need to put in a 400 watt Power supply. I have a cougar rs 400. I put it in, connect the cables and the unit wont power on. all this is so I can use my new geforce gtx 650 ti.

did you connect both the 24-pin power connector, and the 4-pin cpu power connector? also check the on/off switch on the back of the psu itself. it could also be a bad psu.

I've double checked them. they are connecting solid. can a power supply be incompatible with a motherboard? Or do you think it is a bad unit?

well if its all connected properly, id say its bad. reconnect your old psu and make sure it boots.
