nvidia and AMD. After narrowing that down, you’ll find that there are lots of card manufacturers making different cards based on either of those chipsets. In the end, there are hundreds of customized models available on the market. You’ll also need check for some basic compatibility issues with your PC. Does your motherboard have the right kind of slot for a modern graphics card? Will the card you want fit in your case? Can your power supply handle a card with higher power demands?

在图形卡中，您的主要选择是在两个主要的图形芯片组制造商之间— Nvidia和AMD。 缩小范围后，您会发现有很多卡制造商根据其中一个芯片组制造不同的卡。 最后，市场上有数百种定制模型。 您还需要检查PC的一些基本兼容性问题。 您的主板是否具有适合现代图形卡的插槽？ 您想要的卡适合您的情况吗？ 您的电源设备可以处理功率要求更高的卡吗？

Join us as we walk you through figuring those things out, narrowing down your card choices, and then physically installing your new card.

加入我们，我们将带您逐步解决这些问题，缩小卡的选择范围，然后实际安装新卡。

Note: Even though AMD makes both CPUs and graphics cards, you can use graphics cards based on either of the major chipsets on whatever CPU you’re running. In other words, you can run an NVIDIA card just fine on a PC with an AMD CPU.

注意 ：即使AMD同时生产CPU和图形卡，您也可以在运行的任何CPU上使用基于任一主要芯片组的图形卡。 换句话说，您可以在具有AMD CPU的PC上运行NVIDIA卡。

第一步：检查基本兼容性 (Step One: Check for Basic Compatibility)

Before you go shopping for a new graphics card, you need to limit the parameters of your search to the cards that your system can actually run. This isn’t as big a deal as you might think. If your computer has a free PCI-Express (PCI-E) slot and a decent power supply, it can probably run the lion’s share of modern graphics cards. Let’s start with that, why don’t we?

在购买新显卡之前，您需要将搜索参数限制为系统可以实际运行的显卡。 这并不像您想的那么重要。 如果您的计算机有一个空闲的PCI-Express(PCI-E)插槽和一个不错的电源，则它可能会运行大多数现代图形卡。 让我们开始吧，为什么不呢？

确保您的主板插槽类型正确 (Make Sure Your Motherboard Has the Right Kind of Slot)

Today’s graphics cards all use the PCI-E standard for plugging into your computer’s motherboard. This standardized slot gives high-speed access to your PC’s processor and RAM, and its position on the board allows easy access to the rear of the case, letting you plug one or more monitors directly into the card itself.

当今的图形卡都使用PCI-E标准插入计算机的主板。 该标准化插槽可让您高速访问PC的处理器和RAM，并且其在板上的位置使您可以轻松访问机箱后部，从而可以将一个或多个显示器直接插入卡本身。

Almost all modern graphics cards require a PCI-E x16 slot, and almost all motherboards that feature any full-sized PCI-E slots at all will have one. If you only have an x8-speed slot, that’ll work too, though performance on the most intense games might be a little limited. The important part is that you need a full-sized slot and not one that’s designed for smaller x1, x2, or x4 cards.

几乎所有现代图形卡都需要一个PCI-E x16插槽，几乎所有具有所有全尺寸PCI-E插槽的主板都将配备一个。 如果您只有x8速度插槽，那也可以使用，尽管在最激烈的游戏中的性能可能会受到一些限制。 重要的是您需要一个全尺寸的插槽，而不是为较小的x1，x2或x4卡设计的插槽。

The other thing to keep in mind is that a lot of the higher powered graphics cards are wide enough that they take up the space of two slots. If you’ve already got another type of card plugged in next to the slot you’ll use for your graphics card, you’ll need to take that space limitation into account.

要记住的另一件事是，许多更高功率的图形卡足够宽，足以占用两个插槽的空间。 如果您要在图形卡所使用的插槽旁边插入了另一种类型的卡，则需要考虑该空间限制。

确保卡适合您的情况 (Make Sure the Card Fits in Your Case)

Most full-sized tower cases can accommodate even the biggest graphics cards. If you have a smaller case (like a mid-tower or compact), you’ll have fewer choices.

