    I have been reading all the threads to get an idea of what works best but wanted to check with the forum that I am on the right track before I go to much further researching the wrong things.

    I am building a 2dof seat mover. (attached photos of build so far and a few more on my build thread) Car seat (fairly heavy from an Optima Kia) my weight of 90kg all sitting on a universal joint with shoulder mount height for gear attachments.

    Similar to Nick Moxley's build. I know over time some of these builds have changed (or psu failed) so wanted to check that what people started with a few years ago is still what works now.

    Is any one able to confirm the following will likely work together on this setup. I understand there are many variables but just a rough idea.

    Motor
    Worm drive Motor 12v 180 rpm 20nw (motion dynamics)


    Power supply
    HP 575W POWER SUPPLY FOR PROLIANT DL320S PS 600 PB B


    JKR x2

    Question 1. Is the power supply sufficient for these motors and are the motors powerful enough.

    Question 2. If the budget allows is their any recommendation on alternate psu that may may not be second hand/unknown history. PC psu from what I have ready here are not really up to the task?

    Thanks

    I have used the HP PSUs, but switched from second hand units to brand new ones when the latter came up on eBay. They are ok but led PSUs are pretty cheap and less sensitive to fluctuations, I have 3 of them as well but they were a bit big pyshically for my design criteria.

    Do use clip on ferrite cores on all leads.

    Yes the motors are powerful enough for a shoulder mount design. When unpowered they are easily back driven.

    Thanks noorbeast. I will keep an eye out on eBay. Do you have the name for a Google search on the led psu you mention. Space is not a massive issue for this build. Thanks mate.
