I have a Mach2 and a UPBV2.
I am powering the UPBV2 from the “through mount” 12v cable.
Also using the thru-mount USB.
Attached to the UPBV2 12v is a QHY268M, with filterwheel, and two dew heaters. I also use the UPBV2 “motor port” to power a focus motor.
No problems with this setup.
As for XT60 connector — I bought a bag of XT60 connectors off Amazon and made my own cable(s) at the exact length needed for my OTAs. The XT60s require soldering and shrinkwrap. Another way to build the cable is get 2 cables - one with XT60 and another with powerpoles; then cut the two and splice one of each to the other.
I don’t use the Pegasus110v power supply as I am mostly “remote” without power. So I use a Yeti1500x which has 12v power pole output and powers everything on the OTA via the mach2 “thru cable” and UPBV2. (The Yeti has a nice 110v inverter builtin , which I use to power the Mach2 (using the mach2 24v power brick), and also a 110v Mac Mini computer.)
The Yeti is a bit pricey, but it will power everything for a night of imaging with some buffer. And it is about the same size/weight as 1 deep cycle battery (but has something like 4x the capacity.)

I’ll gladly make one for you for just a few bucks and for whatever the shipping is. I’ve got a few extra XT60’s and a Powerpole crimping set up. Let me know how long you want it. 14ga is plenty HD enough. I run a PW (with a very large primary mirror heater and secondary mirror heater), a dew heater on the guidescope, camera cooler, OTA cooling fans, etc all thru an UPB. The Powerwerks power supply has never showed over 6A current draw even while slewing a maxxed out Mach 1.
Let me know if you’re interested.
Best,

Hi folks I have a few questions about power supply via the Mach2 I am thinking of getting a Pegasus Astro Ultimate Powebox (UPBv2), but wanting to attach it via my Mach2's internal cabling as opposed to a dangling cable. Essentially I am trying one of the example setups mentioned in the Mach2 manual page 23. What will get attached to the UPBv2 is a typical setup of cameras/filter wheel/maybe focuser/maybe dew heater.
- So this means that the UPBv2's PSU (12v/10A) with XT60 connector is not useful on its own. If anyone here uses the same setup, did you just chop off the XT60 connector from that PSU and install an Anderson Powerpole connector instead to re-utilize that PSU for powering the Mach2 internal? Though I think I would just prefer to get a new PSU and save this one if I ever want to re-sell the UPBv2.
- If not that PSU, what PSU do folks use? Any recommendations? I see AP lists this one from Powerwerx. But can I just get away with something simpler like this 12V 20.8A one instead since I don't think I would need a variable PSU? Are there any other readily available PSUs with Anderson Powerpoles that can supply 12v/10-20A which is the recommended input for UPBv2. So that I am not attaching those connectors myself.
- What is the wire gauge / ampere rating for the internal cabling in the Mach2? I think I read in another thread it can easily do 15amps, but did not see any upper limits or I missed it.
- Likewise what wire gauge should I use for this setup? The Mach2 manual recommends 14 gauge on page 21, but instead recommends 16-18 gauge on page 23 for this setup. I was going to go with 16 AWG since it has higher amp rating but in another thread someone mentioned that accessories might prefer 18 AWG. The distance of the UPBv2 from the dec axis will obviously be very small, so maybe 18AWG will suffice too since it can do 15-20 amps max in short distances. Though this will obviously be limited by the internal cabling of the Mach2 as well as the cabling of the PSU itself to the RA axis input.
- Since I will need a custom Anderson Powerpole to XT60 wire for connecting the UPBv2 from the dec axis, where does one get such a custom wire? Powerwerx doesn't seem to have this connector and the only place I could find it was from some random amazon seller.
Thanks!

You can source XT60 to Powerpole pigtails for cheap. That way you can leave the original power cable that comes with the UPB v2 alone.

Furthermore,
For short runs of wire above the mount, at the
scope, it is not important to have heavy gauge wire. A short piece of
lighter gage can carry as much current as a long piece of heavy gage.
For
wire leading up to the mount, from a power supply, it is best to use as
heavy a gage as possible, since that is where the voltage drop takes
place from supply to mount. You want to minimize that drop. So using 14
gage is probably the best on that end.

The internal wire of the Mach2 is 16 gauge. It's approximately 2 ft long.
