Did you recently connect the power supply to the motherboard? The reason I ask is that I have the same Corsair CX600. When I installed it, it was very hard to get the 24-pin connector to snap to the motherboard. You should have a definite click when it connects. The Power Supply not being connected correctly can cause the very problem you are having. I could not get mine to connect and decided to buy this StarTech.com 24 Pin ATX 2.01 Power Extension Cable - power extension cable - ATX24POWEXT - Power and Y Splitter Cables - CDW.com The white plastic on the extension is very slick and it fits on the Power Supply very easy and the other end just slides on the motherboard. It is well worth the money if you think this might be your problem

Maybe the connection isn't perfect and that is why it does not turn on.
It took so much force to push the power supply 24pin connector into the motherboard 24 pin female connector. Still didn't give me a good feeling that it went well even tho it seems to be connected.

The 2 pins that you see there dont seem to plug in. I tried and checked also. Only the 6 pins that are grouped together fit into the motherboard cpu port.

Hopefully it will work. Otherwise i might send the motherboard back and get refund .. choose another board. But i will keep the extension that i ordered because it might come in handy next time.
