Power to the computer is the most critical component, and this can be one of the most overlooked. It goes without saying that it will always be there and working properly. The top of the line processor and ultra-strong video card does nothing if the system does not receive the abundant, stable energy it requires. It is extremely important that the power supply and control components delivered to your computer are quality components, and this brief overview examines some remarkable areas.
The computer's power supplies take the high (110V or 220V) DC power from an electrical outlet and convert it to the various lower AC voltages needed to operate the system. Typical voltages inside the computer are 3.3 V, 5V, and 12V, where the 3.3V and 5V lines are generally used for circuits, while the 12V line is used to run hard drives, optical drives and cooling fans. .
Power supplies are sold based on their performance based on performance. Choosing the right power supply means not only that it provides enough power for all components connected to the system, but also that that is physically fit, has enough connections for typical drives and fans, and if necessary, it also has special connections for Serial ATA drives and modern video cards.
Choosing the power supply that has enough power cannot be a big problem as it requires more energy than you need, never a bad thing. Just because the power supply is rated at 400 W, or maybe 600W, does not aggravate drawing at a particular time. This only indicates the total performance available for different lines within the computer. For those who are interested in minimum performance requirements, this power-performance calculator is a convenient reference. In addition to controlling the full power of the power supply, we also recommend a strong performance evaluation of the 3.3V, 5V, and 12V lines, as power supplies with the same performance divide power into different lines.
Power supplies have a few different physical sizes, but the most common are standard ATX and micro ATX (mATX) formatted cases. A typical ATX power supply, such as the Echo-Star 680W, has a size of 3.25 "x 6" x 5.5 and has two cooling fans that not only cool the power supply but also extract hot air. The mATX power supply, such as the A-Power 320W unit, has a 2.5 "x 5" x 4 measurement, and because of its smaller size there is only one cooling fan. MATX cases are generally much smaller than ATX cases and therefore have less power, usually with lower power values and fewer connectors.
It is also worth considering the power supply connectors. Most power supplies include an electric octopus that hangs from the back surface and make sure that the tangled bundle is all the necessary connectors somewhere. The power supply must have at least as many connections as the drives, cooling fans, and other cases found in the case. Until recently, power supplies had a fixed number of connections, and if you needed more, you had to use the separators to distribute performance to all components. Now there are modular power supplies like the Ultra X-Connect 500W unit that eliminates this "electric octopus" and allows the end user to connect only the necessary cables. The flexibility of the modular power supply design is not only tailored to your needs, but also enables simple and orderly installation, as there are no additional wires hanging inside the house.
Choosing a high quality power supply can advance, but you can save money along the way. Many manufacturers now offer power supplies that consume less power thanks to high-quality internal components, advanced designs, and active power factor correction. These units are now capable of delivering the same performance to computer components, but with less power, they get less power from the electrical outlet.
The purpose of surge protection is to protect your electronics from short voltage increases caused by lighting, rolling power cuts and heavy electrical drawings. The surge protector reacts to direct the extra electricity to the ground to protect expensive computer equipment from damage. Overvoltage means all three nanoseconds or longer, so the surge protector has to react quickly. Most overvoltage protection includes a fuse (or circuit breaker), and if the overvoltage is too high to be handled without interference, the fuse blows. Though the fuse can be destroyed, there is little loss than it is saved.
Surge protectors are in all shapes and styles. Some basic models can be found in the local dollar store, but not more than a deal connected to a circuit breaker. There is no serious protection, but many want more protection than protection.
The heavier surge protectors are likely to pay a little more than a dollar, but they provide some peace of mind to really protect the device. In addition to electrical surge protection, some devices also include additional features such as conditioning to filter out line noise and ports to protect other lines, such as cable television, phone and network.
Fellowes Smart Surge Power Strip protects up to 10 devices from overvoltages, and line and port protection to protect your phone line. The extremely attractive feature of such a surge protector is that the connector 4 is designed to accept large network adapters. Surge protectors who have not been so user-friendly are still hopeful in the form of Power Strip Saver cables. Basically, only 7 inches of extension, these batteries can be very useful when connecting multiple AC adapters to a more conventional surge protector.
Uninterruptible Power Supplies
Many are familiar with UPSs to know that they can keep and operate the computer during a power outage, but they don't know what else to do. Most uninterruptible power supplies provide protection against voltage surges and interruptions (when the voltage drops below the normal value) and protects against the shifts in the frequency of electricity.
Uninterruptible power supplies are of two types, standby and continuous, although standby versions are much more common and cheaper. The standby uninterruptible power supply allows the connected devices to operate from the normal electrical connection while the power failure is detected and then quickly (in milliseconds) switches to UPS battery backup. The continuous uninterruptible power supply always has the devices connected to it to charge the battery while the batteries are charged with a normal electrical connection.
Uninterruptible power supplies are sold according to their capacity using VA (voltage multiplied by current). This assumes that the devices connected to the UPS can raise the maximum voltage to a specific voltage. Usually, the run time after power failure is given to the UPS based on the total load placed on the device.
The choice of uninterruptible power supply should be based on the intended use … A smaller unit, such as the Fenton 600VA, would be enough to power a typical desktop computer, monitor and small peripherals such as printers and lights. for a total load of 15-23 minutes. If more systems need to be fed, or there are plans for future expansion that increase energy demand, a larger unit such as Tripp Lite 1500VA may be more appropriate. The first two units should be configured to be close to power supply devices, although behind the desk on the floor, but if you want to add a UPS to a server, there are rack solutions like the Opti-UPS 1100VA.
Regardless of the application, the size of the UPS seems to be overwhelming. One manufacturer, APC, has created a convenient UPS selector application that makes some guesses about selecting the appropriate UPS for that application.
The computer system is just as strong as its weakest attribute, and often this difference falls on the power supply and related components. By choosing a high-quality power supply, surge protector, and possibly a UPS, you can make sure that they have an extremely strong and stable performance to operate their systems and on the road when upgrades can increase the demand for their systems.
