Modular PSU?

[Ragnaros]

What's the difference between a PSU that is modular and one that isn't? I've heard people say that they prefer PSUs that aren't modular but i have no idea what they mean. >_>

So you would say that Modulars are better? Both Tagan and Hiper have gold plated connectors, but the difference in price is amazing. Hiper PSUs are 580W and cost £62 but Tagan's best PSU, which also happens to be 580W, is over a hundred quid. :O There is another Tagan for 20 quid less that has 580W but it doesn't say if it has gold-plated connectors.

Either way, i guess that makes Hiper the best for modular PSUs or am i missing something?