大多数全尺寸塔式机箱甚至可以容纳最大的图形卡。 如果您的箱子较小(例如中塔或紧凑型)，则选择将少。

There are two primary issues here: card width and card length.

这里有两个主要问题：卡的宽度和卡的长度。

A lot of the higher powered graphics cards are wide enough that they take up the space of two slots. If you’ve already got another type of card plugged in next to the slot you’ll use for your graphics card, you’ll need to take that space limitation into account.

许多更高功率的图形卡足够宽，以至于占用两个插槽的空间。 如果您要在图形卡所使用的插槽旁边插入了另一种类型的卡，则需要考虑该空间限制。

The more thorny issue is card length. While low-end and mid-tier cards are generally short enough to fit most cases, more powerful cards tend to be much longer. And in some cases your available space might be further limited by where hard drives are installed, where cables are plugged into your motherboard, and how power cables are run.

棘手的问题是卡的长度。 虽然低端和中端卡通常足够短以适合大多数情况，但功能更强大的卡则往往更长。 在某些情况下，您的可用空间可能会受到安装硬盘驱动器的位置，主板上电缆的插入位置以及电源电缆的运行方式的进一步限制。

Also some very small PC cases might limit the height of the card you can use.

另外，某些非常小的PC机箱可能会限制您可以使用的卡的高度。

The easiest way to handle all this is to pop open your case and measure the space you have available. When you’re shopping online for cards, the specifications should list the measurements of the card.

处理所有这一切的最简单方法是弹开您的箱子并测量可用空间。 当您在线购物卡片时，规格应列出卡片的尺寸。

There’s also one more factor to consider: the card’s power inputs. Mid- and high-end cards require a dedicated electrical connection to the computer’s power supply. The plug for this cable is either on the top of the card, or on the end of it (the side opposite the monitor connections). You’ll usually need an extra half inch of so of clearance for this plug, in addition to the dimensions of the card itself.

还有一个需要考虑的因素：卡的电源输入。 中高端卡需要专用的电连接到计算机的电源。 该电缆的插头位于卡的顶部或一端(与显示器连接相反的一侧)。 除了卡本身的尺寸之外，您通常还需要为此插头留出半英寸的空隙。

And speaking of power…

谈到权力...

确保您的电源可以处理卡的电源要求 (Make Sure Your Power Supply Can Handle the Card’s Power Requirements)

You’ll need enough power coming from the power supply unit to feed the the new graphics card, in addition to all of your current computer components.

除了您当前使用的所有计算机组件之外，您还需要来自电源设备的足够电源为新的图形卡供电。

Most of the time this isn’t an issue—a relatively inexpensive 600-watt power supply can handle all but the most power-hungry graphics card plus all the standard PC components. But if you’re upgrading a inexpensive or compact desktop (or any non-gaming PC, really), you need to check your power supply.

在大多数情况下，这不是问题—相对便宜的600瓦电源可以处理除耗电最大的图形卡以及所有标准PC组件以外的所有图形。 但是，如果要升级便宜的或紧凑的台式机(实际上是任何非游戏PC)，则需要检查电源。

Specifications for graphics cards list their estimated power draw (or consumption) in watts. Make sure your power supply has at least that much available (with a 30-40w safety margin) before making your final choice. If it doesn’t, you need to choose a less powerful card or upgrade your power supply at the same time.

图形卡的规格列出了其估计的功耗(或功耗)(以瓦为单位)。 在做出最终选择之前，请确保您的电源至少具有足够的可用空间(安全裕度为30-40w)。 如果不是这样，则需要选择功能较弱的卡或同时升级电源。

If you’re not sure how much your other computer components are taking up, use this handy online calculator. Find the power draw of other components, add them all up, and see if there’s enough left in your power supply to comfortably operate your new card.

如果您不确定其他计算机组件的使用量 ，请使用此便捷的在线计算器 。 查找其他组件的功耗，将所有组件加总，然后查看电源中是否还有足够的空间来舒适地操作新卡。

If your current PSU can’t power the card you want, and you can’t upgrade the power supply, you’ll need to choose a less powerful card.

如果当前的PSU无法为所需的卡供电，并且无法升级电源，则需要选择功能较弱的卡。

The other thing you need to check is whether you have an available power cable of the right type. Some low-power cards can run from the electricity supplied by the motherboard alone, but most cards need a separate input straight from the power supply.

