power modules by pc power supply... suggestions?

hi!

i’m about to build a midimerger and a midi thru box, and i will power them with the internal pc power supply.

but i recently read a post by kc (reply 13)

http://69.56.171.55/~midibox/forum/index.php?topic=5116.0

that says to be aware of power spikes by the power supply itself…

i don’t want to burn IC… so… what do you suggest in order to protect the IC itself?? i originally thougth to insert the usual caps needed for the midibox (el.caps and the smaller one…) what besides this?

thanks!

actually, i have learn that i can also get 5V fromt he joystick port. i will try soon to power my module from this… and then let you know…

for now i have only mounted a fuse on the board.
