Abstract
The invention relates to a power supply device and a method for reducing energy consumption of the same. The power supply device is electrically connected with and drives a mainboard. The mainboard is triggered to output a power-on signal or a power-off signal to the power supply device. The power supply device is provided with a standby power supply module for modulating an external power and outputting a standby power. While receiving the power-on signal, the power supply device disables the standby power supply module and enables a main power supply module to convert the external power into a working power, and the working power replaces the standby power to be output into the mainboard. While receiving the power-off signal, the power supply device disables the main power supply module and enables the standby power supply module to output the standby power into the mainboard.
Description
Technical field
The present invention relates to a kind of power supply unit and reduce the method consumed energy, espespecially a kind of output by controlling stand-by electric is to reduce the power supply unit of power consumption and to reduce the method consumed energy.
Background technology
ATX(Advanced Technology Extended) be the motherboard specification the most generally used now, and the power supply unit implemented under ATX specification can't directly be connected with a starting switch of infosystem, it triggers indeed through the Ps_on signal that a motherboard transmits and just can start, and this power supply unit is not in time starting, normality supplies a stand-by electric (being commonly called as 5Vsb) to this motherboard, makes this motherboard have electric power at any time and enters the state of awaiting orders and starting.When this starting switch presses triggering by user, this motherboard exports Ps_on signal to this power supply unit immediately, make this power supply unit using this stand-by electric as startup power supply, and at least one power for operation required under completing this motherboard normal operation of startup output, and this power for operation of indication is namely if ATX is for 12V, 5V, the 3.3V etc. in electrical specification.
And from aforementioned, this power supply unit normality generally used now exports this stand-by electric, and this stand-by electric changes an external power output by a stand-by electric supplying module normality and obtains, this stand-by electric supplying module can't stop exporting this stand-by electric by forbidden energy because of the startup of this power supply unit.That is, as long as this power supply unit is connected with the external power of a normal supply, namely this stand-by electric supplying module can be made to continue this stand-by electric of conversion export, though so can guarantee that this motherboard or this power supply unit have electric power at any time and can normally start, but this stand-by electric supplying module will inevitably lossyly produce in the process of this external power of conversion, and after this power supply unit normally starts, the supply of this power for operation can meet the power consumption demand of this motherboard mostly, this stand-by electric is caused effectively not used, and be regarded as wasted energy.That is, this power supply unit now can't adjust the conversion output of this stand-by electric according to the power supply state of this power supply unit, and creates many unnecessary power consumptions.
Summary of the invention
Fundamental purpose of the present invention, is to overcome and commonly uses power supply unit normality supply stand-by electric and cause the problem of power wastage.
For reaching above-mentioned purpose, the invention provides a kind of method reducing power supply unit power consumption, be applied in a power supply unit, this power supply unit receives an external power and modulates this external power with a stand-by electric supplying module and exports stand-by electric to motherboard, this power supply unit comprises one and receives a starting-up signal from this motherboard and modulate with a main electric power supplying module open state that this external power exports a power for operation, and one receives an off signal from this motherboard and stops this main electric power supplying module to modulate the off-mode of this external power in this open state, the method comprising the steps of has:
