Zalman ZM750-ARX power supply unit 750 W 20+4 pin ATX ATX Black

The Zalman ZM750-ARX 750 W power supply unit delivers stable power for desktop PCs with a single +12V rail, active PFC and robust protection features. Built with high-quality Japanese 105°C capacitors and a powerful DC-DC module, this black 80 PLUS Platinum PSU is engineered for efficient, reliable operation. It accepts 100–240 V AC (50–60 Hz) input and includes standard motherboard and PCIe cables; a 135 mm smart fan provides active cooling while keeping noise low.

Advantages

High-quality 105°C capacitors from Japan ensure stability under high temperature, frequency and current conditions. The built-in Active PFC circuit improves power factor and overall efficiency (rated 94%). A single +12V DC rail design provides a stable voltage supply for modern components. Heavy-duty secondary protection ICs protect against over-current, over-power, over-voltage, under-voltage, over-temperature and short circuits. The modular cable design helps tidy cables and improve airflow inside the case, while the ultra-quiet 135 mm fan with smart control balances cooling and noise.

Suitable for

• Gaming desktops and high-performance PCs requiring up to 750 W
• Workstations with multiple drives and add-in cards
• PC builds that prioritize efficiency and quiet cooling (80 PLUS Platinum)

How to use

Install the Zalman ZM750-ARX into a compatible PC case, secure it with screws and connect the 20+4 pin ATX motherboard power cable plus any required PCIe and peripheral modular cables. Ensure the AC input is within 100–240 V and the system is powered off while connecting. After installation, power on the system and verify that the PSU fan operates and that connected components receive stable power. Use the modular cables as needed to maintain tidy routing and sufficient airflow.

Recommendations

Place the unit in a well-ventilated case, route modular cables to avoid obstructing airflow, and keep dust filters clean to maintain cooling efficiency and prolong component life.
