High Power, High Efficiency - Delta New 120 kW Power Shelf Powers Up AI Servers

Diverse websites, various social media platforms, compelling videos and countless mobile / PC games… all these online services that permeate our lives are driven by networking and data center servers. With the recent pop-ups of chatbots and art generators, AI generative content brings a new wave of demand for AI servers, resulting in the blooming of ultra-high power supply systems. Having cooperated with several tech giants for decades, Delta observed the AI trend and developed the 120 kW power shelf with 24 power supplies inside for higher energy conservation.

AI generative content requires constant training and data learning to produce more accurate responses. This results in data center expansion and the higher power consumption of servers, elevating overall electricity costs. To reduce the unnecessary energy waste of servers, it’s important to heighten power conversion efficiency and cut electricity distribution loss, which is the strength of Delta server power supplies.

Delta has been collaborating with tech giants to provide customized and premium server power supplies for decades. As more and more companies started to integrate AI into their cloud services for consumers, they demand servers with higher performance and require power systems with higher output and efficiency. To satisfy customer needs, Delta launched the 120 kW power shelf, which consists of twenty-four 5 kW power supplies and boasts an impressive 97.5% power conversion efficiency to reduce unnecessary waste for AI servers.

The power shelf can also be customized into a 2N (two independent, mirrored power distribution systems, each encompassing twelve 5 kW power supplies) redundant power system with 60kW power output. During operation, both systems deliver power output at 50% load. When one system fails or any abnormalities (peak loads, spikes, or more) occur, the other will perform full-load mode to ensure the stable operation of AI servers. In addition, this power shelf conforms to the CANbus communication protocol to safely manage and control the power usage of AI servers — another way to reduce energy loss.

Based on years of experience and success in the market, Delta developed the 120kW power shelf and 5kW power supply with self-drafting specifications and design that went ahead of the market. The power self is now adopted by some world-class companies, and Delta is expecting to launch more advanced, high-power and energy-efficient server powers for AI fields in the near future.
