It's not all in just the wattage output values, you also need to take into consideration 12A- outputs, connectors supported, etc. and PSUs that low in overall wattage generally can't support anything too powerful. Haven't been in hardware for a while so I may be out of the loop, but for reference, I had a similar problem with a 450W PSU not being able to power a GTX650 which locked up my motherboard... Can't imagine a 400W would fare better with a stronger card like the one you're eying.
