    Yeah sure, I use a 230watt AT PS to power 3 case fans a 2 cpu fans...works great. You can even wire it up like I have with toggle switches to turn certain fans on or off( like the noisy ones)

    i am planning on doing the same thing with my new case as soon as i get it . im putting voltage control knobbs on each fan wired to the front of the case in a spare bay . seems like a good solution to bogging down your PS. Do you think it is a good way to get away with a smaller PS like a 300w for the cp and a 250w for fans?

    Sure, I've been running a ATX and AT PSU for a while (two ATX PSU's now) w/o probs, you might as well hook up your HD, CD-Rom and such to the AT PSU.

    Just use a relay to connect the two psus together. So when you press the power button on ur pc, the two psus get turned on at the same time.
