    Hi guys,

    Has anyone used computer power supplies to run their pixels?

    I've collected a few over the years when I've been upgrading my PC's - ranging from 600, 750 and 1000 watt PSU's just gathering dust. Hence, I thought I can re-purpose these for my setup.

    Admittedly, they are not the slim Meanwell form-factors, so I'll need to be creative with how they are mounted in the enclosures etc.

    Having said, they should be on par with power and performance to the Meanwell power supplies - but hoping to get some feedback from anyone who is using them.

    Generic PC power supplies aren't interesting because the power is split across multiple rails/voltages. Server power supplies are more interesting, I use a few 1200W 12v ones.

    I use computer power supplies for my non pixel display. I've opened one up and all the same voltage wire coming out are connected together inside anyway. I'd open it up, detach all thin wires used and solder a much thicker gauge cable.
    Using PC power supplies are good if you have different voltage pixels (12v and 5v).

    I'm using no more than 5 amps across 4 power supplies. The white box contains two power supplies that didn't have sufficient enclosures. https://drive.google.com/open?id=1DRXc1bm-V8FskTdgjEJV3X6_s4trj-eQ

    I am new to this hobby, but currently using a computer power supply for testing and learning. I find they make a good supply for the testing and learning as you get 12v, 5v and 3.3v for playing with different pixels, esp8266....

    I still have not decided what to use for my display, but am considering some salvaged HP server supplies. So many things to consider, and where to spend $$$ and what to make do with in the first year or two is something i have been thinking about.

    Thanks for the feedback Daryl....I may actually have some spare server power supplies kicking around, so I'll check them out :)
    Much appreciated.
