    Question Would this DC-DC be good for car use?

    Hi guys I came across a DC-DC power supply, model# R100T1205-12, just wondering if this would work for a computer. It seems to have all the voltages that go into an ATX power cable except 3.3v.

    Would it work as a 12v regulator running before a power supply? Or are the 10amps to much?

    That model only kicks out 4A at 12v, not 10A. Use R100S1212 for a 12V 8A supply. Should be fine. The power supply will only draw what it needs - you can't push too many amps into anything?

    Well the Epia-5000 says it takes less than 1A on the 12v, and my HDD also takes less than 1A so I don't see why this wouldn't work as a powersupply??????? Other than the lack of 3.3.

    I think you hit the nail on the head there. Lack of 3.3 - could be a problem.

    And as a pre-regulator for one of those power supplies that don't regulate 12v, you'll need a lot more than 2A.

    I'm only interested in this unit because I can get it really cheap. The other models are insanely expensive. So wouldn't it work if I wired the 12 and 5 from this straight to the motherboard and somehow grab 3.3 from something else like ...... lets say one of those little regulated cig adapters? It does supply 4A on 12v and if I only draw 2-3 then it should be fine. This all going on the numbers in the manual for my Epia *crosses fingers*.

    Yep, it probably can be made to work. You'll also need some kind of power-good circuit wired up to make the mobo boot.

    by the time you add everything in you'll have a hacked together POS with little power and a lot of wasted time, buy something else, or kick yourself later
