New 80 Plus Ruby PSU Certification Sets New Efficiency Standard for Data Centers

New 80 Plus Ruby PSU efficiency rating exceeds Titanium standard, coming to data centers

In brief: New, higher energy efficiency ratings have gradually emerged for top-tier power supply units (PSUs) over the years, and new workloads have encouraged standards to continue increasing. In response to the growing pressure from cloud computing, artificial intelligence, and other data-intensive applications, ClearResult has introduced its latest benchmark. ClearResult recently introduced 80 Plus Ruby, a new energy efficiency rating for PSUs that surpasses the current highest tier, Titanium. Initially, Ruby-rated PSUs will be used in data centers, though it's unclear when they will be available for consumer PCs These Ruby-rated PSUs could just as well be labeled 90 Plus, as they are required to maintain at least 90% energy efficiency across the entire power delivery system, even under a light 5% load at 230V, 277V, and 480V AC-DC, as well as 380V DC. This requirement, known as light loading, helps minimize energy waste in redundant or oversized data center configurations. Ruby PSUs must also achieve 91% efficiency at 10% load, 95% at 20% load, 96.5% at 50% load, and 92% at 100% load. The 80 Plus certification program is a voluntary rating system that indicates how efficiently a PSU converts electricity from an alternating current (AC) wall outlet to the direct current (DC) needed by a computer. The "80 Plus" label originally signified that certified units must achieve at least 80% efficiency at 20%, 50%, and 100% load levels. Launched in 2004, the 80 Plus system began with Bronze, Silver, and Gold ratings, which became common across PSUs at different price points. At 115V, the Gold rating requires 92% efficiency at 50% load and 87% at full load. Higher-grade PSUs now achieve Platinum and Titanium ratings. Platinum requires 92% efficiency at 50% load and 89% at 100% load (at 115V), while Titanium PSUs raise that bar to 94% and 90%, respectively.

Notable examples include SilverStone's 2,500W PSU, Super Flower's 2,800W unit, and Asus's 3,000W beast - all of which carry Platinum certifications. ClearResult emphasized the importance of advancing energy efficiency standards in anticipation of increasing data center power demands. The company estimates that data centers currently account for 0.4% of total U.S. electricity consumption, a figure that could rise to as much as 12% by 2028. This surge would likely be driven by the rapid growth of generative AI, known for its high energy requirements.

80 Plus Ruby: The aim for 96.5% Efficiency for Data Centers Power Supplies

The debut of the Ruby tier in the 80 Plus certification lineup marks a technical evolution for power supplies aimed at data centers and server farms. To earn a Ruby badge, a unit must hit at least 96.5 percent conversion efficiency at half load when fed 277 V or 480 V. It also needs to maintain 92 percent efficiency at full load. These criteria bump the bar above the previous Titanium level, offering a clearer benchmark for reducing energy waste across the most common operating ranges. Server energy usage has surged as cloud platforms and AI tasks place growing demands on data-center infrastructure. Analysts forecast that U.S. data-center electricity consumption could climb by between 6.7 and 12 percent by 2028. Recognizing that much of this power use happens even when servers are lightly loaded, the Ruby standard introduces a 5 percent-load requirement: units must still convert at least 90 percent of incoming voltage into usable output at this low threshold. This ensures that energy savings extend to idle or background operations -- critical for maintaining efficient power-usage effectiveness (PUE). Industry reactions have been swift. Delta Electronics has already secured Ruby approval for its 5 500 W redundant server supply, and other manufacturers are lining up to release compliant models. For IT gurus tasked with balancing performance, cost and sustainability, the Ruby certification provides a practical specification to guide procurement. By focusing on efficiency at multiple load levels, data centers can lower electricity bills, decrease cooling loads, and make progress toward carbon-reduction targets -- all by choosing the right power-supply hardware.

80 PLUS "Ruby" Certification Announced For Data Center: Efficiency Can Now Reach An Incredible 96.5%

As the requirement for high-efficiency PSUs booms, we now have the 80 PLUS Ruby standard, which aims to offer the highest efficiency among all the 80 Plus ratings. Power supplies come in various power efficiency ratings, which are often indicated through the 80 Plus certification. From 80 Plus to 80 Plus Titanium, the PSU manufacturers offer options to consumers and enterprises to enhance their systems' power efficiency. Up until now, the 80 Plus Titanium offered the highest possible efficiency on various loads, but this is now being topped by another rating called 80 Plus "Ruby". Achieving the highest standard of operations for data centers is critical as energy demand quickly grows and we are proud that the 80 PLUS Ruby certification is setting the example of what optimal data center energy efficiency can look like worldwide, - Divakar Jandhyala, CLEAResults Chief Product and Technology Officer CLEAResult, which is an energy transition and energy sustainability services provider in NA, announced this certification in March, which aims to offer up to a staggering 96.5% power efficiency on typical loads. On paper, it may not look too impressive coming from the Titanium certification, but that 0.5% higher efficiency can make a big difference when it comes to the data centers. The 80 Plus Titanium could offer up to 96% efficiency on 50% load, which is the best you could afford till now. The 80 Plus Ruby not only surpasses the Titanium certification at 50% load but also at 10%, 20%, and 100% with 91%, 95%, and a good 92% power efficiency. Interestingly, the 80 Plus Ruby-certified PSUs can achieve a staggering 90% efficiency even at 5% load. This will ensure incredible power savings at ultra-low loads and will be particularly helpful in scenarios where the servers don't need a lot of resources to execute smaller processes. It represents a next-level benchmark, providing the industry with a standard for both performance and energy usage. - Jason Boehlke, Senior Energy Sustainability Practice Manager, CLEAResult One of the first power supplies to bring this standard to Data Centers is from Delta Electronics, which is a Chinese PSU company. Delta released its 5,500W PSU for AI servers that can achieve a staggering 97.5% efficiency. Expect more such PSUs to be introduced soon, but it's unlikely that the 80 Plus Ruby certification will make it to the mainstream PSUs for the consumer market.
