My newly built PC wont boot after installing the graphics card

My newly built PC won't boot after installing the graphics card (GTX 660). Once I remove the graphics card everything works fine. I'm using a 475 watt PSU so it should be able to power the card, What should i do now?

475w is cutting it a little bit close for a 660, what kind of unit is it? Cheap units often times won't even get close to their stated wattage which sounds exactly like whats happening here.

It's a Cooler Master Extreme 2. Is that a bad brand?

Yes, majority of Cooler Master PSU's are garbage and yours is one of them. Here are some real quality units that I would recommend.

So you're saying that my PSU isn't delivering enough wattage to power my Graphics card is that right?

Yes, there's no other way a GPU can keep a system from turning on.
