Hi guys,
So, the 12V 30A Power Supply on the Openbuilds site is out of stock and I was just wondering if the ATX 12V 29A Power supply from Printrbot would be fine to use?
Thanks for any help, Jason

Should be fine with any power supply that is 12V DC and at least 20A. If you aren't planning on using the heated bed, you could get away with a 15A PSU. Although that being said, I'm not sure how you would use an ATX power supply in this case, don't have much experience with them all I know is they have a ton of outputs. Alternatively, you can purchase a PSU that is nearly identical from RobotDigg. I haven't tested it myself but RobotDigg is used for a number of other components and they tend to make very high quality parts despite coming from chnia and being fairly cheap. www.robotdigg.com/product/547/12v+350w+Power+Supply

Hey Jason - Since you brought up the idea you are probably already aware, but there are tons of examples on converting ATX power supplies to 12V hobby use on the interweb. Just thought I would throw this up in case someone might not know about this. It is a great low-cost alternative (especially if you already have an old PSU laying around you are not using). These offer very clean power and are quite reliable. Here is a cool one that is a little more detailed than may be necessary, but just thought I would share. www.instructables.com/id/Convert-an-ATX-Power-Supply-Into-a-Regular-DC-Powe/?ALLSTEPSI like how they utilize the different voltages available for use. Just found another one... www.instructables.com/id/ATX--%3E-Lab-Bench-Power-Supply-Conversion/?ALLSTEPS I think I like this one better as it has some fuses installed. Safety First! Of course you could also just cut off and terminate the wires you don't need and just use the 12V wires and wire it up as per the Eclips3D design if this is the only thing it will be powering. Rock

That's funny! That is actually the video that I was thinking about earlier but just couldn't seem to find it. A very simple and straight forward way to use the atx psu. I have only seen a couple vids from Maker Geeks but this just reminded me that I liked them and will definately check out what else they have. Thanks for sharing!

I actually ordered that same power supply off amazon. Will post back if something is amiss.
