PSU或电源单元^{(Power Supply Unit)}是任何计算机最重要的组件之一，因为它将电源分配给需要它运行的所有其他组件。你知道你必须有一个合格的电源单元^{(Power Supply Unit)}才能顺利使用电脑吗？如果您提供的功率低于要求，您的计算机可能无法正常运行。但是，您如何检查您的计算机需要多少电量^{(how do you check how much power is required for your computer)}？您的计算机使用多少瓦^(Watts)？

为了解决这个问题，这里有两个不同的PSU 或 SPMS 购买指南^{(PSU or SPMS buying guides)}或电源计算器^{(Power Supply Calculators)}，它们将计算您的计算机的能源使用量，这将帮助您为您的计算机系统购买完美的电源单元。

检查您的计算机^(Computer)需要多少电量

在选择这两个网站中的任何一个之前，您应该知道您将要运行什么。换句话说，您必须知道计算机的其他组件是什么。否则，您可能无法找到最佳匹配。

1] Cooler Master 电源计算器^{(Cooler Master Power Supply Calculator)}

Cooler Master在制作出色的^{(Cooler Master)}电源装置^{(Power Supply Unit)}方面是一个受欢迎的品牌。但是，他们的网站有一个很棒的工具，可以帮助用户找到他们的计算机需要多少电量才能正常运行。但是，如前所述，您需要在相应位置输入所有组件名称才能获得结果。

更具体地说，您需要输入以下详细信息：

• 计算机^(Computer)类型（台式机、服务器等）
• CPU制造商
• 套接字名称
• CPU 利用率
• RAM 数量和版本
• ^(Number)显卡数量和可能的型号
• ^(Number)HDD或SSD的数量及其可能的版本
• ^(Number)光驱数量及其版本
• 键盘^(Keyboard)和鼠标类型（还要提及它们是否用于游戏）
• PCI卡
• 你每天要运行这台电脑多少时间

点击“计算^(Calculate)”按钮后，该网站^{(this website)}将告诉您您的设置将消耗多少电量以及推荐的PSU瓦数。了解这一点后，您应该在市场上寻找可用的PSU^(PSUs)。

2] Outervision 电源计算器^{(Outervision Power Supply Calculator)}

这是另一个很棒的PSU购买指南，其用户界面与前一个几乎相同。它为那些对其硬件设置不太了解的用户提供了一个“基本”版本。^(Basic)他们还提供“专家^(Expert)”版本，让您输入机器的每一个细节。

基本版需要以下详细信息：^{(The Basic version requires the following details:)}

• 主板类型
• CPU 计数
• 内存计数
• 显卡^(Video)数量和可能的型号
• 存储数量和类型（HDD/SSD）
• 光驱数量和类型
• 监视器数量和大小
• 电脑使用时间
• 游戏/视频编辑时间（如果有）

专家版需要这些额外的细节：^{(The Expert version requires these additional details:)}

• 中央处理器速度
• 如果您有任何USB、LED设备或控制器
• 风扇数量及尺寸
• ^(Number)液冷套件或水冷套件的数量和可能的型号
• 液冷^(Liquid)或水冷泵数量
• 显卡时钟大小
• PCI 卡数

点击“计算^(Calculate)”按钮后，该网站^{(this website)}将告诉您负载瓦数^{(Load Wattage)}和推荐的 PSU 瓦数^{(Recommended PSU Wattage)}，并定义他们所说的内容。

这两种工具都很好，它们可以让您测量 PC 的总功耗。但是，第二个允许您输入监视器^(Monitor)计数和大小。否则，它们的工作方式完全相同。

How to check how much Power your Computer needs?

PSU or Power Supply Unit is one of the most important components of any computer since it distributes power to every other component that requires it to run. Do you know that you must have an up-to-the-mark Power Supply Unit to use the computer smoothly? If you provide lower power than required, your computer may not function properly. But, how do you check how much power is required for your computer? How many Watts does your computer use?

To solve that problem, here are two different PSU or SPMS buying guides or Power Supply Calculators which that will calculate your computer’s energy use which will help you buy the perfect Power Supply Unit for your computer system.

Check how much Power your Computer needs

Before opting for any of these two websites, you should know what you are about to run. In other words, you must know what are the other components of your computer. Otherwise, you may not be able to find out the best match.

1] Cooler Master Power Supply Calculator

Cooler Master is a popular brand when it comes to making an excellent Power Supply Unit. However, their website has an awesome tool that helps users find how much power their computer needs to run properly. But, as mentioned earlier, you need to enter all the component names in the respective location to get the result.

To be more specific, you need to enter the following details:

• Computer type (desktop, server, any other)
• CPU manufacturer
• Socket name
• CPU utilization
• Number of RAM and version
• Number of video cards and possible model
• Number of HDD or SSD and their possible version
• Number of optical drives and their versions
• Keyboard and mouse type (also mention if they are for gaming or not)
• PCI card
• How much time you are going to run this computer every day

After hitting the Calculate button, this website will tell you how much power your setup is about to consume and a recommended PSU wattage. After knowing this, you should look for the available PSUs in the market.

2] Outervision Power Supply Calculator

This is yet another awesome PSU buying guide that has almost same user interface as the previous one. It comes with a “Basic” version for those users who do not know much about their hardware setup. They also offer and that “Expert” version will let you enter every single detail of your machine.

The Basic version requires the following details:

• Motherboard type
• CPU count
• Ram count
• Video cards count and possible model
• Storage count and type (HDD/SSD)
• Optical drives count and type
• Monitor count and size
• Computer utilization time
• Gaming/video editing time (if any)

The Expert version requires these additional details:

• CPU speed
• If you have any USB, LED device or controllers
• Number of fan and size
• Number of liquid cooling kit or water cooling kit and possible model
• Liquid cooling or water cooling pump count
• Video card’s clock size
• PCI card count

After hitting the Calculate button, this website will tell you the Load Wattage and Recommended PSU Wattage, and they define what they say.

Both the tools are good and they let you measure your PC’s total power consumption. However, the second one lets you enter the Monitor count and size. Otherwise, they work in the very same way.
