shouldn't pwrsuppy fan still run if ?

[japerritt]

shouldn't a power suppy still fun even if there are no compents connected to it? i am trying to build my 1st pc. i connected motherboard, video card, monitor and nothing( no powersuppy fan running either).. disconnected all components and powered up .. still no power suppy fan. checked power cable and its good. i am gettting 5v dc and 4.5 on 2 of the cables (purple and green)coming out of power supply. the fuse is good!
do i deffinitley have a bad power supply????
thanks jody

Take an ohm meter or a test light or something to test it don't presume it. I did that and mad a fool of my self at the store trying to return it.

rylan.. take a meter to what? i did meter the outputs of the power supply, i got 5 volts dc on purple wire and 4.5volts dc on the green wire .. again the fan doesnt' run , the power supply fuse is good (i metered this too).. i'm almost positive its bad! i just wanna be sure????????this is my first attempt at building a pc.
the power cable is good and has a tight connection (metered it too)_ ...... what do yall think, i got all my components and can't do a thing.. it's killing me.. jody

How long is the power supply on? It's possible, somewhat unlikely, that you have a smart fan that only comes on when a certain temperature is reached. What is the make and model of the power supply?
Oh, forgot to ask, Is this an ATX supply?

hey, it is a atx power supply.. made by Deer computer co. medel is DR-250atx.. i have not left the power on very long.. when i went to test it, just the mother board, ram , cpu , and video nothing happened.. shouldn't there be more ouputs from the power suppy besides a 5 and 4.5 volts dc?

You should be able to find the following
+5vdc, -5vdc, +12vdc, -12vdc.

Edit- I see you posted twice and you listed different voltages that were written on your powersupply- edit

Hi japerritt

Please do not post the same thread in more than one forum. That makes it difficult to keep a common troubleshooting thread going because replies are scattered. Your best bet is to choose the most appropriate forum for your topic.
