Understanding Power Supply Basics

Delving into the intricacies of power supply basics, it’s paramount to understand that wattage plays a crucial role, dictating the power needs of your components and influencing your choice of a power supply unit (PSU). A PSU with insufficient wattage may lead to system instability or even damage. Therefore, selecting a PSU that offers sufficient wattage to meet your requirements–with a bit of headroom for future upgrades–is an essential step in building or upgrading a PC on a budget.

Understanding the 80 Plus ratings is equally critical. This independent certification guarantees that the PSU will operate at a certain level of efficiency at specified loads, resulting in less wasted power, potentially lower energy costs, and increased reliability.

The form factor of the PSU is another fundamental aspect to consider. Different form factors like ATX, TFX, SFX, and SFX-L cater to varying PC sizes and build requirements. Choosing the right form factor ensures compatibility with your system and impacts your build’s overall aesthetic and cable management.

Key Features of Budget PSUs

Having understood the basics of power supplies, we now turn our focus to the specific features that characterize budget-friendly PSUs, primarily those priced under $100, which strive to balance affordability with performance.

A key aspect of a budget PSU is its efficiency ratings. High-efficiency PSUs can save on electricity costs in the long run, and many budget PSUs feature 80 PLUS Bronze or Silver ratings. Modularity options, such as semi or fully modular designs, offer a cleaner setup and easier cable management. However, non-modular budget PSUs may be more affordable.

Warranty coverage is another critical factor. Reliable brands tend to offer a minimum of 1-3 year warranties, ensuring some peace of mind after purchase. The inclusion of quality capacitors in a budget PSU is particularly important. These components ensure stable power delivery and longer lifespan, which ultimately contributes to the overall value of the PSU.

Top PSU Brands to Consider

In the realm of budget-friendly power supply units, brands such as Seasonic, Corsair, and EVGA emerge as noteworthy contenders due to their proven reliability and quality offerings.

Seasonic is recognized for its unwavering dedication to manufacturing power supplies that meet the highest industry standards. Their products deliver consistent output, ensuring optimal performance of your system components.

Corsair, another trusted brand, has a solid reputation for offering a range of PSUs at budget-friendly prices. Their CX series, for instance, is lauded for striking a balance between cost and performance, making it an ideal choice for users on a tight budget. The brand’s commitment to quality is evident in the durability and efficiency of their units.

Lastly, EVGA is a viable option for those seeking budget units. Despite some questions regarding their quality compared to other brands, they offer reliable units under $100, representing considerable value for money.

Factors Influencing PSU Prices

When evaluating the cost of a power supply unit, several key factors come into play. These include wattage, efficiency ratings, modularity, brand reputation, and warranty length. The wattage directly impacts the price, with higher wattage units costing more due to their increased power output capabilities for demanding hardware configurations. Efficiency ratings, like 80 Plus Gold or Platinum certifications, also affect the cost, as units with higher efficiency may have a higher initial price but can save energy costs over time.

Modularity is another important factor to consider. While modular PSUs are typically more expensive, they offer superior cable management, resulting in a cleaner and more efficient internal layout for your PC. Brand reputation is also significant, as renowned brands may command higher prices due to their track record of quality, reliability, and customer service. Lastly, warranty length can influence the price, with units offering longer warranties usually costing more but providing added peace of mind regarding the product’s longevity and performance.

Selecting the Right PSU for Your Needs

Understanding the intricacies of PSU prices enables us to make more informed decisions when selecting the right power supply for our needs. When shopping for budget PSUs, the first step is to consider the power requirements of your PC components. This will dictate the wattage you need from your power supply. Brands like Corsair, EVGA, and Seasonic offer reliable power supplies under $100, striking a balance between affordability and performance.

Efficiency is another crucial factor, often indicated by the 80 Plus rating. A higher rating means less energy wasted as heat, more savings on electricity, and a quieter operation. Budget PSUs with this rating deliver a reliable and efficient performance. Please check out the product comparison of 450W vs  550W Power supplies.

Modular design is another aspect to consider. While fully modular power supplies offer maximum customization, they come at a higher price. Semi-modular or non-modular options may suit your budget better, but offer less flexibility in cable management.

Lastly, consider the wattage headroom, a larger capacity than your PC’s demand. This ensures stability and can handle power spikes, protecting your components. Balancing these factors effectively guides you to the right PSU for you.


In conclusion, selecting a budget-friendly PSU necessitates a thorough understanding of power supply basics, such as wattage and efficiency. Top PSU brands, including Corsair, offer quality options that simultaneously satisfy budget constraints. For more please visit Power Supply price in Sri Lanka.
