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.
CLEAResult Announces 80 PLUS Ruby Rating for PSUs to Allow Data Centers to Reach Better Efficiency
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.
