But you don't really want to operate a switching PSU w/o any load for extended periods of time. They make dirt cheap half-decent lab PSUs - just need to add a dummy load on the 5v.

Hello
thanks for your Reply, the link you gave me was help ful and worked well,
and it is only to test the funcionality of a PSU, and or other COmponets such, as FDD or CD-ROM, without me needing to plug in in to my computer first
Thanks
Ethan

no problem, its usually a test done to check if ur psu actually works if your system isnt booting up and if things are not powering on.

Yes, it solved a few problems, and is good for futrue problems, say with customers etc

Indeed. I remember the old ones (c. 1980s) used to actually explode if run unloaded.

The newer ones have better regulation so they don't do that.

Get yourself a PSU tester. Plugs in and has a button that when pressed give indicators if voltages are correct etc.

can i ask something,
i know this may sound stupid, and is only for reference,
But how does it last longer in a Computer, than on its own?
Thanks
and by the way i dont intened to leave it running on its own, i just might have used it as a tempory Second PSU, for Client HDD Formats/backups etc
Thanks again

Probably less of an issue now than in the past, but PSU like to have a load to power.

If that is all you want find an old AT power supply either from an old machine, or out of a external drive cage like an external cd or hard drive than isn't used anymore. Then you don't have to short out two pins or add a switch, the old AT power supplies had their own on/off switch.

thats cool, i didnt think of that, thanks for that bit of info IcemanND.
Ill just have to mod my case to hold it
Thanks
