DIY Power Supply Thread - Questions and Help

[fredrik]

I have the dangerous prototypes one and it works fine (with the usual caveats about switched supplies, etc). No idea how robust the clones are…

Is there a way to build a Kosmo PSU out of ATX PSU?

One thing to keep in mind is that a computer PSU can sink a lot of amps into your circuit, and cause a lot of damage if you’ve made a mistake. You can use something like to get a bit of extra protection (it has polyfuses that turns things off at 1.25 A, long before the PSU detects a short, but that may still destroy things). But the beefier your supply, the more careful you need to be when powering things up the first time.
