In a nutshell, it has much higher quality internal components. For example, it has much better capacitors. All of this results in a power delivery that's much cleaner, quieter, and far more stable.
The 500W PSU recommendation is for peak-rated PSUs. The 450W Rosewill 450-M is a continuous-rated unit and its +12V capacity is 444W. The typical 500W peak-rated PSU will have a +12V capacity of about 360W at the most. So as you can see, having a +12V capacity of 444W is overkill and that means the PSU should always be dead silent.
So, you get a high-end modular PSU and all the power your computer will ever need for only $64.99 shipped. Don't worry about future upgrades because you have no intentions of going with two video cards, and that's the kind of upgrade that would make me worry about recommending a good quality-made 450W PSU.
