Wide Input Voltage Support for Global Use

This power supply supports a wide AC input range of 90–264V, ensuring stable operation in both domestic and international power environments.
The rated input range is 100–240V, and even at lower input voltages of 90–99V, the unit can still deliver up to 765W of output power.

It supports 47–63Hz input frequency, with a maximum input current of 12A at 100V and 6A at 240V, making it suitable for high-load systems.

High Efficiency and Low Standby Power

Designed for high energy efficiency, the power supply achieves:

• ≥87% efficiency at 20% load

• ≥90% efficiency at 50% load

• ≥87% efficiency at 100% load

The unit also complies with 2013 ErP standby efficiency standards, featuring an advanced standby mode where the main converter is switched off while the +5VSB rail remains active.
Standby power consumption is kept below 0.45W, reducing energy waste when the system is powered down.

Strong and Stable Power Output

The power supply delivers stable multi-rail output designed for demanding systems:

• +12V rail: up to 70A (840W)

• +3.3V / +5V rails: up to 20A each

• –12V: 0.3A

• +5VSB: 3.0A

The maximum continuous output power is 850W, with peak power support of up to 935W, ensuring reliable operation during sudden load spikes.

Excellent Voltage Regulation and Low Noise

All output rails are tightly regulated to ensure system stability:

• Voltage regulation within ±3% on major rails

• Load regulation within ±2%

• Ripple and noise levels as low as 40–60mV

Even under cross-load conditions, output voltages remain within specified limits, providing clean and stable power to sensitive components.

Reliable Hold-Up Time and Fast Transient Response

• Hold-up time: minimum 16ms at full load

• Handles rapid load changes (step loads) with voltage deviation kept within ±5%

Power-on and power-off overshoot is controlled to less than 10% of nominal voltage, protecting connected hardware.

Advanced Control and Signal Stability

The power supply features precise control and monitoring signals for system integration:

• PS-ON control signal (TTL compatible, open collector)

• PWR_OK signal with accurate timing and low noise

• Stable signal behavior ensures reliable motherboard communication

These features make the unit suitable for high-performance PCs, workstations, and industrial applications.

Output Protection

This power supply is equipped with multiple protection mechanisms to ensure safe and reliable operation under all conditions.
 

Over Power Protection (OPP)

When the total output power reaches 150% of the rated capacity, the power supply will shut down automatically and enter latch-off protection until the fault condition is cleared.
 

Over Voltage Protection (OVP)

Each output rail is monitored independently. If the voltage exceeds the specified threshold, the unit shuts down and enters latch-off mode.

• +3.3V: 4.3V

• +5V: 7.0V

• +12V: 15.6V

• +5VSB: 8.0V
   

Short Circuit Protection (SCP)

• A short circuit within Group 1 outputs will shut down all Group 1 rails.

• A short circuit in Group 2 will shut down both Group 1 and Group 2 outputs.
   

Over Current Protection (OCP)

Current is limited to safe levels to prevent damage.
The +3.3V, +5V, and +12V rails require AC line reset or PS_ON reset to recover, while the +5VSB rail automatically recovers once the fault is removed.

Over Temperature Protection (OTP)

An internal temperature sensor shuts down the power supply if a critical temperature is reached.
This typically occurs due to cooling fan failure or operation beyond thermal limits.
 

No-Load Protection

Disconnecting all DC output loads will not cause damage or hazardous conditions.
In some cases, the power supply may shut down safely.
 

Reset After Shutdown

• For output fault latch-off conditions, normal operation resumes only after the fault is removed and PS_ON# is toggled LOW again.

• For +5VSB fault conditions, the unit recovers only after the fault is cleared and AC power is cycled (minimum off time: 3 seconds).

Cooling System

The cooling fan draws air from the DC output side and exhausts it through the AC inlet side.
The fan is dedicated solely to internal PSU cooling and does not provide system airflow.
