The spec must be easy to find, but I would have thought (hoped) that a PSU like that would be designed to work fine at any load. On the grounds that if you were having hardware problems the last thing you'd want would be for them to be exacerbated by a power supply not working because not all of your h/w was working.

I was thinking the same, that it should be okay if it is steady now without any load, hopefully with load should be fine too, the load will only be small anyway

One might think that, but a Google search for "ATX Power Supply Minimum Load" (even with the quotation marks) yields 10,000 hits, a random glance at which reveal many people moaning about the sort of problems I experienced when I tried this (albeit a few years ago). The usual advice given is, needless to say, to put very high power resistors of sufficiently low value across all the outputs (and maybe install a few extra fans ).

As regards your (very reasonable) point, I suppose that it's not unreasonable to assume that, unless it has literally burnt to a cinder, enough bits of a PC will usually still be drawing current to satisfy the minimum load requirements of the PSU.

Kind Regards, John

What problems did you have with yours John?

Unsteady voltages? Then heat, after you added the resistors to steady the voltage?

What problems did you have with yours John? Unsteady voltages?

Memories are fairly hazy (since I decided to give up on the idea, because of the problems), but IIRC 'disappearing voltage' (after a while of being there) was one of the issues. I did successfully use shunt resistors to get around the problems, but they wasted a lot of power and got very hot! It's possible that modern ATX PSU's are different/better in comparison with those I was playing with 'back then'.

As I said, there's a vast amount about this to be found on Google, largely from people doing, or trying to do what you (and I) wanted to do - so I suggest you do some reading.

I would personally say that there's nothing to compare with a real transformer in a general purpose 'bench PSU'

Hmmm alright

Thanks

I'll have a read-up
