It depends on your use for it. If your want sparks then maybe a HV resistor to stop the caps in the tripler getting cooked (unless it has a resistor built in).
you mean a HV resistor in series between the flyback and the tripler? Interesting... I may google some stuff on HV resistors, and see what value they come in. Though, it may be difficult to determine the power rating needed.

Not quite. [flyback] I [tripler] I [resistor] I [output]
I'm sure you've discharged capacitors before, the caps in the tripler may not be designed to handle such a discharge. In regards to HV resistors, we'll assume you are looking at about 75kv. Put 20 470K 1W resistors in series, Then place said resistors in a plastic tube and fill the tube with melted candle wax. That will give you a 20W 10M resistor that should handle 100kv if you do it well.
75kv from the tripler? I might actually be surpirsed if I got such high voltages. Thanks for the advice though, I'll take a look at what that might do for me.
I've just now gotten 2 ATXs converted and almost have them ready to be powered up!
I am still thinking that there ought to be some fuse proctection in my setup somewhere.
I was thinking perhaps A fuse between the atx and the zvs would be a good idea, but the atxs are already regulated and protected for current overload. So far, I think I'm safe to run a zvs!

In hindsight I should have mentioned that in order to run ATX psus in series, the base PSU must be left grounded, while the others must be opened and the negative wire traces on the PSU disconnected from ground. Usually this is quite simple and only requires some electricians tape where the PCB grounds to the grounded metal case.
I can do that. Its usually a green wire that comes from the pcb, and ties to the chassis with a lock nut correct? It should be easy to get that wire disconnected and snipped off. This installation is to be permanent.
