Hey Everything in Portland Computer Repair Land,
When you see a computer advertised, it will often say it has an intel processor, or crucial RAM, but what about the internal components that they don’t advertise?
There are two very important parts in every computer that nobody ever advertises on the outside. One is the motherboard. The motherboard is the most expensive and most important part of your computer. It is the computer’s spinal column, responsible for transmitting all of the signals between the various components inside the computer. When you save a document, the command goes from the keyboard, to the motherboard, and from the motherboard to the processor. The processor processes the command, then sends it back to the motherboard which sends it over to the hard drive.
And yet, nobody ever advertises the motherboard! And believe me, there are substantial qualitative differences between motherboards. For example, consider the question of expandability. Different motherboards have different options for how they can be expanded to make your computer run faster, and live longer down the line. For example, ask how many RAM slots your motherboard contains. The number of available RAM slots will directly affect your ability to upgrade your computer down the line, and the cost of the upgrades.
A computer with 2 RAM slots will be much more expensive to upgrade than a computer with 4 RAM slots, a computer with two upgrade slots for extra cards (for example, to add wireless capability to your computer, or to add firewire support) has more room to upgrade than many new computers that come with zero expansion slots.
Then, beyond speed and upgrade cost, there is raw quality to consider. If your motherboard says, “Foxconn” on it, it will fail in 12-18 months, because Foxconn builds the cheapest piece of crap boards in the world (and supplies every motherboard for the Gateway corporation). If your motherboard says “MSI” on it, don’t expect more than 24 months out of it, because you probably won’t get it. And when a motherboard fails, you’ll be out of pocket serious cash. The average motherboard replacement, parts and labor, costs $300-400!
Finally, lets consider the power supply, a part few people know exists. You see, your computer can’t use the power that comes out of the wall, so inside the computer there is a box that converts the power from the wall into power your computer can actually use. This box is called the power supply, and its the single most important thing you will buy.
The power supply matters most because of the damage it can do if/when it fails. Often times when a power supply fails, it will surge with power, or provide insufficient power before it stops working. When it surges, it frequently overpowers and destroys many valuable components inside your computer. A failing power supply can take out your hard drive, motherboard, and processor, and by itself become the cause of buying a new computer. This means, for want of a high quality power supply (price of $60 or so) you can lose all your data, and almost everything else in your computer.
Finally, wattage matters a great deal. Power supplies are rated in watts, and if your computer draws more than 80% of the wattage rating of the supply, the odds of failure skyrocket.
So, the next time you go to the store, ask a few questions -
1) Who manufacturers my motherboard, and what kind of warranty do they provide beyond the included 1 year warranty for the computer?
2) How much expansion is available on my motherboard so I can grow with my computer in the future?
3) Who manufacturers my power supply, and what kind of warranty do they provide beyond the included 1 year warranty for the computer?
4) What is the maximum load of my power supply as a percentage? How much wattage does it produce?
5) Does my power supply have extra wattage available for upgrades in the future that may draw additional power?
If your sales rep can’t answer those questions, don’t buy it.
Thanks,
-Zac
