I did some reading and since radio shack doesn't have a 1ohm/25watt resistor then I calculated that a 2.5ohm resistor would give me 25 watts at 5vdc. I'm guessing, I'll have to move up to 3 ohms...
I have one such supply here that very certainly will not stabilise without a minimum of 15W loading on the 5v rail.
However, you are perfectly correct in that it *usually* only requires a few watts. Many need no external minimum load at all.
I haven't come across a single ATX supply that needs a minimum load. IIRC, some are even marketed on that basis.
I also have some 5v 250A power supplies - with 4 terminal outputs such that the actual supply can rise to 8v on full load.
I suppose it was easier to design as they are only single output but they need no minimum load at all. Still, I wish I had been given that project.
I keep hoping one will go wrong so I have an excuse to open it up and work out what the design is....
I don't really know why I bought them - they were sitting there in a scrap box and I just wanted to have them. Hundreds of amps has always appealed. My ex-husband didn't mind me buying such things - I suppose that I was a lot cheaper than someone who does the same thing with cars or clothes ;)

Make me your current husband. I won't ever object, and I even participate in "junk" purchases. I have six "old" "screamer" computers to prove that! :-] They were new though at one time. Some of my ancestors ran junk yards! I think a modern junk yard would be cool!
I'll bet my collection of junk is bigger than yours! I can't park inside my 30' * 40' garage, the 18' * 12' machine shop is so full that I can barely get to my drill press and the 12' * 12' tool shed is full to the door. Good thing that door opens out, not in. I have enough projects lined up to last me the rest of my life. ;-)
What a guy. :( For your information, Minnie Pearl was a country comedy stage act, not a real person. Sarah Cannon who was known as "Minnie Pearl" on the "grand Ole Opry" and at other country venues spent most of her life raising millions of dollars to help children around Nashville, Tennessee.

You're an idiot (what a dolt?). Minnie pearl was a regular on "The Beverly Hillbillies", as well as "Hee Haw". That was years AFTER she already had made her own fame doing country comedy. Granted it was her stage name, but so too was "Marilyn Monroe" a stage name. So what?
Yeah... so... she also wasn't the cutest peach in the bushel basket. Jeez... it was a joke... Get over it.

You link twinks are funny. I knew exactly who she was when I posted what I said, dufus.
