Be glad you didn't buy this failed power supply
« on: April 27, 2008, 04:18:48 AM »
There is so much wrong with THIS I don't know where to start :crazy:

Dragos bought this piss poor power supply and it failed after a few hours.

-edit-
For the record I had no idea who made this power supply when I first posted the picture here. Now that the builder is known I want to be clear I think this gentleman did not have bad intentions, is that clear? I have personally bought custom roms from him and found him to be a nice guy. I would probably buy from him again, just not a custom power supply.

It looks quite "home-brew", but I don't think there's anything inherently wrong in rigging up a power supply like this, is there?  One power supply provides 5V for 5V pins, while the other supplies 9 or 12V for those pins.  

Sure it may be a little jury rigged, but it should work just as well as something more "factory made".

Of course, if poor quality parts are used, one of the power supplies might fail, as in this case.  But that's not a design problem.

Well....actually, there could have been a little more ventilation added.  Actually, if I had made this, I probably wouldn't have put it in that beige case at all, it may give it a neater appearance, but it restricts airflow around the black wall-wart adapters. Perhaps that's the cause of the premature failure.

Actually no, especially it was sold as a professional product afaik. This looks like a train wreck and the fact it failed after only a couple hours of use proves it. Looking at the physical size of these wall warts, there is no way their amperage is rated high enough for the intended application. DC wall warts typically are not internally regulated, coupled being greatly undersized there is a huge potential of improper voltage levels. The fact this failed was luck, opposed to destroying the C64.

Furthermore these wall warts being loose plugged into an generic extension cord inside a plastic closure with no fusing is so wrong I don't know where to start. I guess the owner could have cooked marshmallows over his burning house..

The first hint shoulda been that it rattled when you shook it. :-)

The discussion continues on lemon64.

As I posted on lemon64, I don't see ill intentions but it is ill-advised.
