@Mastero Can you tell me if this design comes in a "complete" kit?
It seems I just can't get the right parts over here in Holland to build your design.
It has to be ordered and the prices are very high of the parts.

The PCB was design for TO-220 type. You should get LM2678T instead
LM2678SD has 14 pins vs 7 pins on LM2678T.
The answer is NO.

Mastero,
Have you found some time to check spikes on your LM2678 output ?
I'm pretty sure your mobo won't last a long time with a LM2678 standard design.
Regards

I'm about to build the MK4 (I have a Epia, so i'll tell you if it works) but.....
Initial wait = 1M pot
Cut Power time = 500K pot
200K pot? what is that for?

Boytoy .. 200k pot is for generating the ATX pulse. You can set how long you want that pluse to be.
