I think it just depends on the topology a little bit.

Even if it's a new PSU, if it uses an oldschool half-bridge design (which I know a lot of older CWT-built Antecs did), chances are you could probably get away with KMG or other GP 105C caps, simply because the switching frequency will likely be relatively low. Of course, there is a little bit more to it than that. (For example, the PSU transformer ratios can be designed to output higher voltage pulses with narrower width to get more "oomph" out of the switching transistors. This will put higher stress on the output caps and inductors. So that's one example where even a relatively low switching frequency PSU may benefit from low ESR caps. But even in those cases, GP caps with enough capacitance and adequate ripple current rating for the circuit should still handle the stress OK.)
