In 2026, power supply units (PSUs) for gaming and high-performance PC builds are more efficient than ever. SFX-L PSUs with Gold and Platinum certifications are popular choices for compact yet powerful systems. This guide provides an overview of the top options, their features, and what to consider when choosing a PSU for your setup.
Understanding SFX-L PSUs
SFX-L PSUs are a variant of the standard SFX form factor, offering a larger size that allows for higher wattage and better cooling. They are ideal for mini-ITX builds where space is limited but power requirements are high. The ‘L’ indicates the extra length, providing more room for components and improved airflow.
Efficiency Certifications Explained
Efficiency certifications such as Gold and Platinum indicate how well a PSU converts AC power from your wall into usable DC power for your PC. Higher certification levels mean less wasted energy and lower heat output, leading to quieter operation and better energy savings.
Gold Certification
Gold-certified PSUs typically achieve 87-90% efficiency at 20%, 50%, and 100% load. They are a popular choice for most users, offering a good balance of performance and cost. Many 2026 models with Gold certification include features like modular cables and high-quality components.
Platinum Certification
Platinum-certified PSUs are even more efficient, reaching 89-92% efficiency at various loads. They are ideal for users seeking maximum energy savings, quieter operation, and longer lifespan. These units often include premium components and enhanced protections.
