Z-MACHINE Extreme Power Supplies Contents and Features

Solid Capacitors for Reinforced Stability
The Z-Machine PSUs are supplied with solid capacitors which have a longer lifespan and lower Equivalent Series Resistance (ESR) compared with electrolytic capacitors. They have been incorporated for maximum reduction of output ripple noise and ultra stable operation.

Heat-pipe Installed for Maximum Cooling Performance and Ultra Quiet Operation
An ultra high performance heat-pipe incorporated on the power supply's main rectifiers enables high load operation even at low RPM for a dramatic reduction in noise levels.

80PLUS BRONZE Certified High Efficiency Design
These power supplies have been certified 80PLUS Bronze with 82% minimum / 88% maximum efficiency (230VAC, Typical Load). They incorporating a high switching frequency and low power-loss circuitry design, which guarantees higher efficiency compared to uncertified products. 80PLUS is an energy efficiency certification program administered by Ecos Consulting of the U.S.A.

Flexible Modular Cables
Cables from a power supply can impede airflow, therefore Zalman have supplied slim and flexible modular cables. This simplified cable management aids optimal airflow through the computer enclosure for increased cooling performance.

Four Independent +12VDC Rails
Four +12VDC rails supply power independently to the CPU, VGA, motherboard, and peripherals for stable operation of core components.

Ultra Quiet 140mm Fan
An ultra quiet two Ball-Bearing blue LED cooling fan increases airflow while minimising noise for a superb ultra quiet computing environment.

Wafer Bridge for Reinforced Cooling Performance
Unlike conventional modular PSUs that utilise bulky wires to connect the main and modular circuit boards, a compact wafer is utilised, enhancing internal airflow and cooling performance.

Multiple Safety Features for the Highest Level of Safety
Over-Voltage Protection, Over-Current Protection, Short-Circuit Protection, Under-Voltage Protection, and Over-Temperature Protection features protect the system from potential electrical hazards.
