[CQ-Contest] 12V 30A Switching Power supply recommendation?

[Anthony Willard]

Just throwing this out there, have you considered using server power supplies?

The linked ones above are rated at 750W, that's over 60 amps at 12v.  The link shows HP, but you can find supplies from other server makers, too.

These are rugged power supplies, designed for 24/7 load.  They are designed for high density environments and are well engineered for noise free operation.  (Can you imagine a server room or data center with RF noisy power supplies in dozens or hundreds of servers?!)

If you need more than 12v, like 13.8v, many variations of these supplies can be tweaked for >12v operation.  Anecdotally, some can be modded as high as 14v; but this is not all, so check a particular model and research options and possibilities.
If your needs call for stable power in a small form factor, maybe one of these can work for you.
* I use the ones linked above for my shack power, and for FD operation, and they have been trouble free.
