Specifications: 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 the product..
Cooling Fan Speed in Relation to the Power Supply's Internal Temperature |
- 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).
- Strict DC Voltage Regulation & Low Output Ripple / Noise

Installation: Pretty straight forward. Mount the PSU in the space provided in your case. (DUH!) The hardest thing for me is the routing of the cables. I don’t like the sight of the power cables (or any cabling for that matter) just laying inside my case. It hinders airflow, and IMHO just looks bad. Luckily Zalman has made the cabling long enough so that you can pretty much hide the excess cable. Your case setup will determine your routing, so just look for places to tuck and hide the excess. I’m currently using the Chenming style case, so for me the ATX and extra P4 conectors are ran behind the PSU, and brought down to not interfere with the airflow around my CPU. All the power supply lines are run down the back of the case, and brought across the drives to be connected. All fans and lighting are connected at the bottom.
