Seasonic PRIME Fanless PX 500W (PRIME-PX-500)
Silent power supply with passive cooling and efficiency 80 PLUS Platinum
Seasonic PRIME Fanless PX 500W is designed for systems where absolute silence is not just an advantage, but a mandatory requirement. This is a fanless ATX power supply unit that has no moving cooling elements at all. Passive heat dissipation eliminates any noise during operation and creates ideal conditions for audio studios, professional workstations, silent home PCs and office systems where comfort and concentration are key.
80 PLUS Platinum energy efficiency
PRIME Fanless PX is 80 PLUS Platinum certified and achieves up to 92% efficiency at 50% load. High efficiency reduces energy losses, minimizes heating of components and reduces the total energy consumption of the system. For the user, this means stable operation, less heat inside the case and energy savings during long-term operation.
True Fanless Design without compromises
Seasonic PRIME Fanless PX has no fan at all - cooling is realized solely due to effective heat dissipation. This approach not only ensures complete silence, but also increases the durability of the device, as it eliminates the wear and tear of mechanical components. The power supply maintains stable characteristics regardless of the duration of operation and load conditions.
Micro Tolerance Load Regulation for clean voltage
Thanks to Micro Tolerance Load Regulation technology, the deviation of the output voltage does not exceed 0.5%. This is critical for modern processors, video cards, and drives that are sensitive to power quality. Even with sudden changes in load, the system receives stable and predictable power, which increases reliability and protects components from stress modes.
500 W for efficient and balanced configurations
The power of 500 W is optimal for productive, yet energy-efficient systems — from workstations to quiet gaming PCs with a single graphics card. The power supply supports configurations with multiple graphics adapters, maintaining stability and efficiency. A wide input voltage range of 100-240 V provides versatility for use in various electrical networks.
Fully modular cabling system
PRIME Fanless PX is equipped with a fully modular cabling system. This allows you to use only the cables you really need, simplifying cable management and improving the internal organization of the case. Gold-plated connectors increase the reliability of contacts and reduce electrical losses, which is especially important for stable operation for many years.
Premium components and certification
Inside the power supply unit, a high-quality cell base with an MTBF resource of up to 100,000 hours is used. The model has a full set of international safety and compliance certificates, including RoHS, TUV, CE, EAC and others, which confirms compliance with modern quality and environmental standards.
Rational choice for silent systems
Seasonic PRIME Fanless PX 500W is a combination of absolute silence, high energy efficiency and stable power supply. It organically complements the flagship line of fanless power supplies from Seasonic and is aimed at users who want to build a reliable, quiet and durable system without compromise.
