Introduction
Traditional ATX power supplies have been the go-to choice for PC builders for many years. However, in recent times,
smaller form factors such as SFX (Small Form Factor) and TFX (Thin Form Factor) have gained immense popularity and
revolutionized the PC building landscape. This blog post delves into the rise of SFX and TFX form factors and explores
how they provide an exciting alternative to traditional ATX power supplies.
Whether you are a PC enthusiast, a gamer, or simply looking to build a compact system without compromising on
performance, understanding the advantages of the SFX and TFX form factors will undoubtedly broaden your options and
inspire you to explore new possibilities in PC builds.
SFX Form Factor
SFX power supplies have taken the market by storm due to their compact size and excellent power delivery. Designed
specifically for small form factor cases, SFX power supplies have a reduced footprint, making them ideal for building
portable, space-efficient systems. With their unique dimensions and modular cabling options, SFX power supplies offer
versatility and allow for efficient cable management, ensuring optimal airflow in tight spaces.
Going beyond their small size, SFX power supplies have made significant advancements in power efficiency and
performance. Top-tier manufacturers now offer SFX power supplies with high-wattage options, allowing users to power
even the most demanding components. The increased power output does not compromise efficiency levels, as SFX power
supplies adhere to rigorous 80 Plus certification standards, ensuring energy efficiency and reducing electricity costs.
TFX Form Factor
TFX power supplies, although less popular than their SFX counterparts, offer their own unique advantages for certain
PC build scenarios. TFX power supplies are designed specifically for slim or low-profile cases, making them an
excellent choice for compact desktop systems. These power supplies are narrower than SFX power supplies and can fit
into even smaller enclosures, providing the freedom to build a powerful PC without compromising on size constraints.
TFX power supplies also come in various wattage options, making them suitable for a range of system requirements.
Despite their smaller form factor, TFX power supplies are designed to deliver reliable power and maintain high
efficiency levels. Their compact size allows for better airflow and ventilation, preventing overheating and ensuring
stable performance.
Comparison: ATX vs. SFX vs. TFX
| Form Factor | Size (W x H x D) | Main Application | Power Output Range |
|---|---|---|---|
| ATX | 150mm x 86mm x 140mm | Standard desktop towers | 450W to 1600W |
| SFX | 125mm x 63.5mm x 100mm | Small form factor cases | 450W to 850W |
| TFX | 85mm x 70mm x 175mm | Slim or low-profile cases | 250W to 400W |
