Frequently Asked Questions

Is there a price difference between SFX power supplies and ATX power supplies?

Yes, in most cases, SFX power supplies are somewhat more expensive than ATX power supplies that have the same wattage and efficiency ratings. This is generally the case because of the more advanced engineering and manufacturing processes needed to cram all of the components into a smaller casing. Regardless, the price difference has been shrinking recently as more people demand smaller builds. Considering price, it is essential to look at what requirements your build has. For example, if you are building a small form factor PC, then an SFX power supply will fit better into the SFF design and provide additional space saving benefits, making the cost worth it.

Modular Cable Design for Easier System Customization

Modular Cable Design for Easier System Customization

Our SFX power supplies come with a modular cable design so you can plug in only the cables needed for your particular system setup. This helps reduce cable mess in your small form factor PC case allowing for better airflow and simplifying the entire installation process. When upgrading components or changing system requirements, adding or removing cables becomes a hassle when components are fixed. Likewise, the quality modular cables provided with the power supply boast sturdy high grade connectors, providing seamless and enduring connections which minimizes power interruptions.
Quiet Fan Operation for Low Noise Performance

Quiet Fan Operation for Low Noise Performance

Powered with a low noise fan, our SFX power supplies operate quietly throughout the entire power supply unit (PSU) operating range. Unlike most fans, it contains smart thermal control features that allow the fan’s speed to alter depending on the PSU’s internal temperature. While on low to medium loads, the fan stays at very low speeds or completely stops entirely providing almost complete silence. When the load and temperature rises, the fan increases in speed to maintain optimal cooling. This quiet operation is especially important for small form factor builds that can become more sensitive to noise as the components come closer together ensuring silence while working freely.
Comprehensive testing to guarantee dependable performance

Comprehensive testing to guarantee dependable performance

Each power supply unit (PSU) SFX model undergoes thorough testing, which includes burning in the unit at full load for 72 hours or more, factoring in voltage and temperature variation. This method of testing utilizes real-world conditions while attempting to emulate different temperature ranges—versatile enough to satisfy our benchmarks. These assessments ensure compliance with industry standards, System FX guarantees dependable power throughout the operational lifetime of the unit. Rest assured, with SFX models, you are receiving reliable products—refined through stringent measures—for your build.
