The CEC's mandatory efficiency requirements for the use of external power supplies in consumer audio, video equipment, and appliances sold in California went into effect in December of 2004. With continual updates to the regulations, the next taking effect on January 1, 2007, these standards mandate minimum efficiency levels in active and no-load modes and maximum standby requirements.

Mark	Description	Performance Requirements
Mark	Description	Nameplate Power Output (P_no)	No-Load Power	Nameplate Power Output (P_no)	Average Active Efficiency
I	Used if none of the other criteria are met.
III	California: CEC Tier 1 standard January 1, 2007 (mandatory) - Laptop computers, mobile phones, printers, print servers, scanners, PDA, digital cameras. July 1st, 2007 - Wireline telephones and all other applications	0 to < 10W 10 to 250W	≤0.5W ≤0.75W	0 to 1W > 1 to 49W > 49 to 250W	≥0.49 x P_no ≥0.09 x L_n(P_no) + 0.49 >=0.84
IV	California: CEC Tier 2 standard July 1, 2008 (mandatory)	0 to < 10W 10 to 250W	≤0.5W ≤0.5W	0 to 1W > 1 to 51W > 51 to 250W	≥0.5 x P_no≥0.09 x L_n(P_no) + 0.5 ≥0.85
Where P_no is the Nameplate Output Power of the unit under test. L_n refers to the natural logarithm.
