Hey, You should look at Amps fuse rating ?A
usually all 800 watts amps does not consider thier RMS power,it is just a peak power. There is a formyla to calculate AMPEREGE, volt X current.
12 x 60 = 720, So you need some thing like that.
but remember one thing an old Computer PSU are not as good as the latest ATX PSUs.
