Server PSU Based Radio Power Supply
A low cost, high current power supply for Amateur Radio utilising a Server PSU.
Designs are available at Github
Construction guide on the Github Wiki
Features
- Near 13.8VDC Output, 47 A (Exact specs to be determined)
- Various Fan Control Options.
- Distribution (2 Fused Anderson Powerpole connectors)
- Current Sharing / Parallelisation of 2 PSUs (2 boards required).
Tasks (Completed)
- Identify maximum voltage obtainable from supply.
- OVP cuts in at about 13.9v, however OVP protection will trip if a 1A load is suddenly attached by 13.75v.
- Modify PSU to boost voltage 12v->13.8v (or as close as possible)
- This is possible using a resistor between the 12v sense-return pin and ground. 260Ohm resistor suggested.
- PCB designed (See Github)
- Check EMI (Noise on outputs seems to be low, suggest using ferrites core on DC power leads)

Complications
- Original PSU was going to be a Dell POWEREDGE 2950 Redundant Power Supply however upon testing this supply, voltage would not rise above 12.2v and would drop to unusable voltages under load.
