Inside your computer is a component that is the lifeblood of your hardware system. It is responsible for your motherboard, your hard drives, your CD and DVD drives, and a half-dozen other possible components. For many people, the only part they see of this important component – the power supply – is the rear where they plug in the power cord from the wall.
The power supplies job seems simple: to convert alternating current (A/C) to direct current (D/C) which, like most electronic devices, is what your computer uses. Inside the computer case, various wires and plugs are attached coming out of the power supply.
These are attached to the different components inside the computer. Some higher-end power supplies from OCZ, CoolMax, and Ultra allow you to only attach the wires and plugs you need. This can create less clutter inside the case and help to improve airflow which keeps your computer running cooler.
Mini Itx Power Supply and Apevia Power Supply- Megatech Distributor include power supplies that are cheaply made and have very minimal power capabilities. A power supply is measured primarily in terms of watts. Finding out how many watts a power supply can generate is the first way to determine if your computer system is risking being underpowered.
Even today, some systems are still shipping with 150-watt power supplies. This is hardly acceptable. A basic system should have, at the least, 350 watts of power capability. Many systems have 500 watts or more of power available, and some high-end gaming systems are being fitted with 1000 watt power supplies.
The number of components that might be running at once determines how much power you need. Your motherboard consumes more power when you are running processor-intensive tasks such as games, 3-D modeling or graphics, and multimedia applications. You might have your hard drive and your DVD player going at the same time.
When buying a new power supply, take the time to determine your long-range plans for your computer system. Don't buy just enough power for the moment. Buy enough for future upgrades as well. You can't really go wrong with too much power. But don't buy a power supply that far exceeds your realistic expectations; you'll just be wasting electricity.
