The year 2026 has seen significant advancements in the design and safety features of SFX power supplies. Among these, overcurrent and short-circuit protections have become critical for ensuring the longevity and safety of computer components. This article explores the top SFX power supplies in 2026 that excel in these protective features.
Understanding Overcurrent and Short-Circuit Protections
Overcurrent protection (OCP) prevents excessive current from damaging components by shutting down or limiting power when a threshold is exceeded. Short-circuit protection (SCP) detects unintended connections that cause a sudden surge of current, automatically shutting off power to prevent damage or fire hazards.