您需要检查的另一件事是是否有正确类型的可用电源线。 某些低功率卡只能靠主板提供的电力运行，但是大多数卡需要直接从电源输入。

Check the specifications on the card you’re choosing. If the card needs a separate input, it will require either a 6-pin or 8-pin plug. Some more powerful cards even require multiple connections. Make sure your power supply has the right cables and plug types for the card you want. On many modern power supplies, those plugs are even labeled PCI-E.

检查所选卡上的规格。 如果卡需要单独的输入，则需要6针或8针插头。 一些功能更强大的卡甚至需要多个连接。 确保您的电源设备具有适合您所需卡的正确电缆和插头类型。 在许多现代电源上，这些插头甚至都标有PCI-E。

If you don’t see the right types of plugs, but your power supply is otherwise powerful enough for your card, you may be able to find adapters (like these 6-pin to 8-pin adapters). There are also splitters (like these that can split a single 8-pin plug into two 6- or 8-pin plugs).

如果您没有看到正确的插头类型，但是您的电源足以为您的卡供电，则可以找到适配器(例如这些6针至8针适配器 )。 也有分离器(像这样的分离器，可以将一个8针插头拆分为两个6或8针插头 )。

确保可以将卡连接到显示器 (Make Sure You Can Connect a Card to Your Monitor)

Of course, you’ll need a monitor that can actually accept the video output of your new card. This usually isn’t a big deal—most new cards come with at least one DisplayPort, HDMI, and DVI connection. If your monitor doesn’t use any of those, adapter cables are cheap and plentiful.

当然，您需要一台可以实际接受新卡视频输出的监视器。 通常这没什么大不了的-大多数新卡都至少具有一个DisplayPort，HDMI和DVI连接 。 如果您的显示器不使用任何适配器适配器电缆，则价格便宜而且价格便宜。

如果我不能升级怎么办？ (What If I Can’t Upgrade?)

If you can’t upgrade your motherboard, power supply, or case to work with the specific graphics card you want, or you’re using a laptop and you want more power than is available, you also have the option of using an external graphics card enclosure. These are basically external boxes into which you can plug a PCI-E graphics card. They have their own power supply and a way plugging into a PC (usually via USB 3.0 or USB-C). Some come equipped with a graphics card already; some are empty enclosures for plugging in whatever card you want.

如果您无法升级主板，电源或机壳以使其与所需的特定图形卡一起使用，或者您使用的是笔记本电脑，并且想要的功率超过可用的功率，那么您还可以选择使用外部图形卡卡盒 。 这些基本上是外接盒，您可以在其中插入PCI-E图形卡。 它们具有自己的电源和插入PC的方式(通常通过USB 3.0或USB-C)。 有些已经配备了图形卡。 有些是空机箱，可插入所需的任何卡。

They aren’t an ideal solution. They do require an extra power outlet and a high-speed connection to your PC. Plus, they don’t offer the same level of performance as an internal card. In addition, these enclosures start at about $200 (without the graphics card itself). At that point, you have to start considering whether upgrading your PC or just building a low-cost gaming desktop is a better route to take. But for laptop owners or those who want a relatively easy way to add graphical power, they’re an interesting alternative.

它们不是理想的解决方案。 它们确实需要额外的电源插座，并且需要与PC进行高速连接。 另外，它们所提供的性能不如内置卡。 此外，这些外壳的起价约为200美元(不含显卡本身)。 此时，您必须开始考虑是升级PC还是仅构建低成本游戏台式机是更好的选择。 但是对于笔记本电脑所有者或希望以相对简单的方式添加图形功能的用户来说，它们是一个有趣的选择。

第二步：选择新卡 (Step Two: Choose Your New Card)

Once you’ve figured out what your PC can handle, it’s time to choose your new card. And there’s a lot to choose from. The first thing to take into account is your budget, and then you can narrow down from there.

确定了PC可以处理的功能之后，就该选择新卡了。 有很多选择。 首先要考虑的是您的预算，然后您可以从那里缩小预算。

设定预算 (Set Your Budget)

The graphics card market is fairly competitive, and as a general rule, the more money you spend, the more powerful the graphics card. Choose the best card that fits your budget.

