The Essential Guide to Choosing a Power Supply for your computer

Although power supply unit is one of the most important components of a computer, it is one of the most overlooked because many underestimate its potential. When it comes to a selection of power supply, it can make a huge difference between a well-functioning computer system and a faulty one that is prone crashes, boot failures, and other problems. While each computer build has its own unique power requirement, it is important to get the right power supply to prevent other issues from happening. This is what you should look for before going to buy a power supply for your computer.

Overall Wattage

As it refers to how much overall power a system needs to function well, overall wattage will determine how you choose your power supply. If you want to calculate overall wattage, you can find several power supply calculators on the internet. When in doubt, it is always best to aim high and overshoot because oversized power supply can power undersized system easily. In addition, it makes it easier and cheaper option if you plan to upgrade your system in the future.

Rail Specific Power

When you plan on a certain computer build, it is necessary to calculate the rail specific power. It is a measure of how much power certain components in a build draw from the connected power supply. Most of the time, you will see this applies to how much power a large component such as graphic card can pull from the power supply's main +12V rail. Most mainstream computer builds with one or two mid-range graphic cards will not have rail specific power problems. If you plan on using high-end graphic cards, you should always refer to manufacturer's specifications for how much power a particular graphic card requires. At the same time, you must check on whether your power supply can fulfil the requirement.

Rating

In terms of rating, you need to consider about long-term energy savings. If you are looking for the efficiency standard for power supplies, you can refer to 80Plus certification standard. Based on this certification standard, it sets out the criterion of a highly efficient power supply. A good power supply with 80Plus certification offers greater efficiency for both provider and customer while prevents energy from being wasted. With this power supply, you can also enjoy better voltage regulation that leads to the consistent and stable performance of your system. Furthermore, you can save more energy and money at the same time.

Design

You can always choose the visual design of power supply that matches the color theme of your build. As each person has his or her own style, the best question that you can ask yourself is how your whole computer build will look to you. Instead of a ugly power supply at the bottom of the computer case, you can always opt for other gorgeous power supply designs. In fact, it can be used as an accent to your beloved rig. Contrary to popular opinion, motherboards and power supply have nothing to do with each other. However, you definitely need a suitable motherboard that can fit well with your specific build.
