Introduction
In the realm of computer systems, one crucial component reigns supreme: the power supply. Acting as the life force of your device, its primary function is to convert the incoming AC power from a wall outlet into the essential DC power that fuels the components within your computer. The importance of having an efficient and high-quality power supply cannot be overstated, as it not only ensures stable power delivery but also significantly contributes to the longevity and reliability of your entire computer system. In this comprehensive guide, we will delve into the various types of computer power supplies, shed light on the key factors to consider when selecting one, and emphasize their paramount importance.
Types of Computer Power Supplies
When it comes to computer power supplies, two primary types dominate the market: standard ATX power supplies and modular power supplies. The standard ATX power supply, often referred to as the traditional power supply, is equipped with fixed cables for power delivery. This type of power supply is generally less expensive and suits basic computer systems admirably. On the other hand, modular power supplies offer a distinctive advantage with their detachable cables. This feature not only simplifies cable management but also has the potential to enhance airflow within the computer case, promoting efficient cooling.
Wattage and Efficiency
A critical factor to consider when selecting a power supply is its wattage rating. The wattage rating determines the amount of power the power supply can deliver to the components inside your computer. Power-hungry components such as high-end graphics cards or processors demand a higher wattage power supply. However, it is crucial to strike the right balance, as a power supply with an excessively high wattage rating can be wasteful and unnecessary, leading to unnecessary expenses.
Efficiency also plays a significant role in choosing a power supply. The efficiency rating measures the percentage of AC power input that gets converted into DC power output. A higher efficiency rating indicates that less power is wasted as heat, resulting in reduced operating costs and an extended lifespan for the power supply. Therefore, opting for a power supply with a high efficiency rating is a wise decision for both your wallet and the overall performance of your system.
Connectors and Cable Management
The power supply must possess the appropriate connectors to power all the components inside your computer effectively. Common connectors include the 24-pin motherboard connector, 4/8-pin CPU power connector, SATA power connectors, and PCIe power connectors for graphics cards. Before making your final power supply choice, it is essential to thoroughly review the power requirements of each component to ensure seamless compatibility and proper functioning.
Cable management is another vital consideration in maximizing the performance of your computer system. Effective cable management not only improves airflow within the computer case but also minimizes clutter, resulting in an organized and visually appealing setup. A modular power supply can be particularly advantageous in this regard, as it allows for easier and more efficient cable management by eliminating unnecessary cables.
Brand and Quality
Selecting a reputable brand and investing in a high-quality power supply are paramount to the reliability and longevity of your computer system. A good power supply not only guarantees stable power delivery to your components but also provides protection against power surges, mitigating the risk of hardware failure. Several renowned brands have made a name for themselves in the power supply market, including Corsair, EVGA, Seasonic, and Thermaltake. Opting for a power supply from these trusted manufacturers will significantly contribute to the overall performance and durability of your computer system.
Conclusion
To sum it all up, a computer power supply stands as an indispensable component in any computer system. When embarking on the quest to select the perfect power supply, it is crucial to consider factors such as wattage rating, efficiency, connectors, and cable management. By meticulously assessing these factors and making informed decisions, you can ensure that your computer system is equipped with a stable and efficient power supply that impeccably meets its unique needs. Remember, investing in a high-quality power supply from a reputable brand is a small price to pay for the reliability and longevity of your computer system. So, empower your computer with the right power supply and let it thrive!

A digital multimeter has many different settings to help diagnose electrical problems.
The power supply on a computer transforms the alternating current from the wall outlet into a direct current flow that the computer's components can use. Testing the DC voltage output of the power supply using a digital multimeter can help you isolate any potential issues and determine if you have a bad power supply. Always use the probes to touch wires and terminals -- never use your fingers. If you can't hold the wires or terminals with the probes, use a stand or binder clip to secure them so you don't have to hold them with your hand.
1.
Test the outlet and surge protector into which the power supply has been plugged. Power off the computer, unplug it from the surge protector, and then unplug the surge protector from the wall outlet.
2.
Set your digital multimeter to measure AC voltage. The AC symbol is a "V" with a "~" near it. Set it to the range of 200 V. Insert one probe into the left side of the outlet and the other into the right. Since the current is alternating, the probe color doesn't matter. You should see a reading of between 110 and 120 volts.
3.
Plug the surge protector into the outlet, and then test the surge protector. The reading should still be between 110 and 120 volts.
4.
Set your multimeter to measure resistance; the symbol is "Ω." If there is a symbol on your dial that looks like an arrow pointing to sound waves, use that one. The multimeter makes a sound if there is continuity along a wire. Remove the cord connected to the power supply on the back of the computer. Touch one of the plug terminals with one of the DMM probes. Put the other probe into the female end of the cord. If none of the holes produce a tone on your multimeter, then the cord is bad and needs to be replaced. If you have continuity for each of the three wires in the power supply cable, then there is an issue with the power supply.
5.
Remove your computer's case, and then locate the place where the power supply attaches to the motherboard. The ATX style power supply won't operate unless it is connected to the motherboard, so you must insert the probes into the back side of the connector to make contact with the wires.
6.
Note the orientation of the clip that secures the connector to the motherboard; the clip is between pins 15 and 16. The pins on that side are 11 through 20, and the pins on the opposite side are 1 through 10. Power is carried through pins 1, 2, 4, 6, 9, 10, 11, 19 and 20. Use a pin diagram to identify the different testing locations (link in Resources).
7.
Set the multimeter to read DC voltage. The symbol is "V" and a straight line over a broken line. Set the range to 20 volts.
8.
Insert the black probe into the back of the connector with any black wire. Insert the red probe into the back of pin 10. Power on the computer. The multimeter should read between 11 and 12 volts. If it's too high or too low, the power supply is failing and needs to be replaced. Test pin 12 as well.
9.
Test pins 4, 8, 9, 19 and 20 for 5 volts. If the voltage is too high or low, the power supply is failing.
10.
Test pins 1, 2 and 11 for 3.3 volts.
Warning
Don't attempt to salvage or repair a failing power supply, as doing so may damage your computer.

