Remove A Power Supply 卸下電源(P.41)
Learning objective 學習目標
• Disassemble and reassemble computers in the most common case designs.
在最常見的案例設計中，拆卸並重新組裝計算機。
• Recommend and install an appropriate power supply given specific hardware to be powered.
根據要供電的特定硬件，建議並安裝適當的電源。
• Test power supplies to ascertain proper functioning.
測試電源以確定功能正常。
To remove the power supply, first you must power down the computer. Next, you want to verify the power switch is in the off position, and disconnect the power cord from the wall and from the machine. You can then open the case by removing the screens, and then disconnect all power supply cables from all the devices in the computer. Next, you will remove all the screws holding the PSU in place and lift or slide out the power supply from the workstation.

Replace A Power Supply 更換電源
To replace a PSU, you would need to verify the proper wattage for the new power supply and slide the power supply into the case. You then need to screw the power supply into place and connect all the power supply cables to the various internal components. Next, you should check the voltage setting and make sure it is set to 110 VAC for North America or 230 VAC for European/Asian countries. Connect your power cord to the power supply and turn on the computer. If the computer works properly, you can then close the case and secure the enclosure with screws.
要更換PSU，您需要驗證新電源的合適功率，並將電源滑入機箱。 然後，您需要將電源固定到位，並將所有電源電纜連接到各種內部組件。 接下來，您應該檢查電壓設置，並確保將其設置為北美的110 VAC或歐洲/亞洲國家的230 VAC。 將電源線連接到電源，然後打開計算機。 如果計算機正常運行，則可以合上機箱並用螺釘固定機箱。
Test a Power Supply 測試電源
In order to test a PSU, you can use either a multimeter or a power supply tester. While a multimeter would work, you must be able to know the exact pinout for each type of connector and the amount of voltage to expect from each pin. Instead, it is much simpler to buy one of many different computer power supply testers on the market today. Small LEDs light up to let you know if the power feeds are working correctly. The motherboard power tester also beeps to let you know it is receiving the correct amount of power. This device is a must for anyone who wants to be able to test power supplies quickly and easily. To use it, simply hook up the motherboard power connector (20+4 connector) to the right side of the tester. Next, hook up the power connector for the device (SATA, Molex, Berg, etc.) to the left hand side of the tester. The lights will show up green if you are receiving the proper voltages (3, 5, 12 VDC).
為了測試PSU，可以使用萬用表或電源測試儀。 儘管萬用表可以工作，但您必須能夠知道每種連接器的確切引腳排列以及每個引腳的預期電壓量。 相反，購買當今市場上許多不同的計算機電源測試儀之一要簡單得多。 小型LED會亮起，以告知電源是否正常工作。 主板電源測試儀還會發出嗶嗶聲，以通知您它正在接收正確數量的電源。 對於希望能夠快速輕鬆地測試電源的任何人來說，此設備都是必需的。 要使用它，只需將主板電源連接器（20 + 4連接器）連接到測試儀的右側即可。 接下來，將設備（SATA，Molex，Berg等）的電源連接器連接到測試儀的左側。 如果您接受適當的電壓（3、5、12 VDC），則指示燈將呈綠色亮起。
