Best cap series for power supplies?

[TahoeEd]

This post in the FAQ does a very good job outlining the best caps for a motherboard recap across various brands:

However, are there different caps that are betting suited for a power supply? Or, can that same list be transferred to a power supply recap? I have typically been using Nichicon HZ and HN, since they are available through Mouser in a variety of sizes. Are they the best choice for recapping a power supply, though?

I noticed that Nichicon lists PJ, PS, and TS for switching power supplies:

Thanks for any input, and a little education.

Re: Best cap series for power supplies?

It is my understanding the ultra low ESR caps that are ideal for the system board (MCZ, GA, etc) are not always the optimal choice for power supplies.

PX, ZL/ZLH, and similar seem to get the approval. There are also choices between aqueous and non-aqueous types, and the endurance numbers are important for PSU use.

I am also looking forward to the posts here, from those more in the known.

Re: Best cap series for power supplies?

I think power supply caps tend to heat up more than motherboard caps, and they don't require quite such low ESR. So I'd be hesitant to use the extremely low ESR caps in a PSU, because I think they tend not to be as resilient and aren't needed. There's undoubtedly some tradeoff that goes into manufacturing those things.
