Abstract
A system to provide an indication to a power supply unit that a computing device operably coupled to the power supply unit is idle. The system includes an interface including power rails to provide power from the power supply unit to the computing device and an idle control line to provide an indication from the computing device to the power supply unit that the computing device is idle.
Claims25
A system comprising:
- a power supply unit (PSU);
- a computing device to receive power from the PSU;
- and
- an interface to couple the PSU and the computing device, the computing device to provide, via the interface, an indication to the PSU that the computing device is in an idle state.
A power supply unit, comprising:
- a voltage converter to convert an alternating current to a direct current and to provide a first DC voltage on a first power line and a second DC voltage on a second DC power line;
- and
- an idle controller to receive an indication that a computing device operably coupled to the first power line is in an idle state and to configure the voltage converter to only provide the second DC voltage on the second DC power line.
A method comprising:
- receiving power from a power supply unit (PSU);
- providing the received power to a computing device;
- determining whether the computing device is in an idle state;
- and
- providing an idle signal to the PSU based on a determination that the computing device is in the idle state, the idle signal to include an indication that the computing device is in an idle state.
At least one machine readable medium comprising a plurality of instructions that in response to being executed by power supply unit (PSU) controller cause the PSU controller to:
- send a control signal to a converter of the PSU to include an indication to convert an alternating current to a direct current;
- provide a first DC voltage to a computing device;
- receive an indication that the computing device is in an idle state;
- and
- reduce a power consumption of the PSU based on receiving the indication that the computing device is in the idle state.
