Universal Power Supply

  • 2500


The all new Universal PSU V3.0. Bigger and badder than ever, complete with a well illustrated build guide.

  • Fully compatible and optimized for the new Deluxe 4U and Deluxe 5U chassis to allow easy installation on the base, chassis front panel, or on riser panels
  • Can accomodate 35mm, 30mm and 25mm caps
  • Double sided 70um copper tracks
  • Added PI resistors for a total of 7 per side of the PSU
  • Each side is completely independent of the other providing separate grounding take off points
  • Grounding scheme at user's discretion (i.e. can be utilized for star grounding)
  • Ground vias available for joining on-board/local ground
  • On-board heatsinking for the diodes
  • Larger tracks whenever possible
  • Most inputs and outputs have larger vias to accommodate large wires
  • Input and output vias arranged to also accommodate Snap-On terminals
  • Output has larger vias for direct wire soldering to the board
  • Output has vias arranged to either accept Euroblock connectors or Snap-On terminals
  • Diode Section and Capacitor Section can be joined either by large diameter jumper wires or Fast-On connectors or direct soldering
  • Capacitor section can be stacked one on top of the other. Connections for quick parallel stacking are provided via Snap-On connectors or direct soldering.
  • Diode section can be snapped off from the Capacitor section (0.2mm V-Cut both sides)
  • Capacitor section can be snapped off lengthwise regardless if the Diode section is still attached or snapped off for more build flexibility (0.2mm V-Cut both sides)
  • Snapping is possible thanks to 0.2mm v-cuts on each side of the 1.6mm board.  It takes a lot of force to snap the board - enough so you won't ever snap it accidentally but not so much that you will have a hard time snapping it.
  • 80x80 mounting scheme on the Capacitor section for front panel chassis mounting
  • Extensively supports DA's mounting systems and bases
  • Options for Input snubbers (RC or RC + C) and options for output RC snubbers or bypass
If you have any questions please discuss them in the V3 Universal Power Supply Circuit Board thread.

Universal power supply

It was a pretty straight forward. If you follow the build guide and bom. I’ll be buying a couple for my future builds.

PSU board

these are very nice boards indeed...though I only bought them for the diode bridge section..which is rather neat as will be building my PSU on a discrete basis.....just a shame the Diode Bridge board was not sold separately...but it does at least break away from the PSU board....neatly..
.will keep PSU board for something my caps are coke can size...and will be fitted with copper bus bars....

Great pcb with many options

High quality pcb. I really appreciate the many options for connection.

Great looking item

Haven't used it yet, but look great, high quality.


love this place

Great Boards

As described. Works great. Easy build. Good solid quality boards. You will need a burly soldering iron as there are no reliefs around holes to the ground plane.


As usual, great service all around!


Board looks great. I understand that part kits are not your thing, but perhaps Mouser or Digi-key might pull together basic parts bags (actives, larger passives, specialized hardware) and DIY adds its needed markup . Would allow the time strapped hobbyists to get on with project. This not different from what you do for larger projects... Amps etc just for smaller items
