Re: Difference between Non-modular and modular PSU?
Modular PC's allow disconnecting of extra power cables that you don't need. It allows for better wire management because you only plug in the cables into the components/PSU that you actually need.
Non-modular is just a regular PSU: it has all the connections attached to it and are non-removable.
As for if you should get one or not... that's entirely up to you really. Like I said, they're better for wire management, which can help make the inside of your PC look cleaner, as well as help with cooling. You can still do this with a non-modular PC however, it just takes a little more work routing cables/hiding extras.
