Power Supplies

The main purpose of power supplies is to convert power from the input to the output. A power supply is not a power source, the source is an outlet, battery, and even generators. A power supply changes the voltage and converts power. This happens so that the power coming out of the output is regulated and safe. The power supply is connected to the motherboard, which then connects to the rest of the system. The 24-pin connector is what connects the power given from the output to the motherboard.

A power supply is made up of an electronic circuit. The electronic circuit is made to convert the voltage of the inputted current. After it converts the voltage it directs the current to the output. The power supply is made of four main components; the transformer, rectifier, filter, and the regulator circuits.

The history of the power supply can date all the way back to 1926. The first development of the power supply actually called a "B" battery. Its purpose was to power radios. Some Brief history of the power supply also includes the power cable the Thomas Edison created back in the 1800s. He was developing power distribution and he had to start with a power cable to distribute the power. In the 1970s there was an energy crisis That affected the majority of the industrial world. By using the power supply held an opportunity to greatly excel in the market.

The first thing to talk about is how to remove your power supply. But before that you must know that you cannot fix your power supply, you will have to replace it. You should not open your computer power supply to attempt to fix yourself, power supplies have lots of energy flowing through it so you could accidentally hurt yourself. First thing is to start off by removing the power supply from the motherboard, to do this you must remove the 24 pin connector. After doing that you will have to unscrew the power supply from the PC. The next step would be to remove the power supply cable from the PC. To install the power supply will be doing the exact things I listed but in the opposite order, first, you have to start with putting the power supply plug-in, then inserting your power supply, then connecting it to the motherboard. In regards to upgrading, you can buy different power supplies and put them in the same way as any other power supply.

The power supplies may be programmed locally through keypads or remotely on analog or digital devices depending on the architecture. Analog approaches include external voltage, current resistance systems. For an external controller or PC located and the software. Many supplies use a control architecture based on microprocessors and rendering them internally or externally.

There are four form factors of the power supply. The first is ATX which we talked about a lot in this class. The second one will be ATX12 v1 x. The third one will be ATX12V v2 x, and the last one will be the micro ATX. Although they are very different they do have very similar qualities and all can be used if you want to.

In order to have a power system with fault tolerance, you will need multiple converters that will configure power to maintain the same output in power as the input. You do need multiple power converters just because if there is a failure that is a single point it doesn’t affect the whole thing it will still be able to work even if there’s a failure that can be reworked. These multiple power converters also help with the ability to keep working without interruption.

There are many symptoms that can be related to a common power supply issue. The first symptoms could be that the system fails to start-up or it locks up. Another one could be a reboot out of nowhere during an activity on the PC. Another one is the fan both failed to spin, the fan affects overheating because of the fan failure. Many of these could happen just because the power supply needs to be replaced. Or it could just be a faulty power supply that was sold to you by the merchant.

Many different tools for a power supply one is needed to figure out how much power supply you’ll need for your PC. This tool is called the power supply calculator can be found on almost any website that involves computers. This calculator is needed because calculating it manually will take a very long time because you will need to multiply amps of all components in the total voltage of all components. The result will be the total watts that your PC will need. Another thing you’ll need is a power supply tool station. This tool station can come with different power cables and plug adapters. It helps up tremendously just because it can be compatible with your PC much more easily. This allows you to adapt to different parts of your PC and have specific power cables that you will need.
