Check your console bottom to be sure it says PROPOW-3 (9V version).
 
How to be 100% sure you need the 9V power supply.  (See photos in photo-section)
Remove the cover. The power section is at the bottom left near the reset button. You should see a large coil and power regulator (looks like a power transister) If these parts are missing, you need a 5V Neo Geo Power Supply.
