With the focus now shifting towards making more energy-efficient products, motherboard manufacturers such as ASUS have come up with technologies to keep power consumption (and heat output) down. Read on to find out more about the ASUS EPU as we put the ASUS P5E3 Premium to the test.

With the focus now shifting towards making more energy-efficient products, motherboard manufacturers such as ASUS and Gigabyte have come up with technologies to keep power consumption (and heat output) down. ASUS names their technology the Energy Processing Unit (EPU) while Gigabyte calls theirs the Dynamic Energy Saver (DES).

According to ASUS, the "ASUS EPU utilizes innovative technology to digitally monitor and fine-tune the CPU power supply with improved VR responses in heavy or light loadings. Working together with AI Gear 3+, it automatically provides power for higher performance or improves efficiency by 50% when the PC is running low intensity applications – helping you attain the best possible power efficiency and energy savings of up to 80.23% to help save the environment".

In the next few pages or so, we will be sharing with you our findings on EPU. First and foremost, the EPU functionality is not enabled by default. EPU functionality is tied with ASUS AI Gear 3+ power management software. AI Gear 3+ is part of ASUS’ AI Suite and the suite needs to be installed first before we can start playing with EPU.
