Power Supply Unit ( PSU )

A Power Supply Unit (PSU) is a very important component in a PC build that is, more often than not, not given enough importance by those who are not too well-versed about PC components. The logic is that a power supply unit’s only work is delivering power to the components of the PC. However, what they fail to understand is that unstable electricity can be dangerous for the components.

That is why it is always recommended to use quality power supply unit PSU from reputed brands. The power supply unit PSU from reputed brands come equipped with high-quality components such as Japanese capacitors, better transistors, coils, and other internal components, along with features such as Active PFC. This does not only make the current flow more stable but also avoids the risk of your PC components getting damaged by unstable current flow.

There have been many events where a cheap, sub-standard PSU has ended up not only got damaged under load but also ended up in damaging some of the expensive components inside the PC such as the graphic card. So, it is always recommended to opt for branded power supply unit PSU. When it comes to choosing the right power supply unit PSU for your PC, you need to check which components are you using, or planning to use.

If it consists of mostly entry-level hardware, then a 450 to 550 Watt PSU would be more than enough. However, if it consists of higher-end PC components such as a powerful graphic card, and powerful multi-core processor, then you should opt for higher wattage. These days a 750W to 850W PSU is more than fine for single-card PC builds. You need to go above the 1000W mark if you are using multiple cards, and there is a requirement for more amount of power.

In terms of efficiency, it is always better to opt for those that have the 80 Plus certification. This is an efficiency certification. It comes in various grades, Standard, Bronze, Silver, Gold, Platinum, and Titanium. The higher it is the better the efficiency is. And, the better the grading, the more expensive it is. But, for most mainstream consumers Bronze, Silver, and Gold are just fine.

Frequently Asked Questions (FAQ)


What is the difference between linear and switch mode power supplies?

The linear power supply works by first converting high voltage AC to low voltage AC, and then converting it to DC. Whereas, switch mode power supplies directly convert the high voltage AC to DC first, and then lowers the voltage as per requirement.

Why do power supplies require power factor correction?

Power supplies require power factor correction (PFC) to improve the quality and efficiency of the power delivered to the internal components of the PC. Active PFC plays an very important role, and is always recommended to opt for PSU that have this feature.

How to pick the best power supply unit?

The best power supply would be depending on the budget, and the requirements. But, for most users, a 650W PSU would be more than enough. If the Pc is running higher-end components, then it would be better to opt for higher wattage PSU.

Can I change my shipment method?

Yes, depending on your requirements, you very well can. All you need to do is contact us, and tell us how you would like to get it changed. Depending on the request, additional expenses might incur.

Is it worth paying more for the Power Supply Unit Products?

Absolutely yes. A power supply unit PSU is a very important part in the PC component. So, it is always better and definitely worth it to pay more for a power supply unit PSU. Users should opt for a PSU that has higher wattage support, higher-grade efficiency certification, uses premium, and durable internal components has important features like PFC, and most importantly, is from a reputed brand.

Power Supply Unit (PSU) is one important component that is often not thought of much while getting a new computer. However, that would be a horrible mistake. Here is why, PSU just as the name suggests is the component responsible for delivering power from the socket to the other important components such as the processor, graphics card, etc. Now, if you are using a bad PSU, it is very risky, as due to faulty power delivery, the Power Supply Unit ( PSU ) can short and fry itself.
