Motherboard Or Power Supply Unit?

Choosing the right power supply unit (PSU) is a critical step for any system builder. A bad PSU can cause all sorts of problems, from making noise to catching fire. In this blog post, we’ll go over some different types of PSUs and help you find the one that’s best for your system!

PCIe power cables are a good way to get the most juice out of your PSU. This is because they offer more amperage than standard SATA or Molex connectors, meaning you can get away with having shorter cords which reduces cable clutter and improves airflow in your case.

Introduction of Power Supply Unit

A power supply unit (PSU) converts mains AC to low-voltage regulated DC power for the internal components of a computer. Modern personal computers universally use switched-mode power supplies. Some power supplies have a manual switch for selecting input voltage, while others automatically adapt to the mains voltage. Most modern desktop personal computer power supplies conform to the ATX specification, which includes form factor and voltage tolerances. While an ATX power supply is connected to the mains supply, it always provides a 5-volt standby (5VSB) power so that the standby functions on the computer and certain peripherals are powered.

Motherboard or PSU

It’s also important to choose a PSU that offers the right power output. If you’re building an overclocked system with multiple graphics cards, for example, then it might be worth spending a little extra on a high wattage unit that can keep up with your hardware demands.

The form factor of the PSU is another important consideration. Tower units are ideal for smaller builds, while ATX models offer more space and a modular design that’s great for cable management. You also need to make sure your power supply can handle all of your expansion cards–don’t just go with the cheapest option!


A motherboard (also called mainboard, main circuit board,[1] or mobo) is the main printed circuit board (PCB) in general-purpose computers and other expandable systems. It holds and allows communication between many of the crucial electronic components of a system, such as the central processing unit (CPU) and memory, and provides connectors for other peripherals. Unlike a backplane, a motherboard usually contains significant sub-systems, such as the central processor, the chipset’s input/output and memory controllers, interface connectors, and other components integrated for general use
