500W PSUs

500W PSUs are the perfect for converting power for your system. Make sure you check the requirements of your system before you buy though, as your PSU will need to account for more than half of your PCs requirements.

What PSU do you need?

What PSU do I Need? This is one of the most popular questions asked in the hardware community, especially from those who are just starting out and putting together their first PC or from those who are just learning about hardware. A power supply is also known as a PSU and without it, your computer would not work! The PSU is the only component which provides power to all the internal components. These include the CPU, motherboard, graphics card and more.

How to select the right PSU?

This can be a very tricky thing for some users as they are available in different form factors and different wattages. Anything can be confusing when it is new to you. There are also other factors which can influence your design. If you make the wrong decision in buying the correct PSU then you could easily face compatibility and instability issues. So, it is wise not to rush in and buy what you think is the correct PSU unit. Do some research.

Other factors

Capacity, power and wattage of the power supply are all important considerations. Estimating the wattage of the power supply can be a little confusing as you need to know about the total power consumption of your PC, and how many people really know that? There are some tools that can help inform you about the capacity of the power supply that you are going to need.

PSU calculator

To get a rough idea about the capacity of the power supply you are going to need, you can use an online PSU calculator tool. You select the components present in your PC case, hit the calculate button and the tool calculates the total power used by your PC at full speed and then recommends what Wattage PSU you need. These tools work reasonably well, but you can always speak to an Ebuyer specialist online to ensure you get the right PSU for what you need.
