Complies with Intel ATX12V ver 1.3
With the goal of enhancing the computing environment, all Zalman Tech products are noise-free. This product is a noise-free 300(400)W ATX (version 2.03) / ATX12V power supply supporting Intel Pentium 4 and AMD CPUs.

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.

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.

Certified with Safety Approval EMC Standards - UL, C-UL, CE, TUV, CB-NEMKO, FCC

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).
