ATX 3.1 and PCIe 5.1 Ready
This PSU is fully ATX 3.1 compatible. It ushers in tighter voltage and current regulation for next-gen hardware. The included 16-pin PCIe cables deliver up to 600 watts to PCIe 5.1 graphics cards. This readiness ensures your build is prepared for future graphics cards. It supports the latest standards for robust performance.
Gold-Plated High-Performance Copper Pins
The PCIe connectors feature gold-plated copper pins. This upgrade ensures cooler operation and improved power delivery efficiency. It significantly reduces 12V-2×6 connector temperatures by up to 10°C. This promotes optimal stability for demanding graphics cards. The improved contact also enhances durability during insertion and removal.
Protective PCB Coating
A protective conformal coating envelops the circuit board. This layer helps protect against short-circuits caused by moisture, dust, or debris. It enhances durability and stability. This added protection ensures reliable performance throughout the PSU’s lifespan. It is a key feature for long-term reliability.
80 PLUS Platinum Efficiency
The ASUS Pro WS Platinum uses low-ESR Japanese server-grade capacitors. This enables 80 PLUS Platinum certification. It guarantees 89% efficiency at 100% load and 92% efficiency at 50% load. This high efficiency results in less heat and reduced fan noise. Consequently, you gain increased reliability for your workstation.
Advanced Cooling System
Effective cooling is vital for a 1600W unit. This PSU uses large extruded aluminum heatsinks. They have up to twice the volume of standard designs. This dissipates heat more effectively. It helps extend the lifespan of internal components.
Dual-Ball Fan Bearings
The fan uses dual-ball bearing technology. These bearings boast a lifespan of up to 80,000 hours. They last up to twice as long as sleeve bearings. This ensures long-lasting, reliable cooling with minimal noise. It is a superior choice for continuous professional use.
Etched Cables and DIY Design
The PSU features etched cables made from pliable premium materials. They are flexible for easy installation. These cables operate at temperatures 50°C lower than the safety limit. The CPU and PCIe power connectors are DIY-friendly. They feature distinct clips and unique colour schemes. This simplifies installation and ensures secure connections.