显卡市场竞争相当激烈，通常，您花的钱越多，显卡的功能就越强大。 选择最适合您预算的卡。

Of course, there’s a difference in how much you can afford and how much you’ll want to actually spend. As a rule of thumb, any card above the $250-300 point (as long as it’s installed in a capable PC) should be able to handle almost any new game that comes out. You can spend more to get more power and more features—a typical goal is 60 frames per second in whatever type of game you like to play—but once you get past the $500-600 range, you’re looking at diminishing returns. The super-premium tier (the $800 and up cards), can handle pretty much any game at 60 frames per second on a typical 1080p monitor, with some going even faster or boosting resolutions to 4K or higher.

当然，您负担得起的费用和实际要花费的费用之间存在差异。 根据经验，任何价格在250-300美元以上的卡(只要安装在有能力的PC上)都应该能够处理几乎所有出现的新游戏。 您可以花更多的钱来获得更多的功能和更多的功能-通常的目标是在您喜欢玩的任何类型的游戏中每秒60帧-但是一旦您超过了$ 500-600的范围， 您就会发现收益递减 。 超高级层(800美元及以上的显卡)可以在典型的1080p显示器上以每秒60帧的速度处理几乎所有游戏，其中有些甚至更快，或者将分辨率提高到4K或更高。

Note: Due to the continuing influence of the cryptocurrency mining market, prices for graphics cards are somewhat inflated at the moment. Cards usually at the $300 level or below are more or less unaffected, but more powerful cards like the GTX 1070 or RX Vega (and higher) are seeing sticker prices hundreds of dollars above MSRP. To put it bluntly, it sucks.

注意：由于   由于加密货币采矿市场的持续影响，目前显卡价格有所上涨。 通常价格在300美元或以下的存储卡或多或少都不会受到影响，但是功能更强大的存储卡(如GTX 1070或RX Vega(及更高版本))的标价比建议零售价高出数百美元。 说穿了，很烂。

At lower price points (the $130-180 range), you can still play most games with a few compromises. You may need to lower the resolution setting or the graphical effects for newer games, but anything designed with a lower hardware tier in mind (like Rocket League or Overwatch) will still look great. And of course, older games and indie 2D titles will run just fine.

在较低的价格点(130-180美元的价格范围)，您仍然可以以一些折衷来玩大多数游戏。 对于较新的游戏，您可能需要降低分辨率设置或图形效果，但是任何设计时考虑到较低硬件层的东西(例如Rocket League或Overwatch )仍然看起来不错。 当然，较早的游戏和独立的2D游戏也可以正常运行。

查看评论和基准 (Check Reviews and Benchmarks)

Even in a particular budget range, you’ll find a lot of choices between different brands and configurations. Here’s where you’ll need to dive into the subtle differences to make your decisions.

即使在特定的预算范围内，您也会在不同的品牌和配置之间找到很多选择。 在这里，您需要深入细微的差异才能做出决定。

We can’t cover every card in this guide, but the web is your friend here. Read professional reviews of the cards you’re looking at, and check out user reviews from places like Amazon and Newegg. These reviews often point out little features or problems that you won’t read about elsewhere. You can also search for benchmarks to see how different cards compare, and sometimes how well those cards run particular games.

我们无法在本指南中涵盖所有信息卡，但网络是您的朋友。 阅读您要查看的卡片的专业评论，并从诸如Amazon和Newegg的地方查看用户评论。 这些评论通常会指出您在其他地方看不到的小功能或问题。 您还可以搜索基准，以查看不同牌的比较情况，有时还可以查看这些牌在特定游戏中的运行情况。

考虑一些额外的要点 (Consider a Few Additional Points)

A few other general points to consider:

其他需要考虑的一般要点：

• VR headsets like the Oculus Rift and HTC Vive need even more power than playing with a standard monitor, because they’re rendering two video streams at once. These headsets generally recommend a GTX 970 card or better.像Oculus Rift和HTC Vive这样的VR头戴设备需要比使用标准显示器播放更多的功能，因为它们一次渲染两个视频流。 这些耳机通常建议使用GTX 970卡或更好的卡。

• Choosing between AMD Radeon and NVIDIA GeForce cards isn’t typically all that important—both companies offer designs at various price points and compete well with each other. But they do have frame-syncing technologies that are incompatible with each other. These are software and hardware tools that reduce stuttering graphics and frame loss, making the hardware-intensive V-sync setting unnecessary. AMD uses FreeSync while NVIDIA uses G-Sync. Both require monitors that are explicitly compatible with each system, so if you have a FreeSync or G-Sync monitor, you definitely want to get an AMD or NVIDIA card, respectively.

