What is a PSU?

The power supply unit (PSU) is the piece of hardware which takes the power provided from the electrical outlet and distributes it to all the components of your computer. Additionally, it also regulates overheating by controlling voltage, which might change automatically or manually depending on the power supply.

Where is the PSU located?

It is mounted inside the back of the computer case. In actual fact, if you follow the power cable, it actually joins the power supply. The side of the PSU which faces the outside of the case has a three-pronged port that a power cable, connected to a power source, plugs into. In some cases, there is also a power switch and a voltage switch next to each other.

How are PSUs rated?

Power supply units are rated by wattage to show how much power they can provide to the computer. Since each computer part requires a certain amount of power to function properly, it's important to have a PSU that can provide the right amount. There are actually power calculators online which can assist you, but if you are having difficulty, then here at Ebuyer we have online specialists who can help you, with online chat.

How many watts do you need?

Let us presume that your system needs 500W at full capacity, it is not wise to get a 550W PSU but, go for a 650W one at least. That said, most gamers are not constantly playing games around the clock to put stress in their systems. Gaming can be seriously taxing on your PSU since they will generally fully load your graphics card, which is likely the most power-consuming part of your setup.

As you would expect with anything that deals with large amounts of power, system safety is important. A good power supply needs to have fail-safes built in, not just to protect the PSU itself, but also to keep your system safe just in case there is a power surge or something unexpected happens. The PSU and motherboard are the only PC components which directly connect to almost every other piece of hardware in your system. Because of the unique position of the PSU in the layout of a PC, making sure it has built-in protection can help keep the rest of your hardware safe too.

A Power Supply Unit with this wattage will deliver more power to your computer components. If you are planning to upgrade your PC at some point it is always worth getting a PSU with more power than you need now to make later expansion easier.
