Is the Corsair CX400 400W ok for a micro ATX motherboard. I'am not sure if you need a specific kind of power supply but I wanted to make that it would be ok.

depends on what else you are using in your computer...but it's probably fine
All the motherboard requires from the PSU is the 24 pin power connector and the 4 pin CPU power plug.. Every PSU will have that and so does the Corsair CX 400.. The concern should be over the components that you connect on the motherboard (like video card, processor) and their respective power draws.. For example, if you intent on using a powerful video card like the GTX 480, you would require a higher wattage rating PSU..