  在AMD Radeon卡和NVIDIA GeForce卡之间进行选择通常并不那么重要-两家公司都以不同的价格提供设计并相互竞争。 但是它们确实具有彼此不兼容的帧同步技术。 这些是软件和硬件工具，可减少模糊的图形和帧丢失，从而无需进行硬件密集的垂直同步设置。 AMD使用FreeSync，而NVIDIA使用G-Sync 。 两者都需要与每个系统明确兼容的显示器，因此，如果您有FreeSync或G-Sync显示器，则肯定要分别获得AMD或NVIDIA卡。

• High-end gaming motherboards still offer multiple 16x PCI-slots, and both ATI and NVIDIA offer multiple-card connection setups (Crossfire and SLI, respectively). But in the last few years, advances in hardware have made these setups more or less unnecessary. You almost always see better gaming performance from a more expensive, more powerful single card than any combination of cards in Crossfire or SLI configurations.高端游戏主板仍提供多个16x PCI插槽，而ATI和NVIDIA均提供多卡连接设置(分别为Crossfire和SLI)。 但是在最近几年中，硬件的进步已使这些设置或多或少地变得不必要。 与Crossfire或SLI配置中的任何纸牌组合相比，使用更昂贵，更强大的单张纸，几乎总是可以看到更好的游戏性能。
• Almost all card manufacturers and retailers have surprisingly generous return policies. If you accidentally order the wrong card, you can usually return it within 14 days, so long as you keep your receipt (or confirmation email). Of course, this doesn’t apply if you buy your card from secondary markets like eBay or Craigslist.几乎所有卡制造商和零售商都出乎意料地提供了慷慨的退货政策。 如果您不小心订购了错误的卡，只要保留收据(或确认电子邮件)，通常可以在14天内将其退回。 当然，如果您从eBay或Craigslist等二级市场购买卡，这将不适用。

第三步：安装新卡 (Step Three: Install Your New Card)

After you finally get your new card, it’s time to plug that sucker in. And after the headache of sorting through reviews, choosing a new card, and parting with your money, this part is easy. You’ll need a cool, dry place to work with plenty of table or desk space, a Phillips-head screwdriver, and optionally an anti-static bracelet to protect your PC’s internal components.

最终获得新卡之后，就该插入该吸盘了。在经历了对评论进行分类，选择新卡并与您的钱分手之后，这部分工作变得很容易。 您需要在凉爽，干燥的地方工作，以留有足够的桌子或桌子空间，十字螺丝刀和可选的防静电手镯，以保护PC的内部组件。

Shut down your computer, unplug all the cables, and move the computer to your working area.

关闭计算机，拔掉所有电缆，然后将计算机移至工作区域。

Now, it’s time to remove the cover from the case. On most full-size PCs, you just need to remove a side panel so you can get to the card slots—usually on the left side of the PC if you’re facing its front. On some PCs, you’ll need to remove the whole case. And some manufacturers make this harder than others. When in doubt, check your manual or just search the web for how to take the case off your computer model.

现在，该从外壳上取下盖子了。 在大多数全尺寸PC上，您只需要卸下侧面板即可进入卡插槽-如果正面朝前，通常在PC的左侧。 在某些PC上，您需要删除整个机箱。 一些制造商比其他制造商更难。 如有疑问，请查阅手册或在网上搜索如何从计算机型号上取下机箱。

After getting the cover off, lay your PC on it’s side. You should now be looking down at your computer’s internals. If you have a current graphics card that you’re upgrading, you’ll need to remove it first. If not, skip to the next section.

