CoffeeFiend Posted January 7, 2007 Share Posted January 7, 2007 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. Link to comment Share on other sites More sharing options...
ethanmcf Posted January 7, 2007 Author Share Posted January 7, 2007 Hellothanks 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 firstThanksEthan Link to comment Share on other sites More sharing options...
ripken204 Posted January 7, 2007 Share Posted January 7, 2007 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. Link to comment Share on other sites More sharing options...

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. Link to comment Share on other sites More sharing options...

IcemanND Posted January 9, 2007 Share Posted January 9, 2007 Get yourself a PSU tester. Plugs in and has a button that when pressed give indicators if voltages are correct etc. Link to comment Share on other sites More sharing options...

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. Link to comment Share on other sites More sharing options...
