Buying Computer Power Supplies

Buying a computer power supply is easy, provided that you are not making the mistakes that other people are making.

One of the most common mistakes people made when building their own computer is to neglect the importance of computer power supply.

They tend to cut down their budget on computer power supply and get the cheapest one around. If you really care about your computer system, you have to put in some serious effort to choose the best power supply.

The computer power supply is the energy source for the whole computer system. Imagine that you are not eating well for every meal, do you think you can still function well for all your daily tasks?

Power Rating

While people are discussing about the gigabytes of storage, 64 bit processing capabilities and the heavy-duty 3D graphics card, the only thing that required the most attention, but is discussed least is the computer power supply.

What they have not realized is that the more powerful a computer become, the more power it needs. If you are building a high-end gaming computer, chances are you may need a 600 - 650W power supply.

Mean Time Between Failure (MTBF)

This refers to the lifespan of the power supply. It represents the average hours the power supply can perform before it fails. Most power supplies will have MTBF ratings of 100,000 hours or more.

Short Circuit Protection

When choosing a computer power supply, make sure that it is equipped with a short circuit protection feature. This is to prevent the computer parts from drawing excessive currents which might cause its internal chips to be burned.

Low Noise

The main reason for a power supply to be noisy is because of its inability to dissipate heat fast. The fan has to work extra hard to maintain the required temperature. When choosing a computer power supply, make sure that it comes with a big powerful 140mm fan or two 80mm fans to effectively dissipate the heat away.

Load Current (Maximum and Minimum values)

Each computer part requires different voltage and current to function. It is important that the power supply can support the various voltage levels and the current supplied.

Maximum load current - The maximum current that the computer part can accept for a particular voltage level

Minimum load current - The minimum current the computer part needs to be functional.

If the part is not getting the minimum load current from the power supply, chances are the power supply is spoiled.

Form Factor

Most of the power supplies in the market are of the ATX form factor. However if you are using a micro ATX computer case, you have to get a micro ATX power supply, else it won't be able to fit inside the case.

Conclusion

Power supply is definitely a computer part that you must pay attention to. When choosing a computer power supply, always get a power supply that has a higher power rating than what your system needs.

In addition, unless you are willing to risk your computer to system jeopardizing power spikes and surges, do not ever scrimp on the power supply.

Online Uninterruptible Power Supplies

Ensuring uninterrupted power is a vital part of any organisation's business continuity planning and can be achieved with the correct deployment of a suitable uninterruptible power supply.

Different types of UPS can be used as stand-alone solutions or in conjunction with one another other.

The three main static UPS topologies are as follows: Online or Double Conversion VFI , Line Interactive VI and Offline or Passive Standby.

So what are the main characteristics of an Online UPS? The only UPS for completely break-free supply An online uninterruptible power supply maintains power voltage and frequency variations within prescribed limits and is independent of any fluctuation in supply.

It's not just complete power failure that can affect a modern power-hungry business. The online UPS also conditions mains power to counter the potentially damaging consequences of sags, surges and other everyday power problems.

Because of this combined power protection and power conditioning capability, the online UPS is the preferred choice for critical data and voice processing systems and remote mobile telecommunication sites where there may be a high risk of damage from local lightning strikes and high-energy transients.

Furthermore, an online UPS can also act as a frequency converter providing 50/60Hz or 60/50Hz. There are also solutions for 400Hz applications.

Of the three main UPS topologies, the online uninterruptible power supply is the only one that can provide completely break-free protection if the mains supply should fail.

And, in the event of the UPS developing a fault or suffering an overload, the online UPS is designed to deliver safe failure to mains. This is achieved through an automatic system bypass.

Typical online UPS applications. Online UPS from manufacturers such as Riello UPS are typically used for specialist operations. They can be easily modified using a range of accessories and 'small batch' production techniques.

Typical applications for the online uninterruptible power supply include the following: Rail equipment requiring extended runtimes, Remote telecom sites, Industrial applications requiring specialised air filters, Water treatment works requiring UPS with raised plinths and high ingress protection.

Scientific sites at altitude or in tropical areas, Military applications requiring ruggedised assemblies, Remote sites where only renewable energy sources are available and Medical applications requiring isolated supply.

Online UPS are particularly suitable when it's necessary to expand large-scale Power over Ethernet (PoE) implementations, requiring an upgrade to the current level of UPS protection.

Maybe the existing uninterruptible power supply is no longer large enough to power the entire infrastructure or, as in the case of a telecom application with existing line interactive UPS installation, perhaps the available runtime duration is not long enough.

When business continuity planning has reached this stage, it may be time to upgrade to an online UPS for maximum power protection.

Sizing an online UPS for current and future needs. Regardless of the application, correct sizing is essential to avoid over- or under-specification that wastes resources or leaves parts of the network vulnerable.

Then, once the current load requirement has been correctly established, it is prudent to include an allowance for future expansion. The most common approach is to allow for 25% load expansion within five years.

For online UPS, additional capacity, along with higher operating resilience, can be achieved by adding more modules into an existing system using a parallel architecture.

Whatever the requirements of a business's power continuity plan, and whatever the eventual uninterruptible power supply solution, the first step should always involve seeking the advice of a reputable UPS manufacturer with a proven track record in power protection. Whether for an online solution or one of the other UPS topologies, a modern consultative UPS specification process ensures that uninterrupted power for mission critical facilities are easy to achieve.
