Zalman ZM300B-APS
300W ATX12V 1.3 Power Supply
Complies with Intel ATX12V ver 1.3. This power supply was
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.
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.
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.
When the temperature inside the power supply is 55°C or less,
the cooling fan will operate in 'Quiet' or 'Silent' mode.
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
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.
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).
