| 1124339 | 2010-08-03 12:17:00 | Obviously a computer PSU was not designed with the intention of running car headlights in mind, but as far as I can see most of them should be able to provide the current required. Is there anything I'm missing or should this concept work just fine? (And of course I would merge all wires for both 12v and GND to prevent them overheating) |

| 1124340 | 2010-08-03 12:33:00 | Guess it would work fine. I think you turn a PSU on by shorting two wires together in the motherboard connector, don't know which though But still, I would probably use a cheapie before trying a flash new one |

| 1124342 | 2010-08-03 12:49:00 | forum.miata.net As long as your psu can supply 15-18 amps (four filaments) continuously, at 12vdc, don't see why not :2cents: (might get warm though). To start the PSU connect pin 14 (green) to any COMmon (black) wire on the 20 pin plug or pin 16 on the 24 pin. www.smpspowersupply.com |
