Best power supply for 5-6 isolated connections?

What is your preference of a compact and isolated pedalboard PSU with 5-6 connections? I've been looking at the MXR M239 ISO brick which has five outs, one with 18V capability. So far this is my main contender, but I would love to hear what you all think.
 
the Cioks DC7 (or the Eventide Powermax) has basically solved it for me. It's definitely pricier, but I put it in the "buy once, cry once" category. I don't think I'll ever need another power supply.

Each output is not only isolated, but you can set the voltage for each individually (9/12/15/18v). Gives you a few options to run different dirt/fuzz at different voltages to coax out some other textures.

IF you need more outlets, you can get a 4 outlet or 8 outlet expander and run it off the DC7. For about the first year I had it just the DC7 was enough. I ended up adding a 4 to my main board for a total of 11 outlets. I'm usually running 9 or 10 pedals on my Metro20, and it's been flawless. I have extra outlets if I want to demo a pedal or two without tearing the rest of the board apart.

They also have adapters to combine outlets, or the Crux if you need to accomodate a particularly hungry pedal.
 
What's the difference between these? I see the price and company is the same.
I have the 1st gen PowerMax- it is basically a DC7 but without the "link" output to add later expansion supplies and sold for slightly cheaper. The PowerMax v2 (the current one) adds the link output back but takes the voltage selection off of a few of the outputs. Same with the Eventide PowerMini which is a slightly changed Cioks 4. Honestly I'm not sure why Cioks would make these slightly changed versions of their supplies when the original is only slightly more expensive and the alternate version doesn't add any features to justify existing.
 
"Best" for me is the Cioks DC7 for its high current capacity, quality build and voltage flexibility. I have one (actually the 1st gen Eventide PowerMax, but essentially a DC7) on my more power-hungry digital board. I also use a couple Truetone CS6 supplies and they have worked great for me too on smaller boards and each cost me (slightly used) less than half the cost of a used Cioks DC7. One cool aspect of the CS6 is that each output is capable of outputting more than it's rated current as long as the total for all pedals doesn't exceed the total for the whole supply. Means less specialized cables in some cases (I've run an HX Stomp off a single output many times without issues, though Truetone apparently no longer suggests that due to occasional issues with that amount of current draw).

My board requires vastly more power than that (Cioks DC10 and DC10 Link) but I have one of those mini iso's for my home recording area. Nothing but compliments as it's clean enough that I notice no noise recording.

If you're going to expand and have the room, definitely go Cioks, but if that MXR meets your needs I highly recommend it. It's perfect for my use case. Could be for yours as well. It's also light enough where velcro versus drilling holes is doable. Maybe dual lock but close enough.

All of this is powered off a Cioks DC7 and Crux Converter, and is dead silent. No issues at all. All of it works flawlessly.
No drilling, very simple mounts, sold separately of course. Cioks Grip & mini Grip (4 the Crux), 19.99 and 17.50 on top of the 339 I paid for the DC7 & Crux Converter. All you need is a phillips head screwdriver. Board is a Pedaltrain.

Not that anyone has mentioned Cioks gear or anything. 🤣
