i was wondering what made the prices so much different on these 3 power supplies.

With the Seasonics is it just the gold rating, or is there something big that i'm overlooking?

Both the Seasonic's are better than Antec. The 650w Seasonic is so much more because it is MODULAR and because of the 80GOLD rating. They are all solid PSUs, your pick.

All three are good PSUs. Obviously the Seasonics are better and more efficient, but I think that you would be pleased with any of them.
