ATX Reference Design Exceeds 80 PLUS Silver Standards

The company’s latest open reference design for 255W ATX power supplies achieves an 85% efficiency level, which reportedly exceeds the 80 PLUS Silver, ENERGY STAR 5.0, and Climate Savers Computing Initiative Step 3 efficiency standards for desktop PC power supplies. The reference design delivers improved efficiency under real world operating conditions and in a configuration that allows for immediate production. Achieving a maximum efficiency of 90% at 50% load and at 230 and 240 Vac, it achieves greater than 88% efficiency at 50% load and 100 and 115 Vac. Efficiency is greater than 85% at 20% and 100% loads with 100, 115, 230, or 240 Vac. Efficiency measurements were obtained at the end of a 41-cm cable, ensuring the design is directly deployable in standard desktop-PC configurations. Additionally, the ATX reference design meets IEC 61000-3-2 power factor requirements for a power factor greater than 0.95 at 100, 115, 230, and 240 Vac.
