SFX 3.1 Power Supplies: The Revolution in Small Form Factor Power
Building a powerful PC in a compact, small form factor (SFF) case has never been more popular—or more challenging. The space constraints of an SFF build demand a PSU that is not only compact but also capable of powering the most advanced, power-hungry components. Our range of SFX 3.1 power supplies is the definitive answer, delivering elite-level performance in a tiny footprint.
SFX + ATX 3.1: The Ultimate Combination
The SFX 3.1 standard combines the ultra-compact SFX form factor with the next-generation power delivery of the ATX 3.1 specification. This fusion allows you to build a no-compromise PC in a mini-ITX or other SFF chassis without sacrificing performance or safety.
Extreme Power Density: SFX 3.1 PSUs are engineered to pack massive wattage into their tiny chassis, with high-wattage models now available that can confidently power even an NVIDIA RTX 5090 or other high-end graphics cards.
The Secure 12V-2×6 Connector: Like their ATX 3.1 counterparts, SFX 3.1 power supplies feature the revised 12V-2×6 connector. This crucial upgrade provides a more secure and reliable connection to your GPU, addressing the issues of earlier standards and ensuring your system is protected from power-related risks.
Superior Transient Power Handling: The ATX 3.1 specification’s enhanced ability to handle sudden power spikes from modern GPUs is critical for SFF builds, which often have limited cooling. This ensures your system remains perfectly stable, preventing unexpected crashes and reboots under heavy load.
Fully Modular for a Clean Build: All of our high-end SFX 3.1 power supplies are fully modular. In a space-constrained case, this is non-negotiable. It allows you to use only the cables you need, dramatically reducing clutter and improving crucial internal airflow.
Choosing an SFX 3.1 power supply from our collection means you are getting a future-proof, high-performance unit that solves the unique challenges of small form factor building. It’s the essential component for an SFF rig that looks clean, runs cool, and delivers uncompromising power.
