Key Themes
Generation-Next Compatibility
The PSU is specifically made to satisfy the latest PC hardware standards, as evidenced by its ATX 3.1 and PCIe 5.1 support. “With two 12V-2×6 connectors, these PSUs are built to handle NVIDIA’s 50 series graphics cards and AI PCs with ease.” Compatibility with both present and future high-power components is thus guaranteed.
Dual Native 12V-2×6 Connectors
This set includes two connectors made especially to supply power to contemporary GPUs. One of the identified major performance features is “2 x 12V-2×6”.
Stability and Performance
High power excursion handling: “The power supply can support up to two times the total power through an output port that complies with Intel PSDG (Power Supply Design Guide) ATX 3.1.” power excursion and 3x GPU power excursion.” It is made to manage short-term power surges. This is essential for preserving system stability when using powerful GPUs that can consume a lot more power for short periods of time.
Semi-Digital Control
To regulate PFC and LLC, the PSU uses a semi-digital design with integrated circuits (IC). This allows for “more stable and efficient power output” and “significantly enhances accuracy” through dynamic power adjustments.
The 80 PLUS Gold Certification guarantees excellent energy efficiency by lowering heat production and power usage. Your power supply will use less energy and run more efficiently if you have the Gold certification, which stands out as a trustworthy standard for energy efficiency.
High-quality components are used for greater longevity and dependability. This power supply is constructed with 100% server-grade 105°C capacitors and cutting-edge CoolMOS and SiC SBD components for exceptional quality and dependable performance.
Acoustics and Thermal Design
Quiet Operation
Low noise levels are prioritized for a more comfortable user experience with quiet operation. This power supply is made to run quietly, producing noise levels as low as those of midnight, guaranteeing a peaceful computer environment free from interruptions.
Zero Fan Mode
To further cut down on noise, the fan can be turned off entirely in zero fan mode when there is little load. “The Zero fan mode ON, available to stop the fan’s operation when TDP is below 40% to help with energy saving and providing silence.”
Fluid Dynamic Bearing Fan
This 135mm fan uses a fluid dynamic bearing to increase its longevity and reduce noise.
Protection and Durability:
Comprehensive protective Mechanisms
“OCP, OTP, OPP, SCP, OVP, UVP, SIP, NLO” are some of the protective circuits that cover the system against different electrical problems.
Alloy Copper Connector Terminals
The connections’ usage of copper alloy improves safety in the event of significant current surges.
UL Certified Cables
Power cables with UL certification are safe and durable. The interior copper wires and external high-density braided cover of the power cables are UL approved for safety and durability.
Surge Protection
Increased adaptability for more unstable power situations is achieved by incorporating external voltage spike prevention. The external voltage spike protection makes this power supply appropriate for small data centers that need reliability and safety.
