There is no such thing that I know about made specifically for computers. I have seen 12 VDC to 120 VAC units at just about any car or electronics shop.
...you'd be much better off just getting a switching PCI card. They run $15-20. Inverters are inefficient and get hot. The conversion kit is much more compact, and I'd seriously consider that if you're willing to spend the money, but otherwise something like a "Criticool Powerplant" (that's what mine was that I sold with my Eheim) will work just as well.
that criticool power plant is veryclose to what i saw and am looking for but the one i saw had a 4 pin molex on the pci card not one that goes outside, anyone?? whats a switching PCI card? i cant seem to find anything on it...
Criticool went out of business a few years ago which was why I didn't mention it to you. However, you might find a used one because a lot of people have since upgraded to 12v pumps.
im wondering if anyone has any idea where i can get the back part of the Innovatek Eheim HPPS Plus 12V Water Pump, wouldnt that fit onto the eheim 1046??
for some unknown reason i just want to get this eheim to work even tho i have a few ddc 3.2's and ddc plus's that i got for my shuttles...
Ask them to special order it for you. The Eheim design is utter reliability with silence. That should be a no-brainer as who wants to come home to a tank of dead fish.
