The consequences of choosing the wrong power supply

The power supply of our PC is much more important than many think and here we will detail why it is importable to choose a quality one.

Choosing a bad power supply can cause you all kinds of problems: on the one hand, it won't supply clean energy to your components; which will result in bluescreens, reboots, and premature degradation of components connected to it. On the other hand, if the PSU does not have its protections well configured, or (if it does not even have such protections), as soon as an unwanted situation arises, (which may be due to user error, failure of a component within the PC or problems associated with your home's electrical supply), at least you'll have a burned-out PSU; but it is not uncommon for this to ruin other parts of your computer as well. There have even been cases where the PSU catches fire and causes a fire.

After reading this, you will have realized that Saving too much on this piece can end in monetary or even human losses! The truth is that most of the time we do not reach these catastrophic situations, but we should not stay with the idea of ​​saying "nothing happens, I have had a generic font for many years and my computer continues to work»

As I explained, many people rely on their particular experience to suggest that you don't need to spend a lot of time choosing a power source. In fact it is possible that some of you are based on the opinions of stores like Amazon, newegg, PCComponentes, etc. to choose your power source. Then I explain why the experience rule is not valid for purchasing PSUs.

Let us remember that the sources, unlike other components, are not pieces that can be compared so intuitively; things like texture, ergonomics, or even quantitative values ​​like FPS, resolution, refresh rate, image quality are completely unrelated to the world of switched power supplies (the technical name for PSUs). I reiterate, the power supply has two main functions: to deliver the correct and stable power to the equipment; and protect the source, the equipment and yourself if something goes wrong.

You can use a generic font and when seeing that the PC turns on and works as if nothing; think that everything is going well, even if it is not like that. But electrically you do not perceive what is really happening, and this is how your power source sees it:

This graph represents the ripple (ripple) that is the voltage fluctuations that occur in milliseconds.

Your components could well be receiving inadequate or unstable voltages; something that you will not perceive at first until your computer begins to give problems or directly stops working. Regarding the protections; We can use the analogy of a car seat belt: you can drive a car without it, but in the event of an accident the seat belt saves your life. Similarly, a power supply can function without safety protections; These save the life of the PSU itself as soon as there are problems; to the PC and to yourself too.
