Conclusion: IMPORTANT: Although the rating and final score mentioned in this conclusion are made to be as objective as possible, please be advised that every author perceives these factors differently at various points in time.
Pros: UEFI Introduces Graphical User Interface BIOS replacement, Integrated Atheros b/g/n WiFi, MemOK! Increases memory compatibility for bootup, ASUS EPU increases energy savings, NEC-D720200F1 SuperSpeed USB 3.0 controller, ASUS BT GO! Bluetooth adapter
Summary: Compared to the Zotac H67-ITX , the P8H67-I has a touch higher idle power consumption, but the difference is trivial compared to the >10W advantage the P8H67-I has on load. The UEFI even allows for undervolting which could potentially make the board even more energy efficient.
