Product Description

With the goal of enhancing the computing environment, all Zalman Tech products are noise-free. This product is a noise-free 400W ATX (version 2.03)/ATX12V power supply supporting Intel Pentium 4 and AMD CPUs.

Key Features

  • Realizing a Noise-Free Computing Environment (CNPS) with Auto Control Cooling Fan
    By implementing heat-sensor circuitry that controls the cooling fan's speed (rpm) in relation to the temperature within the power supply, emanating noise has been greatly reduced. The graph below shows the CNPS characteristics of our product.

    [Noise Level(dB) Changes In relations to Power Supply's Internal Temperature]
    * When the temperature inside the power supply is 55Deg C or less, the cooling fan will operate in 'Quiet' or 'Silent' mode.

    * CNPS (Computer Noise Prevention System) refers to a system that reduces a conventional computer's noise (30dB or more) to an inaudible level (20dB or less).

  • Complies with Intel ATX12V ver 1.3
    This is the latest product in our power supply line-up, designed to comply with Intel ATX12V Ver. 1.3. S-ATA power connectors supporting S-ATA Ver. 1.0 compliant hard disk drives are provided as standard.

  • Simplifying Source Input - Free Voltage
    Unlike products with Passive PFC, where you have to set the operating voltage (115VAC / 230VAC) with a manual switch, this product can be used with any normal AC input source ranging from 100VAC to 240VAC.

  • Improving Power Factor & Eliminating Harmonics through Active PFC
    By implementing Active PFC, the power factor (PF) is improved from 75% (Passive PFC) to 94% (at full load), while harmful harmonic frequencies are reduced below regulatory requirements.

  • Supplies Stable Power to Intel Pentium 4
    By including a ATX12V 2x2 (4-pin) 12V power connector and an auxiliary 5-pin power connector, this product can provide stable power to Intel Pentium 4 CPUs, which need 6A of current from each power rail.

  • High Efficiency Power Supply
    Designed with a high switching frequency and low power-loss circuitry, the efficiency of this product exceeds 75% (at full load).
