Advanced Dynamic Energy Saver

Gigabyte first launched their full range of Dynamic Energy Saver motherboards beginning with the P35-based series, and later included the X38 and X48 motherboards. Dynamic Energy Saver, or DES, allows you to receive unparalleled power savings of up to 70% and up to 20% improved power efficiency with the simple click of a button. Back as a new "Advanced" edition, the GA-EP45T-EXTREME allows even greater control and power savings.

"With more than one year of intensive design and testing, Gigabyte's Dynamic Energy Saver represents a truly amazing revolution in motherboard development," said Johnson Lin, CEO of Gigabyte United. "With one little click, users are able to take advantage of up to 70% CPU power savings without sacrificing computing performance. Imagine the potential for power savings on a global scale if every motherboard in the world was able to provide similar power savings."

Featuring an advanced proprietary software and hardware design, including high quality components from Intersil, Gigabyte Dynamic Energy Saver is a unique technology that provides exceptional power savings and improved power efficiency. The unique multi-gear power phase design of Gigabyte's Dynamic Energy Saver allows for the most efficient switching of power phases depending on CPU workload. When the CPU workload is light or at idle, the Dynamic Energy Saver downshifts gears and only allows the minimum required power phases needed to accomplish the task to operate. By turning off the power phases that are not needed, Gigabyte's Dynamic Energy Saver is able to dramatically save power, up to 70% compared to traditional motherboards, that would normally have been wasted. As soon as the workload increases, Dynamic Energy Saver recognizes that more power is needed and is able to shift into higher gear, turning on power phases as they are needed.


Unlike traditional power designs that keep all power phases active at all times no matter what the loading, Gigabyte's Dynamic Energy Saver features multiple gears, allowing the CPU to maintain optimum power efficiency from light all the way to heavy loading. In a traditional power phase design, each gear needs to operate at less than optimum efficiency, causing gaps in power efficiency. With the ability to switch on and off gears before they start to loose efficiency, Gigabyte's Dynamic Energy Saver is able to provide up to 20% improved power efficiency.

Dynamic Energy Saver User Interface Gigabyte's user-friendly Dynamic Energy Saver interface allows users to turn on and off the power saving features with a simple click of the Dynamic Energy Saver button. Not only can users see real-time CPU power consumption in Watts, but once Dynamic Energy Saver is enabled, users can also see how much power they are actually saving. In Meter Mode, Gigabyte Dynamic Energy Saver shows how much power users have saved in a set period of time. Like a trip odometer in a car, users are able to reset the power savings meter to zero. In Total Mode, users are able to see how much total power savings they have accumulated since activating Dynamic Energy Saver for the first time. Even if the Dynamic Energy Saver functionality is turned off, the total amount of power saved will be recorded until re-activated, when total power savings will resume recording power savings.

Gigabyte's Dynamic Energy Saver technology also delivers additional power savings with its Dynamic CPU Voltage Control. Adjust the CPU voltage according to power saving needs; Level 1 for Normal Power Savings, Level 2 for Advanced Power Savings, and Level 3 for Extreme Power Savings. Gigabyte's Dynamic Frequency Control (CPU Throttling) allows for additional system power savings with a simple 1-click on/off button.

Unique Dynamic Energy Saver Hardware Design
Gigabyte Dynamic Energy Saver enabled motherboards feature an LED display located directly on the motherboard, allowing users to see the dynamic gear shifting in real-time. As each gear is activated, a color-coded LED representing the gear lights up.

Gigabyte Dynamic Energy Saver + Intel 45nm CPU = Unmatched Energy Efficiency
Gigabyte Dynamic Energy Saver motherboards paired with Intel 45nm CPUs deliver the very best platform for multitasking, multimedia and high performance gaming, all while consuming very little power. By combining the improved performance-per-watt and optimized power savings of the Intel 45nm CPUs with the Ultra Durable, Ultra Cool and Ultra Energy Efficient performance of Gigabyte's Dynamic Energy Saver motherboards, users will be able to experience a new world of energy efficient computing.

Benefits of Gigabyte Dynamic Energy Saver
Not only does Gigabyte Dynamic Energy Saver help users save money on electricity costs, but Dynamic Energy Saver enabled motherboards also help to reduce the impact everyday computing has on the environment. Less power consumption means less energy is needed to be produced from coal burning power plants. This cuts down on carbon dioxide output, a byproduct of burning fossil fuels for electricity and a known component of greenhouse gasses.

Today it is more important than ever to help conserve and protect our environment. That is why Gigabyte has taken the lead to develop responsible computing technologies that have as little impact on the environment as possible. In addition to Dynamic Energy Saver, Gigabyte has removed lead and other hazardous materials from their products, helping to create a greener computing future.
