When building a new desktop system, most users pay little attention to an equally important component, the power supply unit (PSU). Usually, people want to spend most of their money on the main components of a computer such as the motherboard (Mainboard), processor (CPU), memory (RAM) and storage drive (HDD or SSD). ..
In addition, for graphic designers or gamers, spending a large amount of money on a new generation graphics card seems more reasonable than investing in a genuine power supply. However, tests show that the power supply also plays a more or less important role in the performance of the computer. It is where the power source for the entire system is provided. Therefore, please refer to the issues to consider below before choosing to buy an effective power supply for your computer system.
How much capacity do you need?
When planning to assemble a new computer, you can calculate the power consumption of components and then choose a power supply with the right capacity. Often times, you can overcalculate the expected number as a precaution in case of future upgrades. For users with only basic work needs, just an average computer with a power supply of about 400W is enough. But for users who are passionate about technology and like to “play around”, they should choose a large-capacity power supply to meet overclocking needs, add lights or decorative toys for the case, built-in water cooler. ..
Continuous power or peak power?
Currently, the power values printed on the power supply label usually come in two forms, including peak power (Peak Wattage) and continuous power (Continuous Wattage). Peak power is the maximum power (Maximum Wattage) that the power supply can meet in a certain period of time; while the continuous power is the effective power (Total Wattage), which is the power level at which the power supply can operate safely continuously.
For simplicity, the average computer user should only care about the continuous power level when choosing to buy a power supply and ignore the peak power parameter.
Efficient use of electricity
Technically, a computer power supply takes AC power from the mains outlet and converts it into DC current. The power is then transmitted to all the hardware components inside the machine that are connected to the power supply. However, power supplies often lose some power during conversion. Therefore, an efficient power supply is one that manages how much power it can convert and how to lose as little as possible. An additional advantage of efficient power supplies is that they generate less heat during operation and are generally quieter.
Why not choose a cheap power supply?
A good power supply must be able to supply the “standard” current to the components. In other words, the issue of current stability must come first. Choosing the right power supply will bring stability and long life to the entire system. Therefore, you should consider carefully when you see a power supply with a high announced capacity but the price is too cheap. Quality is always proportional to cost, that’s why you should choose products from reputable manufacturers. Large companies often launch a wide variety of products, rich in designs and features for users to choose from to suit their needs.
