Factors to Consider When Purchasing Desktop Accessories for Older Computers

Buying new desktop accessories is a good way to enhance the performance of an older computer. The right accessories enable consumers to gain richer multimedia experiences from their machines. Many of those interested in buying desktop accessories may be surprised to learn that many of the newest accessories still work with computers that they thought they may have had to replace. This is not always the case though, so it is important that consumers consider a few important factors when purchasing desktop accessories for older computers.

First, consumers must be aware of the factors that determine whether or not desktop accessories are compatible with older computers. Second, consumers must understand what certain common accessories require of the computers they are intended to work with. eBay is a good source from which to buy desktop accessories, so consumers should be familiar with the basic points of buying on the site. Combining relevant knowledge of the factors influencing how desktop accessories work with older computers, with familiarity with buying on eBay helps consumers enhance their machines.

Factors that Determine Compatibility of Desktop Accessories with Older Computers

No matter how consumers choose to modify or enhance their older desktops, there are a number of important factors that determine the compatibility of the desktop accessories they would like to purchase. Consumers should consider the interfaces, computing and graphics power, and cooling capability of their older computers when purchasing accessories. Doing so reduces the risk of buying accessories that do not work with a computer.


The interfaces that a computer has it govern whether or not accessories can work with the computer. With some more basic accessories, the interface is the sole factor that determines this. Many newer accessories use a USB interface, so it is important that an older computer has USB ports on it.

The video port is also important for connecting a monitor, so it is important to either choose a compatible monitor or purchase a conversion device. It is relatively simple to determine if an accessory and a computer have interface compatibility, so this is a good place to start when determining if an accessory can work with an older desktop.

Computing and Graphics Power

Some of the more advanced desktop accessories require certain levels of computing and graphics power. Consumers should therefore check the processors, RAM, and video cards on their older computers to be sure that certain accessories can work with the computer.


Any older desktop should have a sufficiently powerful processor to keep up with the demands that accessories and related software put on it. The processor is the computer's brain, and enhanced functionality requires a more powerful brain. The more cores a processor has, the more powerful it is likely to be.


An older desktop computer should have enough random access memory (RAM) to run programmes associated with new accessories. The RAM temporarily stores data while the processor executes commands. It essentially creates a data queue for the processor. The bigger the queue is, the quicker the user can move between programmes and commands because the computer allows the user to move on to another function once the data from the last function is stored in the RAM.

Graphics Card

A good graphics card is necessary for many video-based accessories. Consumers cannot expect to realise the full potential of these accessories if the video cards in their older computers are not up to task. One good way to test this is to watch streaming videos on the Internet in 1080p. If the computer performs well in this function, it should be able to handle newer video accessories.

Cooling Capability

New accessories can put added stress on a processor and a graphics card. Consumers should make sure that their older desktops are capable of cooling the heat that accessories can produce on these integral parts. A good fan and heatsink comprise a desktop computer's cooling system, and both of these are replaceable if the system struggles to sufficiently cool the computer.

Desktop Accessories for Older Computers

In addition to the computer's components, the desktop accessories themselves determine if they are compatible with an older computer. By being familiar with how a handful of key desktop accessories work with computers, consumers can judge whether or not accessories they are interested in are compatible with their own machines.

Practical Use Accessories

Keyboards, mice, monitors, and printers are among the more common desktop accessories that consumers buy for their computers. A computer's interface is an important compatibility determinant for all of these, and the graphics card can matter too.


Keyboards are relatively basic accessories and require only the right connection to work with an older computer. Many currently manufactured keyboards employ a USB connection, so they should work with older computers that have a USB port. It is also possible to use a wireless keyboard with an older computer since the wireless connection is usually established via a USB dongle that goes into the computer's USB port.


Mice are also relatively simple. As is the case with keyboards, these accessories usually only require the right connection ports on an older computer. Many current mice and use a USB connection, and wireless mice employ a USB dongle.


The high-definition revolution swept up computer monitors as it did televisions. Many consumers have caught the high-definition wave and upgraded their old CRT monitors to LCD ones. Before upgrading to one of these monitors, consumers should make sure that their old computers have matching outputs.

Consumers should also realise that they can only get high-definition graphics on their monitors if their old computer's graphics cards are up to the task. A good graphics card can produce the high frame rates and deep hues that are key features of the high-definition viewing experience.


A printer is another common accessory that consumers purchase for their computers. Once again, having the right connections is important to ensuring that a new printer works with an older computer. Many current printers use USB connections. The computer's processor and RAM should also be capable of running any advanced photo or graphics software that consumers intend to print from.

Enhanced Use Accessories

Many consumers purchase certain desktop accessories to enhance their use of their computers. Accessories such as webcams, microphones, speakers, and TV tuners and video capture devices make computers more interactive and improve their multimedia capabilities. A good processor and the right connections are necessary to use these accessories with older computers.


A webcam captures video and either streams it live over an Internet connection or saves it to the computer's hard disk drive. High-quality video requires a high frame rate and sharp resolution. If consumers want webcams that produce clear videos, their computers must have a processor capable of delivering these demands. A slower processor results in slower video, degrading its quality.


Microphones enable users to stream and record sound, and a good microphone does both without distorting sound. These accessories plug into a computer's sound card, so the card must have a matching port.


Good speakers improve a computer's multimedia capabilities. Whether watching a movie, listening to music, or chatting with a friend, the right speakers reproduce sound powerfully and clearly. A good sound card in an older computer helps consumers get the most out of their new speakers. They should also make sure that the connections between their computers and their new speakers match. Many newer speakers use a USB connection, but it is also possible to find ones that plug into the 3.5 mm mini-jack that many older computers have.

TV Tuners and Video Capture Devices

TV tuners and video capture devices enable consumers to watch and record television on their computers. Some of these devices connect to a USB port, but higher-end versions are generally cards that consumers install into their desktop towers. The former obviously require a USB port on an older computer, while the latter need an unused PCI slot on the computer's motherboard. If consumers plan to purchase TV tuners and video capture devices in the card format, they should make sure that the card has the same type of PCI connection as the motherboard on the computer.

How to Buy Desktop Accessories on eBay

It is possible to buy desktop accessories from local and online computer goods retailers. You can also find all of the desktop accessories you need for your older computer on eBay. The site has an extensive selection of many different types of accessories. It is easy to search for the ones you want, and you can save money on shipping by choosing to buy from local sellers.

Searching for Desktop Accessories

You can conduct a search from any eBay page that has the search bar. Enter the term for the accessory you want, such as "webcam", into the search bar. You can then choose the appropriate series of categories to ensure that the results are related to your search. Lastly, select the features that you want for the accessory and browse the listings to find ones that appeal to you.

Finding Local Sellers

Buying from local sellers is a great way to save money when you shop on eBay because it often reduces the cost of shipping. You can find local sellers by specifying the distance from your postcode within which sellers should be located. eBay then filters the results to leave a listing of sellers near you.


The right desktop accessories can help consumers get more out of their older computers. Many consumers may think that they have to replace their machines in order to use the accessories that they want. However, they can save significant amounts of money by taking extra steps to see how they can use these accessories with their older computers. Understanding compatibility and functionality between older computers and newer accessories helps consumers realise that they can use many accessories on their computers that they previously thought they could not.

Consumers should first see if their older computers have the right interfaces, enough computing and graphics power, and the capability to properly cool themselves for using new desktop accessories. Consumers should also understand how common desktop accessories work with computers. By understanding both aspects of using desktop accessories on older computers, consumers can successfully purchase the accessories they need from a source such as eBay.
