PC PSU recommendation for NAOMI2 + NETDIMM + CF reader setup

[asra]

Hello

the thread titile says it all really but I'm looking for recommendations on a PC PSU that I can reliably use on mi setup:
-naomi 2
-netdimm
-capcom io
-bootleg CF reader

the idea is to power the Naomi+netdimm directly through an external PC PSU (I have mitsu's adapter ATX-2-Naomi Power Adapters)

I've been looking into this and it looks like there's solutions that get you half way there but I'm looking for a reliable solution.
More specifically I read even 700w PC PSUs are problematic with some netdimms.

if people have recommendations for specific models or specs please hit me up.

I'm based in europe so 220V.

thanks in advance.
