It's pretty much just floppy (12V) which is bugger all and RS232 (-12) which is the square root of the former.

I think some sound stuff may use 12v. But it's still not much power wise.

@mrbombermillzy had a look at that (SFX-200W), looks good but can't find minimum load specs for it, found a checkmate pdf that actually talks about it (see quote below) so strange the SFX PSU they sell wouldn't have the specs listed fully

I was a backer for the A1500+ Checkmate Kickstarter and because the case was made to house an A500/A1200/RPi/etc, there was concern among some of the backers (me included) about sourcing a suitable PSU which would run with such small loads.

Steven Jones actually did a video recommending a certain make/model (I can't find that specific video; has made quite a few about various things relating to the Checkmate case, so it would be a matter of trawling through several very long YT vids).

However, I'm pretty sure he has found this one does the job (also recommending that its not for high end PC use), or I'm pretty positive that he would not be selling it to work with this case.

If you are still in any doubt (after the above), maybe contact Steve to double check.

thanks all, I reached out to the sellers of :

who referred me to Keelog the actual manufacturer, their response when asked about minimum load spec was, and I quote :

We did not conduct special tests in this area.

I got nice high level diagram that at least to show 3 separate drivers for each voltage



That's about as much 'technical' as they were gonna get.


So took the plunge and will see how my Falcon likes it . . . . or not. :|
