That's the highest wattage they go for the form factor I need.

So what's the best card I can put with a 3rd gen i3?

The best with a 3rd gen i5?

Seasonic PSUs can deliver upwards of 98% of their rated power on the 12 volt rail. This means that a 450 watt Seasonic PSU can deliver around 445 watts on the 12 volt rail before exceeding manufacturer specifications. Subtracting 100 watts for the platform, this still leaves 350 watts for whatever else you'd like. Even a GeForce GTX Titan would fit in there with headroom to spare.
