Xbox 360 Power Consumption: Watts & Kilowatts by Model (Slim/E vs. Original)

2 hrs/day gaming (Slim): 0.175 kW × 2 h × 30 days × $0.16 ≈ $1.68/month
24/7 standby: 0.010 kW × 24 h × 30 days × $0.16 ≈ $1.15/month

Power draw varies by model and activity. Here's the breakdown.

Power Draw by Model

Model	Active Gaming (Watts)	Standby (Watts)	Active (kW)	Standby (kW)
Xbox 360 Slim (2010+) / E	~175 W	~10 W	0.175 kW	0.010 kW
Original Xbox 360 (2005–2010)	~200 W	~15 W	0.200 kW	0.015 kW

Conversion: Kilowatts = Watts ÷ 1,000.

Actual draw fluctuates with game intensity, resolution, installed vs. disc, Kinect usage.
Power supply ratings (175 W for Slim/E, 203 W for Original) are maximum outputs, not constant draw.
Standby ("Instant On" / background downloads) draws 10–15 W continuously.

The Slim/E models are noticeably more efficient than the original "Fat" 360s.
