I am having some issues with my MDD.. Powers on fine for the first time then when powered off while not turn on again until it's unplugged and plugged back in... Any ideas
Thanks
Thanks
I would make my own power supply
I think all you really need is 12v, 5v, 3.3v, maybe -12v, and a relay or something to turn it on and off... But I don't really know anything about this...
I'm as much of a DIY guy as anyone else, but building a quality computer power supply isn't exactly just a matter of throwing a few parts together. You need to first step the power down with a transformer, then use a rectifier combined with a capacitor and probably an inductor to smooth it out(BTW, if your transformer steps down to an RMS AC voltage of 12V, you will get ~17V DC out of it when you do all this).
As far as I know, most modern computer PSUs are high frequency switching PSUs, which has quite a few advantages in that the transformer can be much smaller and it's easier to get a smooth DC voltage out of it.
If you want to tinker with one of these, your best bet is probably to use an ATX PSU.
