if you want to find the least noisy power supplies then look towards modular video synthesis - virtually all lzx modules up til this point are very susceptible to noise and up to much higher frequencies (MHz instead of KHz) - you can literaly see the noise on the video output - small blocks appear that shouldn't be there for example
the PSUs that are generally recommended for video are the Doepfer PSU3 and the TipTop studio bus - and Malekko used to do one, but have discoontinued it I think
of the power supplies I have:
The PSU in the Mantis is very similar to the studio bus and works perfectly well for video
The Befaco Excalibus also appears to do a great job
Frequency Central PSUs introduce noise - for me - horrible - but are perfectly fine for audio
Haven't tried the meanwell in my Bastl Marton case for video - may give it a quick go next time I re-arrange things - which could be within the next couple of months
From all accounts the Intellijel ones are not suitable for video
Regarding outputs - I live in europe so don't bother with one - the only reason I would get one is if I needed balanced ouputs - which I don't - and I use an es8 as an audio interface anyway - current output patch is master out of tex-mix into streams for compression into 2 multiples - each one patched to es8 (usb to iphone), a unity mixer (to create a mono mix for sensory translator) and attenuators to go to speakers (so I can reduce the volume without impacting the audio reactivity)

Utility modules are the dull polish that makes the shiny modules actually shine!!!
