I was reading about ATX motherboards and it said.
------------------------------------------------------------------------------ a..
a.. The momentary button on the front of the case that powers on the system is supposed to be connected to the motherboard. Unlike AT-style systems, it isn't directly connected to the power supply. Because the ATX motherboard is not physically disconnected from the P/S by the power switch, the motherboard can enter power down mode and be brought back up in a short amount of time. The main shutoff switch is almost always in the back of the power supply, although this feature is becoming more and more scarce with newer units. But holding down the front power switch for a few seconds will also shut off the machine (assuming things are setup that way in the BIOS). Some BIOSes allow an ATX momentary switch to act like an AT power switch and immediately shut off the computer. But the ATX power supply still needs to be attached to the motherboard and not directly to the On/Off switch.

I don't understand that but after I put a new powersupply in my computer what they call a momentary button doesn't have to be pushed anymore when I turn the computer on like before. Before I had to turn the power on at the surge suppressor and then hit the button on the front of the computer. Now just turning on the power at the surge suppressor starts the computer running.
Since I think the computer is running hotter with this PS I'm thinking of getting a different one. I saw a 400 watt with two fans on sale today. Does a 400 run hotter, is that why it has 2 fans? Am I going from bad to worse? <G>
