Power supply - Smart SE2 500W Modular (spr. 87%, Single Rail)

The THERMALTAKE Smart SE2 500W Modular power supply provides a compact, single-rail 12V design with modular cabling and an efficiency rating of approximately 87%. Designed for standard desktop and mid-tower builds, this unit delivers stable power for mainstream gaming systems and office PCs while reducing cable clutter through detachable cables. The PSU’s compact form factor simplifies installation in smaller cases and helps maintain airflow and internal organization.

Advantages

The Smart SE2 500W Modular combines a single-rail topology with modular connectors to offer consistent voltage delivery and simplified cable management. Its 87% efficiency reduces energy waste and heat output compared with lower-efficiency units, contributing to quieter and cooler system operation. The compact housing and standardized mounting make the unit compatible with a wide range of PC chassis, and modular leads allow installing only the cables you need for a cleaner interior.

Suitable for

• Mainstream gaming PCs with a single graphics card

Key specifications

• Rated output power: 500 watts
• Efficiency: approximately 87%
• Rail configuration: single +12V rail
• Cabling: modular cables for reduced clutter
• Form factor: standard ATX-compatible compact housing
• Protection features: built-in standard electrical protections (OVP, OCP, SCP, OPP)

How to use

Install the power supply into a compatible ATX chassis using the standard mounting points. Connect the 24-pin motherboard connector, required 4/8-pin CPU power connector, and the necessary PCIe power leads for a discrete graphics card if present. Attach only the modular cables needed for your components to maintain airflow and ease cable routing. Before powering on, double-check all connector seating and ensure the PSU switch is set to the correct mains voltage if applicable.

Recommendations

For reliable operation, pair the Smart SE2 500W Modular with systems that draw within the unit’s continuous power rating and avoid heavy multi-GPU or extreme overclocking configurations. Keep ventilation clear and periodically inspect modular cable connections for secure seating. Use a quality surge protector or an uninterruptible power supply (UPS) where mains stability is a concern.