卸下主机盖后，将PC侧放。 您现在应该低头看计算机的内部结构。 如果您有要升级的当前图形卡，则需要先将其删除。 如果不是，请跳至下一部分。

卸下现有的GPU (Removing An Existing GPU)

The graphics card should be pretty obvious. It’s plugged into one of the slots on the motherboard—usually the one farthest from you if you’re facing the bottom of the computer—and has its monitor connections sticking out the back of the PC. It may or may not have cables from the power supply plugged into it. And it may or may not have fans right on the card.

显卡应该非常明显。 它插入主板上的一个插槽中(如果您正对着计算机底部，通常是离您最远的插槽之一)，并且其显示器连接伸出PC的背面。 它可能插入或未插入电源电缆。 而且它可能会或可能不会在卡上安装风扇。

First, look for a power connection on the installed card. This will be a black plug with multiple pins, plugged into either the top or rear of the card. Unplug the cable and set it aside. If you don’t see one, don’t worry about it. It just means your existing card doesn’t need separate power.

首先，在已安装的卡上查找电源连接。 这将是一个带有多个针的黑色插头，该插头插入卡的顶部或背面。 拔下电缆并将其放在一旁。 如果您看不到它，请不要担心。 这仅表示您现有的卡不需要单独的电源。

Now, look at the metal piece where the graphics card touches the back of the PC. You’ll see one or two screws (depending on whether it’s a single or double slot card) securing it to the case. Remove these screws and set them aside—you’ll need them for the new card.

现在，看一下图形卡接触PC背面的金属片。 您会看到一个或两个螺钉(取决于是单插槽还是双插槽卡)将其固定到机箱上。 拧下这些螺钉并将它们放在一旁-新卡需要它们。

Now, this next part can get a little tricky, depending on how crowded your case is. Your card likely has a little plastic tab that holds it securely into the slot on your motherboard. You’ll need to reach under the card and push that tab to release the card. Sometimes, you push the tab down; sometimes to the side. And with bigger cards and more crowded cases, that tab can be hard to reach.

现在，这下一部分可能会有些棘手，具体取决于您的案件拥挤程度。 您的卡可能有一个小的塑料卡舌，可将其牢固地固定在主板上的插槽中。 您需要到达卡片下方，然后按该标签以释放卡片。 有时，您将标签向下推； 有时到一边。 而且，随着卡片的增加和案件的拥挤，很难找到该标签。

If you have trouble, just be patient and make sure not to force anything. You can also check YouTube for videos of people demonstrating this on different types of rigs.

如果遇到问题，请耐心等待，并确保不要强行施加任何压力。 您也可以在YouTube上查看有关在不同类型的钻机上进行演示的人们的视频。

Now, you’re ready to pull the card out. Gently grasp the card with your hand and pull up, starting with the side closest to the back of the case. It should come free easily. If it doesn’t, you probably didn’t get that plastic tab pushed all the way.

现在，您可以将卡取出了。 从最靠近外壳背面的一侧开始，轻轻地用手抓住卡片并向上拉。 它应该免费提供。 如果没有，您可能没有完全将塑料卡舌推入。

You’re now ready to plug in the new card, which is basically the same process in reverse.

现在，您可以插入新卡了，基本上相反。

安装新的GPU (Installing A New GPU)

If you just removed an existing card, you know where the new card goes. If you’re installing a card where there wasn’t one before, find the PCI-E x16 slot on your motherboard—check this article if you’re not sure which one it is. Remove the corresponding “blank” metal piece from the case’s expansion slot, or two if it’s a double-width card. You may need to remove some screws to do this—set them aside.

如果您只是删除现有卡，则知道新卡的去向。 如果要安装以前没有的卡，请在主板上找到PCI-E x16插槽- 如果不确定该卡是哪条 ，请查阅本文。 从机箱的扩展插槽中卸下相应的“空白”金属片，如果是双倍宽度的卡，则卸下两个。 为此，您可能需要卸下一些螺钉-将它们放在一边。

Gently slide your card into place on the PCI-E slot. As it’s going in, be sure to align the metal piece that connects with the case with the tab that accepts it.

轻轻将卡滑入PCI-E插槽中。 在进行过程中，请确保将与机壳连接的金属片与容纳它的卡舌对齐。

When it’s in and perpendicular to the motherboard, push down gently until you hear the plastic tab at the end of the PCI-E slot “pop” into place. You may need to push it a little with your finger to make sure it’s physically locked into the receiver slot on the card.

