I currently have a Bronze rated PSU in my system. I've never really understood the difference out of the bunch. It seems gold and plat are much more expensive than bronze and silver. There has to be a reason.

It has to do with the efficiency of the power conversion. The higher the rating, the less energy is lost (some in the form of heat) in the conversion process. The benefits to you is lower energy cost to run your rig, and lower cost of cooling. It adds up over the life of an always-on PC.

The reason they're more expensive is because they're usually made of higher quality components which means it will have less chance to catch on fire than a cheap 750w psu ( i saw one for 20$ and alot of people ended up with it burning up after barely 5 minutes ) and have higher efficency than a bronze rated power supply
If i'm correct that's the only difference

What is 80 PLUS Efficiency and what level of efficiency do I need?

The 80 PLUSĀ® performance specification requires power supplies to be 80% or greater energy efficient at 10%, 20%, 50% and 100% of rated loads with a true power factor of 0.9 or greater. This makes an 80 PLUS certified power supply substantially more efficient than typical power supplies that offer below 80% efficiency.
