New 24V ATX style power supply powered board has been tested.
Seems like a few of you here might find this interesting.

This new board is a key part in completing the future BOM post for my 14" Z conversion on my RB2. https://plus.google.com/113930448883604105560/posts/ENXgHFEEnei
What do you mean by 24v ATX?
ATX power supplies (think computer) are typically 12V. This board is powered by a 24V ATX power supply.
The advantage is that the power supply drops the voltages to 5 and 3 instead of the board doing it. Really helps with heat dissipation problems and leaking voltage issues. Also allows direct heated bed pass through voltage supply through the board with firmware control.
Got any links? I can’t find anything online about 24v ATX supplies except for the low-current hack of pairing the +12v and -12v rails. Near as I can tell, if it’s a 24v PSU, it’s not ATX. I’m not an expert though.
It is not very common yet. Here is the link:

It is a true 24V ATX power supply. 550W. It is custom made for 24V powered 3D printers.
ATX does not specify 24V. Are you boosting the 12V rail to 24?
They are 2 X 24 V rails. See the second picture in the link for the readout. Not your standard ATX voltage but this is an ATX power supply. 24 +4 pin connector.
Huh. Did you custom order that, or hack it yourself? I think by “not very common yet” you mean “violates the ATX standard and will fry actual ATX devices”…?
Don’t get me wrong, it’s a cool idea and I am 100% supportive of 24v printers. I have often thought that it would be great if we had a 24v PSU with the voltage rails and remote power switch functions of ATX. Just seems dangerous to use the same connectors and call it ATX.
Ah, so it’s a modified ATX supply design, still using the same Molex 5566 connector, but with 24V where you’d typically see 12V.
This modified version is not an ATX supply as it does not adhere to ATX specifications.
@Thomas_Sanladerer I understand your point. How would you describe it? ATX “Style” power supply for 24V 3D printers?
@Ryan_Carlyle It was custom manufactured by an ATX power supply maker for use on 3D printers. I have three of them. I have a Kycon adapter plugged into one for use with an older style board. Regardless of what it should be called it is a great 24V power supply and very stable. By not common yet I mean… in the 3D printing world.
