Computer Components

Buying guide

We all know that computers need several high-tech parts to function, like a processor, a hard drive and a motherboard. What some people overlook is that some of the more simple components of a computer are just as important. Computers need sturdy computer cases to protect all the high-tech parts inside, and they need cooling systems to keep the inner-workings from overheating. After all, what's the point of having expensive inner-workings if they aren't kept in good working order? Take the time to find the right computer components for your machine.

All computers need power in order to function. Power supplies are the part of your computer that convert the AC power from your home into the DC power your computer needs. Although power supplies are generally quite cheap (some can be purchased for as little as $10), they are vital to the performance of a computer. Poor-quality power supplies aren't always able to provide your computer with enough power, which is like slowly starving your computer. You may not realize that anything's wrong, but before you know it, your motherboard is fried. Always make sure to get a quality power supply. In fact, it's often a good to upgrade your power supply if you have purchased a computer made by a big company like Dell or Compaq. Sometimes these mass-manufacturers try to save money by using cheap power supplies.

In a way, surge protectors perform the opposite job of power supplies. They ensure that your computer doesn't receive too much power, which can be equally damaging to the parts inside. Power bars that offer surge protection as a feature can be purchased at any hardware store.

If you use your computer a lot (especially for gaming, which can cause your parts to overclock), you will want to make sure that you have an excellent cooling system installed. Sometimes, fans aren't enough to keep your computer from overheating and you may need to consider a liquid cooling system, also known as a water cooling system. Not only are liquid cooling systems more efficient than fans at cooling down computers, but they are also much quieter. If you're the kind of person who sits at the computer for hours on end with several applications open, a liquid cooling system is probably a wise investment.
