The Nikko Alpha 650 is a fan-cooled amplifier. It has independent toroidal power transformers for each channel. The power supply of each channel is filtered by two 15000 microfarad capacitors. The rail voltage is ±94 VDC.

The Alpha 650 is bridgeable. The rated output power (when bridged) is 650 Watts into 8 Ω.
