1500W should be plenty, but the card may not be getting enough power. On a much smaller system (3 drives, 1 3ware card), I had power problems. I used a 400W power supply and the +-5V rail was only delivering 3.9V. I kept losing drives. This was an 'expensive' Antec power supply. I switched to a budget 300W power supply just to see what would happen. The unit delivered a much cleaner ~4.8V. It's worked great ever since.
