IntelCop: Why is the power consumption still low when your computer is on standby?

The first thing to do the company every day is to open the computer, although now SSD popular, computer boot speed as long as a dozen seconds, but after the boot of yesterday’s software, documents need to be re-opened, can not do the effect of the office. So why is the power consumption of the computer still very high when on standby, so that we have to shut down in order to save power?

In general, desktop standby takes longer than it does. Reducing energy consumption during long standby periods is critical to reducing the overall energy consumption of your PC.

IntelCop: Why is the power consumption still low when your computer is on standby?

Intel Coproad: The current desktop power supply works by converting the ac power (AC) of the plug into the direct current (DC) required by the computer. This current conversion causes the most power loss when the computer is on standby and is the least energy efficient. So when the computer is on standby, the power consumption is still not low.

Ac-DC-TO-DC energy consumption efficiency is lower than that of DC-DC(DC-DC), so reducing the multiple DC output of the power supply to a single DC voltage output can improve energy efficiency, especially in standby.

In response, Intel created the ATX12VO standard and shared it publicly, a unified standard that helps PC manufacturers reduce standby power consumption on desktop systems.

Compared to the ATX12V, the ATX12VO literally becomes the standard of “only 12 volts” (“12V Only”). In fact, the ATX12VO is more than just a new power supply, the new ATX12VO standard will also require a redesign of the motherboard.

Currently, most power supplies use 12-, 3.3-and-5-volt power rails or voltage-generating circuits. The ATX12VO standard removes the 3.3 and 5-volt power rails from the power supply and changes the voltage from the motherboard.

As a result, the power supply outputs only 12 volts of DC voltage, and the two parts of the power supply and motherboard work together to improve the power supply’s energy efficiency.

The industry’s first ATX12VO motherboard is an ATX12VO motherboard for the 10th generation Intel Core S Series platform introduced by PC manufacturer ASRock. It reduces standby power by 27% compared to similar-featured motherboards and traditional ATX multi-rail power supplies.
