Simply put, a modular PSU allows the builder to attach (or detach) cables as they're needed. Traditional power supplies, on the other hand, have the cables attached permanently to the PSU. For your system you want about 550 watts and to be safe get a 650 watt psu.
To fully understand PSUs you gotta know what each rating is -
The basic 80 Plus rating means that the PSU is rated for at least 80% efficiency at 20% load, 50% load, and 100% load.
The 80 Plus Bronze rating means that the PSU is rated for at least 82% efficiency at 20% load, 85% at 50% load, and 82% at 100% load.
The 80 Plus Silver rating means that the PSU is rated for at least 85% efficiency at 20% load, 88% at 50% load, and 85% at 100% load.
The 80 Plus Gold rating meas that the PSU is rated for at least 87% efficiency at 20% load, 90% at 50% load, and 87% at 100% load.
The 80 Plus Platinum rating means that the PSU is rated for at least 90% efficiency at 20% load, 92% at 50% load, and 89% at 100% load.
And 80 Plus Titanium (i got nothing)
Now, that doesn't mean that the PSUs perform exactly at those numbers, but they are close enough, and of course you probably aren't going to use exactly 50% load or whatever, but it is close enough to give a good idea of what a PSU is capable of.
Here are some PSUs to fit your system.
Corsair PSUs are generally good and also Seasonic.
