FSP FlexGURU PRO 500W Flex ATX 80 Plus Gold Non-Modular Power Supply – FSP500-50FDB

Uncompromised Power for Small Form Factor Builds

The FSP FlexGURU PRO 500W is expertly engineered to deliver reliable, high-density power for modern compact systems. Designed in the highly versatile Flex ATX form factor, this powerhouse is the perfect foundation for Small Form Factor (SFF) PCs, Mini ITX builds, 1U IPCs, Edge Computing hardware, and Network Attached Storage (NAS) arrays. By integrating a universal fix bracket directly out of the box, FSP ensures seamless installation and superior compatibility across a vast array of specialized enclosures.

80 PLUS Gold Certified Efficiency

Efficiency is paramount in tightly constrained chassis environments. The FlexGURU PRO boasts an esteemed 80 PLUS Gold certification, guaranteeing up to 90% power efficiency under typical loads. This ultra-efficient power conversion drastically reduces excess heat output and lowers energy consumption. As a result, users benefit from reduced operating costs, quieter operation, and significantly enhanced long-term system stability, keeping critical components functioning perfectly even under heavy workloads.

Premium Japanese Components and Single +12V Rail

Internal build quality is where the FlexGURU PRO truly shines. FSP utilizes premium Japanese electrolytic main capacitors to ensure precise voltage regulation and unmatched, continuous 24/7 reliability. This premium componentry is paired with a robust single +12V rail architecture, designed to provide tightly regulated voltage output and consistent power distribution. This setup safely and effectively handles sudden power spikes, effortlessly supporting power-hungry components during demanding applications without risking system resets or hardware degradation.

Advanced Thermal Management

Cooling in small form factor cases is notoriously challenging, but the FlexGURU PRO tackles it head-on. It is equipped with a highly durable 40mm 2-ball bearing fan complemented by intelligent fan speed control. This dynamic thermal management system actively monitors the power supply’s temperature, adjusting fan RPMs to deliver excellent cooling exactly when needed while remaining whisper-quiet during idle or low-load scenarios.

Clean Routing and Comprehensive Security

To accommodate the limited routing space typical of SFF builds, this non-modular unit features flexible, all-black round cabling. Unlike rigid standard cables, these round cables are easily routed through cramped chassis interiors, minimizing clutter and maximizing internal airflow for a clean, professional look. Safety is also prioritized, incorporating a comprehensive suite of industrial-level protections including Under Voltage Protection (UVP), Over Voltage Protection (OVP), Short Circuit Protection (SCP), Over Power Protection (OPP), and Over Temperature Protection (OTP), giving you absolute peace of mind for your valuable hardware.
