When it comes to building your own computer, most people always think that you can skimp on quality and save money in certain areas. They believe that a computer made of mostly quality components will be a quality computer. The problem is that by putting even one low quality part into your computer only makes it as reliable and well built as that part.
When one tries to save money on a computer, usually they look at the power supply as a way to save a significant amount of money. The power supply only has to supply power to every working component in the computer. How hard can it be to supply power?
The reason why people try to save money on a power supply is obvious. Buying a cheap power supply can allow you to buy a better processor, or that motherboard that you dreamed of. Power supplies range dramatically in price and there is certainly a significant amount of money to save by choosing the cheapest power supply that you can find.
However, I advise that you purchase a quality power supply. A power supply has to do a lot more than just supply power. It has to supply extremely consistent power to very sensitive electronic devices. These devices can be destroyed by variations in voltage. Furthermore, a power supply must be able to supply this consistent power for the life of the computer.
So what should you look for in a power supply? First of all, you must select a power supply that will meet the demands of your system. Your motherboard should list a range of required wattages and your video cards may also list a minimum wattage. Do not purchase a power supply below the minimum wattage recommended. I recommend that you take the highest recommended wattage of the motherboard or video card and add 100 additional watts to that number. For example, if your motherboard requires 350 watts, purchase a power supply with at least 450 watts.
Next, you need to make sure that your power supply will have all of the connections needed for your motherboard hook up, hard drive connections, video card hook up, and so on. Most power supplies will have more than enough connection so you don’t have to really worry about this.
Finally, the fan. Your power supply will come with its own fan attached. The major thing to look at here is the noise level of the fan. Since your computer build will have other fans in it, the air flow of this fan is not critical. What is critical is that it is not unbearably loud. Choose a power supply that has a fan with a low sones or db rating. These rating indicate the sound level.
Finally, make sure that the power supply will attach to your case. Most cases are universal in terms of fitment and most power supplies are too. However, if you have a unique case, you may need a unique power. Check it out just to make sure.
Your computer almost done and the last few steps are all that’s left. Follow along as the next few articles help you complete your computer build. Building a computer is a rewarding and enjoyable experience.
