Mini ITX/Flex ATX 500W Fully Modular Power Supply - Compact SFF PSU

In this review the compact Mini ITX/Flex ATX 500W fully modular power supply is assessed for small form factor builds, POS and AIO systems. The bottom line: it is a focused solution for builders who need a full range 90-264V input and a truly compact, fully modular layout that fits tight enclosures. The review found the unit delivers solid 500W maximum power on a +12V rail while offering modular cables to reduce clutter, but prospective buyers should be aware that fan noise and heat behavior vary by system.

Key Features

• Fully modular design: Allows only the cables needed to be installed, simplifying tight small form factor and Flex ATX layouts and improving airflow.
• Full range Active PFC: Accepts 90-264V AC which makes it suitable for a wide range of locations and unstable mains conditions.
• Compact dimensions: At roughly 160mm x 73.66mm x 35.5mm it fits Mini-ITX and Flex ATX cases and some 1U enclosures where space is limited.
• Robust protections: Built-in OVP, OLP, OCP, OTP and SCP protect connected components and improve reliability in varied workloads.
• Versatile connector set: Includes 20+4 main, split 8pin (4+4) CPU option, two 6+2 PCIE, two SATA and two Molex for broad compatibility with small builds and peripherals.
• Forced ventilation: A 40mm double ball bearing fan provides active cooling in confined spaces where passive cooling is insufficient.

Who It's For

This power supply is well suited to enthusiasts building compact Mini-ITX or Flex ATX systems, point-of-sale or all-in-one systems, and small servers that need a fully modular cable layout and a reliable 500W output from a single +12V-dominant rail. The full range 90-264V input also makes it useful for users in locations with variable mains voltage.

It is less suitable for noise-sensitive desktop users who demand whisper-quiet operation, since customer feedback shows inconsistent fan noise levels. Users planning high-end multi-GPU setups beyond the unit's two 6+2 PCIE connectors should consider higher wattage units with more connectors.

Pros & Cons

Pros

• Compact, fully modular layout reduces cable clutter and eases installation in small cases.
• Full range Active PFC supports wide AC input, making it flexible for different mains environments.
• Comprehensive protection features provide safety for components under stress.
• Good connector mix for typical SFF builds, including split 24pin and 8pin options.

Cons

• Fan noise is inconsistent across units: some users report it loud under load while others find it quiet.
• Limited to 500W which constrains very high power GPU or multi-device configurations.

Our Verdict

For compact system builders and POS/AIO integrators who need a fully modular PSU with full range input and a compact footprint, this 500W unit is a practical, value-oriented choice. It delivers the necessary connectors and protections for most small form factor projects, though buyers should accept the 500W ceiling and possible variance in fan noise when evaluating suitability.

Frequently Asked Questions

Will this power supply power on by just plugging into the outlet?
Answer. No, the unit will not power on simply by connecting the power cord; ensure all internal power cables are correctly connected to the motherboard and devices.

Can the CPU 8pin and 24pin connectors become 4pin and 20pin?
Answer. Yes, the 8pin CPU connector splits to 4+4 and the 24pin motherboard connector splits to 20+4 by pushing one half down and the other half up as described in the manual.

Is the cooling adequate for small enclosures?
Answer. The 40mm double ball bearing fan provides forced ventilation suited to tight spaces, but thermal and noise results vary by case airflow and workload.
