This is how much power my onkyo m508 consumes. Recently, I started having trouble getting it to come out of protection mode (orange to green lights). I had the power cord plugged into the onkyo preamp's switched power supply which is rated at 700 watts MAX. I've had it like this for at least ten years. Anyhow, the amp started acting normal once I plugged it in straight to the wall outlet. I'm beginning to think the preamp's switched outlet was starving it for power? However, I have no idea how much is 1,200 VA in watts. Thanks
