Console Current ConsumptionThese values were measured on NTSC consoles using a 9V benchtop power supply. These values are averages because the actual current consumption is dynamic - though according to my experiments they don't appear to vary much.
| Unit | Avg (mA) | Peak (mA) | Notes | | Model 1 HD Graphics | 700 | 700 | Measured with and without a game inserted (Sonic 2), didn't seem to make a difference. | | Model 1 Sega CD | 500 | 1000 | Peak occurs right after booting. The Sega CD does not power up if a Genesis cartridge is inserted. | | Model 2 Sega CD | 500 | 1000 | Peak occurs right after booting. The Sega CD does not power up if a Genesis cartridge is inserted. | | Model 2 Genesis | 300 | 300 | Measured with and without a game inserted (Sonic 2), didn't seem to make a difference. | | 32X with 32X game | 350 | 350 | Measured with Doom | | 32X with Genesis game | 200 | 200 | Measured with Sonic 2 |
Game Cart Current ConsumptionThese values were measured on an NTSC Model 2 Genesis. These values are averages because the actual current consumption of cartridges is dynamic.
| Game | Avg (mA) | | Sonic The Hedgehog 3 | 13.2 | | Sonic The Hedgehog 3 and Knuckles | 11.9 | | Super Street Fighter 2 | 19.1 | | Virtua Racing | 120.4 | | Mega Everdrive | 133.1 (160+ while loading) | | Power Base Mini + Double Dragon | 6.9 | | Power Base FM + Double Dragon | 48.6 |
Power Supply Connector Type
| Unit | Connector Type | Polarity | | Model 1 Genesis | 2.1mm ID x 5.5mm OD | Center negative | | Model 1 Sega CD | 2.1mm ID x 5.5mm OD | Center negative | | Model 2 Sega CD | 2.1mm ID x 5.5mm OD | Center negative | | Model 2 Genesis | EIAJ-03 (1.7mm ID x 4.75mm OD)* | Center positive | | 32X | EIAJ-03 (1.7mm ID x 4.75mm OD)* | Center positive |
*Some distributors will list the Model 2 Genesis and 32X power supply connector as 1.7mm ID x 4.8mm OD |
