Seasonic Launches 1600W Ruby-Certified PSU
💡A 1600W, 95.4%-efficient PSU could reduce power and heat in GPU-heavy AI workstations.
⚡ 30-Second TL;DR
What Changed
First 80 Plus Ruby-certified 115V ATX PSU
Why It Matters
Higher-efficiency power supplies can reduce electricity waste and heat in AI workstations or small inference servers. However, a single 1600W ATX PSU is more relevant to GPU workstations than large-scale data-center deployments.
What To Do Next
When sizing an AI workstation with high-end GPUs, compare the RX-1600's efficiency curve and connector support against your peak power draw.
Key Points
- •First 80 Plus Ruby-certified 115V ATX PSU
- •Provides 1600W of total power
- •Reaches up to 95.4% efficiency
- •Targets high-power workstations and infrastructure systems

🔑 Enhanced Key Takeaways
- •The 80 Plus Ruby certification was introduced by CLEAResult in April 2024, specifically designed for data center power supplies to meet the increasing power demands of AI and high-performance computing.
- •The Ruby standard for 115V ATX PSUs mandates specific efficiency levels: 85% at 5% load, 91% at 10% load, 93% at 20% load, 95% at 50% load, and 91% at 100% load, alongside a power factor of at least 0.95 at 20% load.
- •The Seasonic Prime Enterprise RX-1600 demonstrated an efficiency of 88.88% at 5% load during testing, significantly surpassing the 85% Ruby requirement for low-load scenarios.
- •The 80 Plus Ruby standard expands upon previous certifications by introducing a crucial 5% load test point, which is particularly relevant as systems often operate at low power draw for extended periods.
- •Seasonic has a historical track record of being a pioneer in 80 Plus certifications, having produced the first certified power supply in 2005 and the first 80 Plus Gold certified unit in 2008.

🛠️ Technical Deep Dive
- The 80 Plus Ruby certification introduces a new 5% load test point, which is critical for measuring efficiency during idle or very low power consumption states, an area less emphasized in previous top-tier certifications.
- For 115V ATX PSUs, the Ruby standard requires a power factor of at least 0.95 at 20% load.
- Achieving Ruby certification necessitates advancements across the entire power supply platform, including thermal design, component selection, and sophisticated switching control mechanisms.
- The Seasonic Prime Enterprise RX-1600 is built on the ATX 3.1 standard, ensuring compatibility with the latest high-power components.
- Seasonic's Prime series, to which the RX-1600 belongs, typically features Micro Tolerance Load Regulation (MTLR) of 0.5% or less, extended hold-up time exceeding 30ms, fully modular cabling, and utilizes premium components such as Japanese capacitors.
- In the Prime series, Seasonic engineers have implemented a design where the PSU back panel and the main PCB are connected via a copper plate instead of traditional cables, which helps reduce production errors and enhance output power quality.
