This is an ongoing log of the standby power draw of various devices I own.
HP X576dw Printer
- Idle, ready to print (whirring): 25 W
- Idle, spun down: 10 W
- Standby: 5 W
- Sleep: 2 W
- Off: None
These figures are for a Wi-Fi connection. Ethernet and USB may vary.
HSU ULS-15 Subwoofer
- On (LED glowing green): 15 W
- Standby (LED glowing red): 15 W
- Off (LED glowing red): 15 W
Sadly, the amplifier draws full idle power whether the switch is in the on, auto, or off positions—the standby/off states merely mute the speaker and don’t conserve any power. As a workaround, I have the ULS-15 plugged into a smart power strip that also powers my A/V receiver and is set to turn off power to the subwoofer when the AVR is off.
PlayStation 4 (PS4) Console
On, at home screen:
- Idle: 80 W
In rest mode, based on which standby features are turned on:
- USB power: 9 W*
- Network: 4.5 W
- Network + USB power: 9 W
- Neither: 4.5 W
(*) Charging a controller increases power consumption by 4 watts.
Yamaha RX-A3000 A/V Receiver
Based on which standby features are turned on:
- Network + HDMI passthrough: 5.5 W
- Network: 5.5 W
- HDMI passthrough: 3.75 W
- Neither: None
