Propel your innovation with high-efficiency and cost-effective power supply solutions

Today’s communications and networking devices require power supplies that include digital control, low standby power and a high level of component integration for maximum efficiency. With Flex Sketch-to-Scale® solutions, you can optimize the performance of your power supply solutions for distributed power architectures by collaborating with Flex early in the design process to create products that meet time-critical or cost-sensitive needs.

From custom to highly scalable system solutions

We have dedicated Design Centers with specialized engineering teams that focus on cloud industries including server, storage and networking. Our custom product solutions are developed to exceed market needs for availability, efficiency, power density, cost and performance. Our engineers collaborate early with customers to develop their next-generation Distributed Power Architectures (DPA) in a smart, effective process.

In addition to custom solutions, we also design and manufacture scalable power supply solutions that improve the operational efficiencies of advanced data center, IT information and communications networks. Flex Coldwatt® products provide a complete on-board system solution for cloud, storage and server applications. Coldwatt® products address customer challenges while delivering superior quality, cost, performance and support at scale.
