Compact Flex 1U PSU for SFF builds

This SMUGDESK MF500F is a 500W full-modular Flex 1U power supply designed for small-form-factor ITX cases such as the K39, K17, K30, A4, S3 and G5. It targets builders who need reliable, efficient power in a tight chassis for gaming, HTPC or industrial equipment. The 80 PLUS Gold rating means over 90% efficiency at typical loads.

Verify case clearance and cable needs

Before ordering, confirm your chassis accepts a Flex 1U unit and that the 24-pin mainboard, 8+4-pin CPU, dual 8-pin and dual 6-pin PCIe, SATA and 4-pin peripheral connectors match your components. Ensure the 90-264V AC input range suits your local mains supply. The full-modular design lets you attach only the cables your build requires.

Modular cabling aids airflow in tight spaces

Removing unused cables reduces clutter and improves airflow inside compact enclosures. A temperature-controlled fan balances cooling performance with low noise during continuous 24/7 operation. Built-in OVP, OCP, SCP and OTP protection circuits safeguard connected hardware against power anomalies, making this unit a dependable upgrade for space-constrained systems.
