Is it possible to use 2 power for computer?
Considering that the latest processors and graphics cards consume a lot of energy, you may have thought that instead of buying a much better power supply, use a new normal power supply next to your old computer power supply. But is such a thing possible? We will discuss this issue further.
The reason for using two powers
At the very beginning, we must note that we are not talking about systems that use two powers. But only one of them is used. In servers, we usually see the implementation of such an approach where two power sources are used to prevent untimely blackouts. In such a situation, if one power fails for any reason, the second power will take its place very quickly. For people who might be looking to implement such a feature, we can put forward two main reasons.
First First of all, we should mention the systems that, due to the high energy consumption, a power supply cannot supply the required energy in any way. For example, cryptocurrency mining systems that use several graphics cards, naturally, only one power supply cannot supply the required energy. In this situation, one power supply should supply the energy of the graphic cards and another power supply the energy of the remaining components. If your system is using adequate power without any problems, naturally you don't want to abandon it due to the upgrade of the graphics card or processor. Therefore, in this situation, by buying an affordable power supply and placing it next to your current computer power supply, you can significantly save money.
Disadvantages
But if such a thing is possible, then why many users for their system from two power do not use Regarding the disadvantages of using this method, we can mention many things. First of all, we should note that desktop computers are not designed and built to use two power supplies. The motherboard is originally designed to supply energy from only one power source, and therefore, in order to use two power sources, you must use solutions to bypass this limitation.
Besides the technical limitations, you must Let's also mention the limitations related to the space of the case. If you are looking to use secondary power, where do you want to put it? Computer cases are designed to host only one power supply. But in the meantime, you can buy cases for very professional systems that offer enough space for two power supplies. But for users who are looking to save money, such a solution does not work. Because if you have enough budget to buy such an expensive case, then it is better to buy a much more powerful power for your system so that you don't need to use dual power anymore.
So if you don't want a giant case for power Buy dual, you'll end up having to put the power somewhere, which means your system won't have an attractive design and is a temporary solution at best.
How does it work?
Now despite all these conditions, we assume that all You accept these limitations and finally want to do something like this. But how do the two powers work together? As we said a little above, motherboards can control a power supply at any time. This is done through the ATX connector, which is a 24-pin port on most motherboards. So even if you connect secondary power to the graphics card, it won't work without receiving the proper signal.
Years ago, techies and tech geeks used paper clips or soldered wire to communicate between connector pins. ATX used to provide power on signal. Then, using the power switch on the back or the switch on the outlet, they controlled turning it on and off. Using this method required a bit of finesse as both power supplies had to be turned on at the same time, otherwise there was a risk of system instability or failure. Even with the great care of these people, sometimes the secondary power went out or had trouble working.
But one of the better solutions is to use ATX adapters to connect to two power supplies. This interface allows your motherboard to connect to and control two power supplies simultaneously. Of course, in the reviews of these interfaces, some have stated that there is a possibility of melting and even catching fire, and therefore you should also consider this issue. It should be noted that the power of two powers enables the control of both powers for the motherboard, and the board itself does not face any additional heat. Therefore, using these boards is less risky and is the easiest and best solution for using two power computers at the same time. Although using two power supplies at the same time can have various advantages, we generally do not recommend doing this. Fortunately, powerful power supplies have a much lower price than components such as processors and graphics cards, and for this reason, by using a powerful power supply, you will get rid of the possible problems of using two power supplies at the same time.
