Alimentatore FSP Hydro PTM PRO 850W ATX ATX2.52 nero

The FSP HYDRO PTM PRO 850W is an ATX power supply unit with 80 PLUS Platinum certification designed for high-performance PC builds. It delivers up to 850 W of continuous power with high conversion efficiency and includes a 20+4 pin ATX motherboard connector plus CPU, PCIe, Molex and SATA cables. The unit features an active cooling system with a 135 mm fan and a semi-fanless eco mode that keeps the fan off until system load exceeds 30%. A proprietary conformal coating protects the PSU from dust, humidity and stains, allowing reliable operation in environments with up to 95% relative humidity. Fully modular black ribbon cables simplify cable management for cleaner builds.

Advantages

The HYDRO PTM PRO provides 80 PLUS Platinum efficiency for lower power loss and reduced heat generation, alongside a durable conformal coating that enhances component longevity in humid or dusty conditions. The semi-fanless eco mode reduces noise at low loads, and the user-accessible switch lets you enable or disable this mode easily. Fully modular black ribbon cables improve airflow and aesthetics in custom builds.

Suitable for

• High-performance gaming PCs and workstations
• Custom builds focused on clean cable management and aesthetics
• Systems requiring reliable operation in humid or dusty environments
• Users seeking quiet operation at low to moderate loads

How to use

Install the PSU into a compatible ATX case following standard safety procedures: disconnect mains power, mount the unit in the PSU bay, and connect the 20+4 pin ATX cable to the motherboard. Attach CPU and PCIe power connectors to the appropriate components, and use Molex/SATA cables for drives and peripherals. Use the eco mode switch located beside the main power switch to enable or disable semi-fanless operation depending on your noise and cooling preferences.

Recommendations

Operate the PSU within the specified input voltage range (100–240 V AC) and keep case airflow unobstructed for optimal cooling. Although the conformal coating increases tolerance to humidity and dust, avoid prolonged exposure to extreme conditions. Regularly check cable connections and secure modular cables to maintain good airflow and system stability.
