Micronics ASTRO II GD 1650W 80PLUS Gold Full Modular ATX3.0

The Micronics ASTRO II GD 1650W 80PLUS Gold Full Modular ATX3.0 is a high-performance power supply unit (PSU) designed for demanding PC builds and enthusiasts. Released in October 2022, this PSU offers a robust and efficient power solution, ensuring reliable performance for even the most power-hungry components.

With a rated output of 1650W, the ASTRO II GD provides ample power for high-end gaming rigs, workstations, and servers. It features an 80 PLUS Gold certification, which guarantees high energy efficiency, reducing energy consumption and lowering electricity bills. The voltage regulation is impressively tight, with a variance of only ±0.3%, ensuring stable and consistent power delivery.

The power supply utilizes a +12V single rail design with a 100% availability of the +12V output, providing up to 137.5A. This design is ideal for modern GPUs and CPUs that demand substantial power. The PSU also incorporates an active PFC (Power Factor Correction) circuit with a power factor of 99%, improving the efficiency and reducing the amount of reactive power.

Cooling is managed by a single, large 135mm FDB (Fluid Dynamic Bearing) fan, which operates quietly and efficiently. The fan’s design and bearing type ensure long-lasting performance and minimal noise. The unit also features a fanless mode for silent operation under low loads and automatic fan speed control to adjust cooling based on the PSU’s temperature and load.

The Micronics ASTRO II GD is a fully modular power supply, allowing users to connect only the cables they need, which improves airflow and reduces cable clutter. It includes a comprehensive set of connectors: a 24-pin main power connector, two 8-pin (4+4) EPS connectors, two 16-pin (12+4) PCIe 12VHPWR connectors, six 8-pin (6+2) PCIe connectors, twelve SATA connectors, six 4-pin IDE connectors, and one FDD connector. This extensive connectivity ensures compatibility with a wide range of components and configurations.

Additional features include fanless mode for silent operation under low loads, automatic fan speed control, and power-saving functions like standby power consumption below 1W. The PSU supports a wide input voltage range (free voltage), making it suitable for use in different regions without the need for a voltage converter.

Internally, the ASTRO II GD is designed with 105°C capacitors for enhanced durability and reliability, DC to DC conversion for stable power delivery, and an LLC resonant converter for improved efficiency and reduced power loss.

For protection, the power supply includes a comprehensive set of safety features: over-voltage protection (OVP), under-voltage protection (UVP), over-current protection (OCP), over-power protection (OPP), over-temperature protection (OTP/OHP), short-circuit protection (SCP), surge and inrush protection (SIP), and no-load operation (NLO) protection. These features ensure the safety and longevity of both the PSU and the connected components.

The Micronics ASTRO II GD 1650W comes with a 10-year warranty, providing users with peace of mind and assurance of its long-term reliability.

In summary, the Micronics ASTRO II GD 1650W 80PLUS Gold Full Modular ATX3.0 is a powerful, efficient, and reliable power supply unit designed to meet the needs of high-performance PC builds. Its robust design, extensive connectivity, and comprehensive protection features make it an excellent choice for enthusiasts and professionals alike.
