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
