Hello Steem Skillshare and her Members, I greet you all...
If you're a computer engineer you need to read this content. In this content, I will elaborate on Computer Power Supplies!! Just follow me and we will acquire this knowledge together. So let's dive in...
Power Supplies
Before a Computer can work, it needs some power supply. Computers have a power supply that converts electricity from your volt to something usable.
There are two types of electricity, they are: Direct Current (DC) and Alternating Current (AC).
Direct Current is a type of current that flows in one direction.
Alternating Current is a current that changes direction constantly.
Our Computers use DC voltage, so we have to have a way to convert the AC voltage from our power company to Direct Current. That's what our power supply unit does i.e it converts Alternating Current voltage coming from our power company to Direct Current (DC) voltage coming for our computer to use.
The power supply unit converts the AC we get from the wall into low voltage DC power that we can use and transmit throughout our company. The amount of electricity coming out from the wall outlet is known as current and it is measured in (amps). We can think of amps as pulling electricity as opposed to voltage, which pushes electricity. Amps will pull as much as electricity needed, but Voltage will just give you everything.
*Note: Charging a device with 2.1 amps will actually charge a device faster because it's able to put current from a 2.1 amps than a 1amp charger. Another important part of electricity is the Wattage.
Wattage is the amount of volts and amps that a device needs. If your power has a too low of a Wattage, you won't be able to power your computer, so make sure you have enough. This doesn't mean that if you have a large power supply, you'll overpower your computer. Power supply unit just give you the amount that your system needs. It's best to error on the side of large power Supplies.
Bonus
You can power most basic desktops with a 500 watt power supply, but If you're doing something more demanding on your computer, like playing a high-resolution video game or doing alot of video production and rendering, you'll likely need a bigger power supply for your computer. On the other hand, if all you're doing is just browsing the web, the power supply that comes with your computer should be fine. All kinds of issues are caused by a bad power supply. Sometimes, the computer doesn't turn on at all. Power Supplies can fail for the following reasons like burnouts, power surges, or even lightening strikes!
Thanks for reading through. I believe you learnt something new today! Wish you Good luck!!!
