I've come across this site that explains how to use a PSU without the need of a motherboard.Best regards,Pedrohttp://modtown.co.uk/mt/article2.php?id=psumod

Thank you! Good timing, I have been wanting to convert an old PSU into a bench PS.John

I'm glad I could help someone ;)Best regards,Pedro

>Thank you! Good timing, I have been wanting to convert an>old PSU into a bench PS.>>JohnThe old one might be just plain AT, if it is the case, those work without any modification. AT supplies have a hardware power switch that does not need a motherboard conneted. At least mine doesnt.Tuomas

Thanks for the heads up. No, this one is an ATX.John

Guys,Does these types of PSUs give a better DC voltage than your average battery eliminator thingie? And what different voltages are available from this kind of PSU. I would guess you have +5, -5, +12V outputs? Any more?Reason for asking is that I was thinking this may be good for running an FSBus cluster of boards? (See the Trouble shooting FSBus thread for more details ;-))Regards,

(See the Trouble shooting>FSBus thread for more details ;-))You can power FSBUS with the 12V - just put a heatsink to the regulator on the COM-board.The good thing is that PSU's have more power than those battery eliminators, have nice connectors and provide both 12V and 5V at the same time with several connectors, so they make a pretty nice "powerhouse" to feed electricity to many things in the home cockpit.Tuomas
