Power In Addition To Your PC

The power coming into a computer can be the most critical component, in addition to This particular may be one of the most overlooked. This particular can be just taken for granted which This particular will always be there in addition to working properly. A top of the line processor in addition to ultra powerful video card do nothing if a system does not receive the ample, stable power This particular demands. Having quality components providing in addition to regulating the power supplied to a computer can be critical, in addition to This particular brief overview looks at a few areas worth consideration.

Power Supplies

Power In Addition To Your PC

Computer power supplies take the high (110V or 220V) DC voltages via an electrical outlet in addition to convert This particular to the various lower AC voltages required for a system to operate. The typical voltages required inside a computer are 3.3V, 5V, in addition to 12V, where the 3.3V in addition to 5V lines are generally used to power circuitry, in addition to the 12V line provides power to run items such as hard drives, optical drives, in addition to cooling fans.

Power supplies are sold in terms of their total power output, in terms of wattage. Choosing the correct power supply means not only finding one which will provide enough power for all of the components connected to the system, nevertheless also one which can be the correct size physically, has enough connections for typical drives in addition to fans, in addition to if necessary, which also has special connections for things such as Serial ATA drives in addition to modern video cards.

Choosing a power supply with enough power shouldn’t be much of a problem, as having more power than you need can be never a bad thing. Just because a power supply can be rated for 400W, or perhaps 600W, does not imply which This particular can be drawing which at any given time. This particular just indicates the total power available to the various lines inside the computer. For those interested in getting a not bad idea of their minimum power requirements, This particular Power Wattage Calculator can be a convenient reference. In addition to checking out the total wattage of a power supply, looking for strong amperage ratings on the 3.3V, 5V, in addition to 12V lines can be also recommended, as power supplies with identical total power ratings may distribute the power to the various lines in different quantities.

Power supplies come in a few different physical sizes, nevertheless the most common are designed to fit the standard ATX in addition to micro ATX (mATX) form factor cases. A typical ATX power supply, such as This particular Echo-Star 680W unit, measures 3.25″ x 6″ x 5.5″ in addition to features two cooling fans to not only cool the power supply, nevertheless to also help draw hot air out of the computer. A typical mATX power supply, such as This particular A-Power 320W unit, measures 2.5″ x 5″ x 4″ in addition to due to the smaller size features just one cooling fan. mATX cases are generally much smaller than ATX cases, in addition to therefore have smaller power supplies, with generally lower power ratings, in addition to fewer connectors.

The connectors on a power supply also deserve consideration. Most power supplies come with what looks to be an electric octopus of wires hanging off the back surface, in addition to you need to make sure which somewhere in which tangled bundle are all of the connectors you need. The power supply should at least have as many connections as the number of drives, cooling fans, in addition to some other items found within the case. Up until recently power supplies had a fixed number of connections, in addition to if you needed more, you needed to use splitters to distribute the power to all the components. Modular power supplies, such as the Ultra X-Connect 500W unit, are right now available which eliminate which “electric octopus” all together, in addition to allow the end user to connect just the cables they need. The flexibility of a modular power supply design not only lets you customize the connections to your needs, This particular also makes for a simple in addition to tidy installation, since there are no extra wires dangling inside the case.

The selection of a high quality power supply may cost more money up front, nevertheless down the road This particular could wind up saving money. Many manufacturers right now offer power supplies which consume less energy thanks to high quality internal components, advanced designs, in addition to active power factor correction. These units are right now able to provide the same power to the components in a computer, nevertheless due to increased efficiency, draw less power via the electrical outlet.

Surge Protectors

Surge protectors are intended to protect your electronics via a brief increase in voltage caused by such things as lightning, rolling blackouts, in addition to heavy drawing electrical equipment. A surge protector reacts to divert the extra electricity to ground, thereby protects your expensive computer equipment via damage. A surge can be any increase lasting three nanoseconds or longer, so a surge protector needs to react quickly. Most surge protectors also include a fuse (or breaker), in addition to if the surge can be too great to be handled without interruption, the fuse will blow. Although the fuse may be destroyed, This particular’s a modest loss compared to what This particular may have saved.

Surge protectors come in all shapes in addition to styles. Some basic versions can even be found at your local dollar store, nevertheless offer no more than a few outlets connected to a breaker. No serious protection can be obtained, nevertheless many people just want more outlets, not protection.

More serious surge protectors will probably cost a bit more than a dollar, nevertheless will offer some peace of mind which your equipment can be actually being protected. In addition to protecting via electrical surges, some devices include extra features such as conditioning to filter out line noise in addition to ports to protect some other lines such as cable television, telephone, in addition to networking.

The Fellowes Smart Surge Power Strip protects up to 10 devices via surges, as well as offering line conditioning in addition to ports to protect your phone line. A highly appealing feature of such a surge protector can be which 4 of the ports are designed to accept bulky AC adaptors. For those with surge protectors which weren’t designed to be This particular user friendly, there can be still expect within the form of Power Strip Saver Cables. Basically just 7 inch long extension cords, these items can come in very handy when trying to connect multiple AC adaptors to a more traditional surge protector.

Uninterruptible Power Supplies

Many people familiar with Uninterruptible power supplies (UPS) know which they can keep a computer up in addition to running during a total power failure, nevertheless don’t know what else they do. Most UPSes will also provide protection via voltage surges in addition to sags (when the voltage drops below normal), as well as protection via the possibility of a shift within the electricity’s frequency.

UPSes come in two varieties, standby in addition to continuous, although standby versions are far more common in addition to less expensive. A standby UPS allows the devices connected to This particular to run via the normal electrical connection until a loss of power can be detected, at which point This particular quickly (in a matter of milliseconds) switches to the battery backup of the UPS. A continuous UPS always has the devices connected to This particular running off of battery power, while the batteries are recharged by the normal electrical connection.

UPSes are sold in terms of their capacity, in terms of VA (voltage multiplied by amperage). This particular implies which devices connected to the UPS can draw a maximum of so much amperage at a specific voltage. A run time after a power failure can be also generally specified for a UPS based on a full load being placed on the device.

Selecting a UPS needs to be based on the intended use… A smaller unit, such as the Fenton 600VA, would likely be adequate for powering a typical desktop computer, monitor, in addition to smaller peripherals such as a printer in addition to lighting for what they rate as 15-23 minutes at full load. If multiple systems need to be powered, or perhaps there are plans for future expansion which will add to the power demands, a larger unit such as the Tripp Lite 1500VA may be more appropriate. The first two units are intended to be set in close proximity to the devices to be powered, perhaps on the floor behind a desk, nevertheless if you are seeking to add a UPS to a server, there are also rackmount solutions such as the Opti-UPS 1100VA.

No matter the application, sizing a UPS may seem overwhelming. One some sort of, APC, has created a handy UPS Selector Application which will take some of the guess work out of choosing the right UPS for any particular application.

Final Words

A computer system can be only as strong as its weakest feature, in addition to many times which distinction falls on the power supply in addition to related components. By choosing a quality power supply, surge protector, in addition to perhaps a UPS, one can make sure which they have adequately strong in addition to stable power to keep their system running right now, as well as down the road when upgrades may increase the demand on their system.
