The power supply (PSU) is a vital part of the computer. Computer power is responsible for powering all the components in your case, and if there is a problem with it, then other hardware will be affected. 

PSU, Below we are going to tell you the important things while buying computer power.

The power supply is an essential component of your computer

When we turn on the lights, turn on the tap, or walk on a clean sidewalk, we may never think about the infrastructure that has made this possible. If one does not pay attention to the infrastructure and does not build it, then naturally the situation will not go well.

The same is true of a computer case. Most users are more concerned with how many cores their computer processor has or how many processing units their graphics card should have.

In the meantime, less attention is usually paid to items such as the power supply, which is responsible for powering other components. Of course, we are not saying to pay too much attention to your computer power.

But if you do not pay much attention to it while shopping, then after various problems occur, you will have to pay more attention to this issue.

If your computer’s power supply does not have the required power or has a problem, then it is natural that problems will arise for your computer.

Your system may not boot, your entire system may be malfunctioning, or your computer may even shut down due to excessive power demand.

Other hardware can also be damaged due to these instabilities. The good news is that you don’t have to go into too much detail to buy the right power supply. There are also online tools that can help you buy the right power supply PSU.

What

The amount of watts of power output of a power supply plays the same role as the number of cores in a processor. Output watts are an important indicator that many users pay attention to. It is best to have at least 25% more watts of power output than your computer needs.

For example, if the maximum output power you need is 400 watts, then a power supply of 500 to 550 watts will suffice. You can also save yourself a new power supply when you buy more powerful hardware in the future.

So how do you get the output power you need now? A website like Newegg can show you the amount of power required depending on the components selected. Of course, if different tools give you different results, do not worry too much, because these numbers are estimates.

Another thing we need to address before concluding this chapter is the importance of rails in a power supply. You may have heard about the importance of this from those around you. Of course, it should be noted that this factor is no longer as important as before.

Ranking

Most likely, when you buy a power supply, you will come across a phrase like 80 Plus and the name of one of the metals Bronze, Silver, Gold, Platinum and Titanium. Of course, sometimes only the 80 Plus rating is mentioned, so no metal is mentioned next to it.

The above are related to performance and reliability. 80 Plus means that your power supply can operate at 20, 50, or 100 percent of its power and at 115 and 230, 80 percent, or more when powering other hardware.

Performance requirements vary depending on capacity and voltage. The more valuable the metal named in your power rankings, the more efficient your power supply PSU will be.

For example, an 80 Plus Bronze power supply is expected to perform at least 85% at 50% power and 115V. However, a Titanium power supply in the same condition should be able to be up to 94% efficient.

One of the reasons for these rankings is that computer power supplies, like other electrical components, are not 100% energy efficient. In fact, your computer’s power supply also loses some of its energy as heat. The number of watts written on your power supply box is its maximum operating power.

One thing to keep in mind when it comes to better understanding metal standards is that the higher the grade of metal written on your power supply, the better performance you can expect. In general, you should provide a power supply that, considering its efficiency, can deliver the amount of watts you need.

Other important features in computer power PSU

Whether you are buying a new computer or replacing the power of an old computer, there are other things to keep in mind. The first is whether the power is modular, semi-modular or non-modular.

A modular power supply has no connected cables and is sometimes referred to as “all modular”. Thus, all the required cables must be connected to the power supply manually. Semi-modular power supplies also have a number of cables that are not detachable.

Non-detachable cables are usually the main cables, such as a 24-pin cable, CPU connector, and so on. If you need other cables, then you can connect them manually. Finally, we must mention the non-modular power supplies.

None of the cables in these power supplies can be disconnected, and of course you can not connect another cable to them manually.

The advantage of all modular power supplies is that you can prevent unused cables from connecting to your power supply. You can still do this with a semi-modular power supply.

Non-modular power supplies are cheaper than the other two models. Of course, in addition to this advantage, you also have to deal with unused cables in your case. In any case, if you can, then it’s best to have at least one semi-modular power supply for a more regular case.

We also recommend that you buy from a reputable brand. There are several brands on the market that you have not even heard of.

If your power supply is not of the required quality, then it will break down sooner and may damage your other hardware in addition to itself. Companies such as Corsair, EVGA, Cooler Master and Thermaltake are well-known names in this field.

Naturally, the products of these companies will be of better quality compared to unknown companies.

Finally, we suggest that you also consider the issue of warranty. The power supply warranty is more important than other components.

Products that have a multi-year warranty give you the confidence that you can count on them to upgrade your hardware in the years to come. If your power supply has a problem during the warranty period, then you can take advantage of its warranty benefits.

Above we tried to tell you the important points in buying a power supply PSU.

Keep in mind that if your computer’s power supply fails to provide the power needed by the hardware, then you will not be able to get the processing power you expect.