当它插入并垂直于主板时，轻轻向下推，直到听到PCI-E插槽“弹出”末端的塑料卡舌就位。 您可能需要用手指稍微推一下它，以确保它已物理锁定在卡上的接收器插槽中。

Next, use the screws you set aside to secure the graphics card to the metal piece at the back of the case.

接下来，使用预留的螺钉将图形卡固定到机箱背面的金属件上。

And finally, connect the power cable if your card requires one. Whether you’re using a 6-pin connector, an 8-pin, or multiple power connectors on a high-powered card, the plugs should only be able to fit in one way.

最后，如果您的卡需要一根，则连接电源线。 无论您是在大功率卡上使用6针连接器，8针还是多个电源连接器，插头都只能以一种方式安装。

Double check all the connections and screws to make sure they’re firmly in place, and then replace the side panel or case cover. You’re now ready to move your PC back to its usual spot, plug in all your power and data cables, and turn it on. Make sure to connect your monitor to your new graphics card, not to the video-out connection on the motherboard itself!

仔细检查所有连接和螺钉，确保它们牢固就位，然后重新装上侧面板或机箱盖。 现在您可以将PC移回原位，插入所有电源线和数据线，然后将其打开。 确保将显示器连接到新的图形卡，而不是主板本身的视频输出连接！

If your display is blank after turning everything on, go back through this guide—you may not have installed the card correctly. The most common troubleshooting problem is a card that’s not fully inserted into the PCI-E slot; double-check the plastic tab and make sure it can lock in place.

如果打开所有设备后显示屏均为空白，请重新阅读本指南-您可能未正确安装卡。 最常见的故障排除问题是未完全插入PCI-E插槽的卡。 仔细检查塑料卡舌，并确保其可以锁定到位。

Another cause for this happens when you’re installing a new card on a system where you previously used the internal graphics built into the PC’s motherboard. Most PCs automatically detect whether you’ve got a discrete video card installed and make it the default display. Some systems may not. Check your BIOS and you should find a setting that lets you set your default display.

当您在以前使用PC主板内置内部图形的系统上安装新卡时，发生此问题的另一个原因。 大多数PC会自动检测您是否已安装了独立的视频卡，并将其设置为默认显示。 有些系统可能没有。 检查您的BIOS ，您应该找到一个可以设置默认显示的设置。

If the monitor still isn’t showing the boot screen, you may have a more serious compatibility issue.

如果监视器仍未显示启动屏幕，则可能存在更严重的兼容性问题。

第四步：安装显卡驱动程序 (Step Four: Install Graphics Card Drivers)

When your PC starts, everything will probably look fine. Windows includes basic drivers for most video cards. To get the most out of your new card, though, you’ll need to download and install the correct drivers.

当您的PC启动时，一切看起来可能很好。 Windows包括大多数视频卡的基本驱动程序。 不过，要充分利用新卡，您需要下载并安装正确的驱动程序。

Luckily, this is pretty simple these days. NVIDIA and AMD both offer downloads directly on their website, separated into card and operating system directories. You’ll also find options for automatically detecting your card and showing you the drivers you need. Just select whichever ones apply to your system and download them in with your web browser. This might take a few minutes—the complete graphics suites are generally a few hundred megabytes.

幸运的是，这几天来这很简单。 NVIDIA和AMD都直接在其网站上提供下载，分为卡目录和操作系统目录。 您还将找到用于自动检测卡并向您显示所需驱动程序的选项。 只需选择适用于您系统的系统，然后使用网络浏览器将其下载。 这可能需要几分钟的时间-完整的图形套件通常只有几百兆字节。

You even have the option of installing apps from either company (NVIDIA’s GeForce Experience or AMD’s Gaming Evolved Client) that feature advanced options like keeping your drivers up-to-date and optimizing graphics settings for games.

您甚至可以选择安装两家公司(NVIDIA的GeForce Experience或AMD的Gaming Evolved Client)中的应用程序，这些应用程序具有高级选项，例如使驱动程序保持最新状态并优化游戏的图形设置 。
