Can i use one 12v output of a PC power supply to turn on my Wii?
Anyone tried this. I think its safe.

We had a thread on a somewhat related note the other month (it certainly have some numbers worth looking at):

Back on topic most computer PSUs have a handful of rails inside them that have power draw limits in the tens of watts, I just checked my old 600W PSU and it has 12V rails rated for 13 to 18 amps depending on the reail, from the topic above "DC 12V 3.7A" so that is well within the limit for my old supply. If however you already have something running on the supply rail you have just earmarked for the wii (looking at graphics cards) or you pulled it from/it exists inside a vendor machine it may be different as many of those run very near limits.

If you are using a standalone PSU (no computer) then http://web2.murraystate.edu/andy.batts/ps/powersupply.htm (similar projects litter "hacker" sites but I like that one) might be of interest.

I suppose in theory yes it could work and work very well, in practice be sure to check the numbers both mathematically and with a multimeter.
