Frequently Asked Questions

What is 80 PLUS Titanium efficiency?

80 PLUS Titanium is the highest efficiency tier in the 80 PLUS certification program, achieving over 96% efficiency at 50% load with 230V input. This minimizes wasted energy as heat, reducing power costs and cooling requirements in data centers.

What is the difference between 230V and 115V PSUs?

230V PSUs are optimized for international and data center power infrastructure (typically 200-240V). They achieve higher efficiency at 230V input. Verify your facility's power infrastructure before ordering.

Is hot-swap supported without a redundant PSU?

Hot-swap PSU replacement requires a second PSU installed in the server to maintain power during replacement. Without a redundant PSU, the server must be powered down for PSU replacement.

The Lenovo 4P57A82019 delivers 750W of 80 PLUS Titanium-efficiency hot-swap power at 230V — a Gen2 ThinkSystem PSU purpose-built for high-availability, energy-efficient enterprise server deployments.
