    How is this done? Can someone give me a tutorial? I experienced power problems on both of my N64s and I suspect the problem is with my n64 power supply.

    I guess i should add more info. i have been having some trouble with my n64 power supply for the past 4 days or so.

    the actual problem is that whenever i plug in the power supply, and turn on the n64, the LED turns on for like a split second and then goes off again. i am sure it is no problem with the game pak, controller or other accessories.

    i replaced the power cord of the power supply with a new one, and surprisingly it worked. however, after 2 days the problem occured again.

    i tried to get rid of any possible humidity, cleaned it and verified the outlet works fine. i am not sure what the problem is. i have tried with another n64 and the problem happened there too, so i am assuming it is an issue with the power supply.

    could be several reassons, but for what ive seen its probably dry solder on the n64 power pinout, try to resolder them and see if it does the trick

    Using a pc power supply would be very simple mod to do, just wire the correct voltages to the correct pins, you could use the the plug from the older n64 psu assuming its defective

    How would I do that? I'm having trouble trying to open the power supply, I'm assuming you need some sort of special screwdriver which you can only get online, I hope that's not the case. :|

    Yes they require a game bit. Don't operate on video game hardware without one. There are work arounds for buying a game bit like melting pens and placing them over the game bit very fast. But why would subject your lungs to that for a less than 15$ part. Also the pen trick doesn't work for screws that have been put in there tightly, and you have the chance of marbling the plastic. Additionally you can use the soldering iron method. This is where you heat the screw up until it free floats, and pull it out with a pair of pliers. Obviously this is destructive to the plastics, bad for your lungs, and there is a small chance that you can get it back together.

    Just pick up the long shank 3.5/4.5 mm game bits and open just about any video game system:
    http://www.ebay.com/itm/SET-3-8mm-4...t=LH_DefaultDomain_0&var=&hash=item9758ee112c

    Not me selling it^

    Do you or have you ever soldered? because it might be cheaper/less ugly of a setup, for you to buy another used N64 and a power protection strip.:shrug: I solder about 2 times a week, and that's the route I would go. Especially if I didn't have the right tools for the job.
    N64's aren't really the golden system anymore and can be picked up usually for less than that gamebit set.


    as for getting the requires voltages out of a Atx power supply. Google the n64 power supply/ATX pinout. You will notice that whenever you put the green wire(PS_ON) to any of the black GND/Ground wires the power supply will turn on. If you put a switch here just be sure it's a single pole/single throw meant for automobile applications. Then just solder up the needed voltages using the N64 power supply pin out you got from Google too.

    BTW if you don't put a switch on the power supply, it will burn up if you don't have a load on it(ie the n64 is turned off). You can always unplug it though.

    I can draw pictures of what needs to be done, but I hope you get it from here.

    hmm, well i was thinking to try to resolder the pins. would that require a gamebit? im hoping not, because i honestly dont want to order one (why not just order a new power supply instead, same price pretty much) and i tried to make one from a bic pen but failed like 3 times.

    so yeah i want to try and resolder the pins, but ive never done this sort of stuff before. could you please provide some clear-cut steps for me to do this?

    Yes to resolder the pins you need a gamebit, the screws in the N64 PSU are gamebit screws.
    Just aside, the N64 doesn't use all that much power, probably like 20/30 Watts or something. If you swap to using a PC PSU, they're generally in the range of 350-650 Watts for most PC setups (although some are over 1000), so just remember if you do use a PC PSU you'll potentially be eating well over 10 times more power.

    Wrong, a 600w PSU will only use as much as the N64 is using. Same with 1500w PSU (same with computer to).

    I ran an N64 on an old ATX PSU once, worked fine.

    well yeah.. i was hoping i wouldn't need one because then i would have to order from ebay which is pointless because i could just buy a new power supply instead.

    hmm, does it mean something if the n64 finally turned one once, for like 10 seconds and then turned off again?

    This thread is like 3 years old lol :p
    Any decent PSU will do the trick, the n64 draws bum all current, it may be more better to use 2 regulators and a laptop PSU
