Hi all,
I managed to get my hands on a solid ATX PSU and wanted to convert it to a lab supply for electronic projects and what not. It has all the rails I would ever need but my worry is that the current capability is a bit too high for my liking (up to 40A for the 5V rail and 38A for the +12V rail).
I was looking into placing PTC fuses in series with all rails with a trip current of around 0.5A to 1A as I really don't need too much power for what I'm doing.
Does anyone have any recommendations for PTCs for this or another means of doing the same thing?
P.S. Silly question, but if all my rails have fuses, would the ground wires also need a fuse as well, being earthed and all...?
Thanks,
JP
