Zalman's new Acrux II Platinum 1200 W power supply unit (PSU) is positioning itself as a premium choice for high-end systems, particularly those requiring substantial wattage. The PSU is designed to handle the rigorous demands of next-generation hardware, including GPUs that push the boundaries of performance.
Key among its features is compliance with the Intel ATX 3.1 specification, which includes support for PCIe 5.1 and a native 12 V-2 x6 connector tailored for modern GPUs like the Radeon RX 9070 XT. This connector is critical for delivering stable power to high-wattage graphics cards, a necessity in today's competitive gaming and content creation landscape.
The Acrux II Platinum 1200 W PSU stands out with its efficiency ratings. It achieves up to 94% peak efficiency, earning it an 80 Plus Platinum certification. Additionally, it carries Cybenetics ETA Titanium efficiency and LAMBDA A+ noise certifications, ensuring both performance and quiet operation. These certifications are a testament to Zalman's commitment to delivering high-quality power solutions that balance efficiency with reliability.
Under the hood, the PSU features advanced power management technologies such as Active Power Factor Correction (APFC) and an LLC resonant converter. It operates on a single +12V rail DC-DC topology, which is known for its stability and efficiency. The use of Japanese 105°C capacitors further enhances its longevity and durability.
Cooling is handled by a 120 mm fluid dynamic bearing (FDB) fan with automatic speed control. This fan is designed to minimize noise while maintaining optimal thermal performance. A dedicated silent mode switch allows the fan to remain off at loads below 30%, providing a near-silent experience during lighter workloads.
The PSU is built to handle up to 200% transient power excursions for short durations (100μs), as required by ATX 3.1 guidelines. This capability ensures that it can deliver stable power even during sudden spikes in demand, a crucial feature for high-performance systems.
Zalman has also announced two smaller variants within the Acrux II series: the 1000 W and 850 W models. Both retain the 80 Plus Platinum certification, indicating that Zalman is offering a range of options to cater to different system requirements. The 1200 W model measures 140 × 150 × 86 mm in ATX format and is rated for a 100,000-hour Mean Time Between Failures (MTBF), reflecting its robust build quality.
Despite its impressive specifications, details regarding availability and pricing are yet to be announced. This leaves potential buyers in anticipation, eager to get their hands on what promises to be a high-performance power supply unit. For now, the Acrux II Platinum 1200 W PSU is a strong contender in the market for those seeking a reliable and efficient power solution for their next-generation systems.