If your PC is refusing to work with another piece of hardware, or running into problems when booting up, you may need to update or change your BIOS to correct the issue. Here’s a step-by-step guide on how to make changes to get your computer working.
Related: How to reinstall Windows 10
What is the BIOS?
The BIOS (or Basic Input Output System) is the very first thing your computer reads when you switch it on. It’s located on your PC’s motherboard, away from the rest of the system disks, so it won’t be corrupted if your hard drive fails.
This firmware’s primary function is to get your computer up and running, by initialising the hardware and then loading up the operating system (OS). The BIOS checks your processor and memory is present and correct, while also detecting which peripherals (keyboard, mouse and so on) are attached to your PC. Following that, it checks to see if you’ve inserted a boot disc. If none is found, it loads the OS into memory and gets things started up.

Should I make changes to the BIOS?
Tinkering with your BIOS can help to rectify any severe problems that your PC is experiencing, if you can’t actually boot into Windows to make changes there. As long as you know what you’re doing, of course.
Likewise, updating the BIOS with the latest version can allow your computer to play nice with new peripherals and hardware, which previously weren’t supported.
However, and we can’t stress strongly enough, playing around inside of the BIOS settings without the proper knowledge can lead to serious anguish. As in, your computer may be completely borked if you improperly change any of the settings. So if you’re having issues with your PC booting up or not recognising new peripherals and you’re not experienced in this area, you should consult a technician instead of throwing yourself blindly into the abyss.

What should I do before making changes to the BIOS?
If you’re working with a laptop, then make sure it’s plugged in and the battery is at least half charged. If the power suddenly cuts partway through the update process, then things could get very ugly indeed.
Before starting you should also check which BIOS version you’re using, so you can find out if a newer version is available from your motherboard’s manufacturer.
How do I check which BIOS version I’m using?
The easiest way to do this is using the Windows Command Prompt. In the search box at the bottom left corner of your Windows desktop (beside the Windows start button), type in ‘cmd’ and press enter. A command window will pop into existence.
In here, type the following: Wmic bios get biosversion
Some text will pop up, revealing the current version number.
Alternatively, you can open a command window in the same way and type in: DXDiag
A DirectX Diagnostic window will appear on-screen. Beside the ‘BIOS’ entry in system information, your current version will be listed.
Once you know your BIOS version, you can then check on your manufacturer’s website to see if a newer version can be downloaded.
How do I update my computer’s BIOS?
To download the latest version, you’ll need to head to your motherboard manufacturer’s website (on a different computer if your own refuses to boot, of course). If you’re not sure of the make and model of the motherboard stashed inside of your PC, and your computer manuals have vanished into the ether, then you can always use a tool such as CPU-Z – again, assuming your PC actually functions.
On the manufacturer’s website, head to the downloads or support section and search for your model number. You should see the option to grab the latest BIOS edition, which will often download as an executable Windows program. Once this program has downloaded, you can simply run it from within Windows. This will wipe the BIOS and replace it with the latest info. Again, take every precaution to avoid losing power, as this could critically harm your computer. Also, note that you may need to disable your antivirus and security applications if the program fails, before running it again.
Alternatively, your manufacturer may provide a program to create a bootable flash drive. Download this from the website as above, but this time you’ll need to provide a USB stick or other external drive with enough space to hold the necessary files. Make sure the drive doesn’t have anything important on it, because it may be wiped in the process.
Connect it to your PC and run the program you just downloaded, and the files will be copied onto the external drive.
Now you’ll have to reboot your computer with the external drive still connected. Press F12 when the PC begins to load and you’ll be asked for a source. Select the external drive and then simply follow the on-screen instructions to update the BIOS.
How do I make changes to my BIOS?
If you wish to make direct changes to your BIOS, for instance to change the boot up checking sequence to load an OS from disc instead of the computer’s main drive, then you’ll need to go into the BIOS and fiddle with it directly. You can do this as your computer first boots up.
As soon as you hit the power button, you’ll see some text flash up on your monitor. One of these lines of text will tell you what key to press in order to enter the BIOS. It’s usually the Delete key, but this may differ depending on your motherboard.
A menu will appear offering a variety of options and settings. Remember, only make changes if you’re absolutely confident that you won’t cripple the computer.
