5 Factors to Look at Before Buying a Computer Power Supply

Selection of a computer power supply is a straightforward affair, provided you are not making blunders, which other people are committing. One of the common mistakes buyers made when making their PC is to neglect the significance of the computer power supply. They make a cut on their budget on the computer power supply and get the cheapest one. If you care about your system, you need to put in serious efforts to choose the best power supply from quality power supply manufacturers.

A power supply is an energy source for the entire computer system. Imagine you are avoiding eating a proper meal on time, do you think your body will still function well for your daily tasks? Obviously no!

So, the following are the aspects you need to know before buying a computer power supply:

Power Rating

While folks discuss the storage gigabytes, 64-bit processing capacity along with the heavy-duty 3D graphics card are the components that get the most attention. However, the computer power supply is the least discussed.

What they don’t realize is that if they have to have a powerful computer, the more power you need to provide. If you are in the process of assembling a high-end gaming computer, there are chances you might require a 600 – 650W power supply.

Mean Time Between Failure (MTBF)

MTBF refers to the life of a power supply device. It shows the average hours’ power supplies can perform before they fail. Most power supplies have MTBF ratings equal to or more than 100,000.

Short Circuit Protection

When purchasing a computer power supply, make sure it has a short circuit protection feature. This is done to prevent the computer parts from drawing too much current, which could cause the internal chips to burn.

Low Noise

The important reason for a power supply being noisy is its inability to dissipate heat fast. Its fan needs to work extra hard for maintaining the desired temperature. When selecting a power supply for a computer, make sure it has a massive powerful 140mm fan or double 80mm fans for dissipating the heat away effectively.

Load Current (Maximum and Minimum values)

Each part of the computer needs a different current and voltage to function. The power supply must support various voltage levels along with 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 receiving the minimum load current from the power supply, the power supply is most likely faulty.

Last Word

The power supply is a computer part that every potential buyer must pay attention to. When picking a PC power supply, try to get a power supply that offers a higher power rating than your system needs. Also, unless you are happy to put your computer at risk to system jeopardizing power surges and spikes, do not scrimp on the power supply.
