  • Finally!....found a 12V DC/DC convertor for ATX PC's!!!

    After MUCH surfing I finally found it. http://www.keypower.com/DC_power/DX-250H.htm

    Keypower's got a 9V-18V DC/DC convertor for ATX systems. Checking this badboy out it appears it's got enough power for my Celeron 633 and periph's! Even has the "power good" line. The even bigger surprise..kinda..is they're in central New Jersey, USA! Sweet. When I find out on Monday how much they want I'll post it here, unless someone already knows and would like to share that info...

      Don't know yet. I figured they wouldn't be open on weekends but called them anyway. Yeah, they're closed today so we'll have to wait until Monday.

          Actually, I called Keypower in NJ and their price is $180 for the 250W DC/DC ATX model. I almost fell off my chair when she told me!

          However, if you think about buying a good power inverter and an ATX power supply, as I would need to, then you're in the same ballpark figure. The thing is though, I wonder if the parts inside have their markings...if anything goes on it I'd like to be able to replace it myself.

            Well, I broke down and bought the Keypower DC/DC converter.

            I gotta say first that the people in the South Plainfield office were pretty nice and answered all my questions both over the phone and when I went to pick it up. Construction looks and feels solid and there's a 2 year warranty. Sweet. They also gave me a little break on the price. Can't wait to hear.......or is that NOT hear?...this baby. Cheers!

                  I was looking for weeks on the Web and the Keypower one was the only one I found that was for (A) ATX, (B) ran on a wide enough voltage range for auto application, (C) put out enough power, and (D) was a good size for the auto application.

                    build one yourself...
                    can make a big difference in price!

                      I got this power supply too...about a day ago...and I'm wondering how you hook it up to the car battery? Does the ground go to chassis ground and the positive terminal on the battery to the power supply positive? Or do you have to do two wires (pos/neg) to the battery, AND one to the chassis ground?

                        Keep us informed of the keystone ATX dc-dc psu. I would like to know does it generate heat? Does it need a fan? and how big is it? I know the arise 865V doesn't have alot of power but the nice thing it after hours of running it is still cold to the touch.
