Linear and Switch Mode Power Supplies

Choosing power supplies is one of the most important steps in building a custom computer. As the popularity of custom computer assemblies has grown, especially among the gaming community and computer enthusiasts, it is important to understand how to choose a power supply for the subsequent ingenious creation created as a portal to the Internet.

Without the heartbeat of electricity and a constant flow of power to handle the power built into a custom computer, even the best custom computers fall into the land of perpetual dormancy.

AC power supplies, switch-mode power supplies, and uninterruptible power supplies are all different options. The choice depends on what you need for your particular computer, as well as the voltage required to run your new gem. Visit also: Power supply for computers

What is the difference between linear power supplies and switching power supplies?

Linear power supply

A linear power supply is rarely suitable for a single computer. These types of power supplies require very large transformers and are very heavy. Unless you’re a champion bodybuilder who needs to prove himself, linear power is probably not what you need at about a pound per amp. Add to that the need for large heat sinks to dissipate power loss and an efficiency of about 50%, and linear power supplies are simply too bulky and inefficient to meet the needs of most home computers.

Switching power supply

Most enthusiasts choose something in the switching power supply category because they want a computer, not a high-powered championship power supply. This is due to the higher manufacturing costs. But these options are lighter and smaller – meaning they will fit in your home. Another advantage is that these power supplies are about 70-90% efficient. Since the goal is usually to run your computer efficiently, this efficiency rating is important when choosing a power supply.

This may sound confusing, but it is not. Switching power supplies use an AC voltage – 120 V or 220 V – for which the house is usually designed. There are no complicated devices that need to be connected to the house to use it. The main difference in the power supplies needed is choosing a power factor corrector. Rather than changing the outlets and wiring in the house to use a switch-mode power supply.

Need of surge protector

However, you may need to increase the power of the breakers if you are already overly reliant on them. When you plug in your latest creation. But that is to be expected with anything you add with the circuits available in the average home. Another necessity is to protect your computer from power surges with a proper surge protector. Other than that, there’s not much you can do to prepare your power choice.

If you’re still stuck, call your local computer store and ask them. There are many store employees who can help you decide and find what you need. Always consult a professional computer technician who has experience with networks and other computer hardware for reliable information and helpful advice that will make your computer power experience enjoyable.
