Step 5: Mount the Header Board

Remember that whole metal or aluminum case of the SMPS is Ground/GND/Earth or whatever you call it.

So make sure that no +5 or +12 or +3.3V or -12V pin touches it.
That's why I have used long nuts to keep proper spacing.
Its totally fine if these nuts are tightened with screws on GND pad of the PCB.
<p>Just a note to let you know I have added this instructable to the collection: <br>Encyclopedia of ATX to Bench Power Supply Conversion <br>&gt;&gt; <a href="http://www.instructables.com/id/Encyclopedia-of-ATX-to-Bench-Power-Supply-Conversi/" rel="nofollow">http://www.instructables.com/id/Encyclopedia-of-ATX-to-Bench-Power-Supply-Conversi/</a><br>Take a look at about 70 different approaches to this project.</p>
My friend, based on your instructable, I made this. I used only 3.3, 5 and 12 V outputs and I followed your design more or less,Thank you for the idea and the detailed instructable. <br>I wanted to ask, fuses have to be 5A, or can I use a little less than the maximum Amperes for each voltage of the particular power supply I used?
Dang-it, I was just about to build 3 of these for my shop. I have all the parts &amp; was just about to draw up the pcb. Looks like you beat me to it &amp; saved me some work ... Only difference in mine is I have colour coded LEDs on each output &amp; no fuses. Thanks! &amp; good 'able.
