## Long description

PRIME Fanless TX 700 W is a fully passive power supply unit designed for silent PC operation. With a maximum output of 700 W and 80 PLUS Titanium certification, it delivers high energy efficiency (94 % at 50 % load) and stable power for high-performance systems. The fanless design removes any audible fan noise by using passive heat dissipation, while fully modular cables and long cable lengths provide flexible cable management in the computer case.
Advantages
The fanless construction ensures completely silent operation without compromise on power delivery, and the 80 PLUS Titanium rating provides excellent efficiency that reduces energy consumption. Precision micro tolerance load regulation keeps voltages within a tight range (under 0.5 %), resulting in clean, stable output suitable for sensitive components. High-quality internal components and a modular cable design simplify installation and improve airflow inside the chassis.
Suitable for
Silent home or office PC builds
High-performance workstations and content-creation systems
Audio production or recording rigs where noise must be minimized
Compact or elegant cases that benefit from neat cable management

How to use
Install the Seasonic PRIME Fanless TX 700 W into a compatible ATX-compatible PSU bay following standard safety precautions: disconnect mains power before installation, secure the unit in the case, and connect the 20+4 pin ATX cable to the motherboard. Use the modular cables supplied to connect PCIe, SATA and peripheral devices as required. Ensure adequate case ventilation even with passive cooling to allow heat dissipation through the chassis and avoid placing the system in an enclosed, poorly ventilated space.
Usage recommendations
For reliable long-term operation, operate the unit within its rated input voltage (100–240 V) and avoid sustained loads at or near maximum output. Maintain case airflow and keep dust levels low to preserve passive cooling efficiency; periodic internal cleaning and correct cable routing will help ensure stable performance.
