Hey,

I recently have had PC problems and Its between the Motherboard and the Graphics card. My question is can it be tested for power without a motherboard. I just want to see if the fan works.

Either way one of the two will be RMA'd

 

[compuman145]

No it can't i'm afraid, can't you test it in a friends machine?

 

[DazTora]

Yeah I can always do that, I was just curious

Thanks anyway : )

If you want to see whether the fan spins, you can try plugging the 6 pin into the card without plugging it into the mobo.

Or you can unplug the 3pin fan connector and somehow connect it to a molex

sure just jump the psu and plug it in...

Nah, it'll still need to be initialised by the motherboard. Although the fan connector to a molex or the motherboard. Oh wait no motherboard.

Also if you do manage to get it connected to the PSU you'll need to trip the PSU into turning on.

You should be able to disconnect the fan on the graphics card and put some power to it.
If your just looking to see if the fan spins.

Batteries should work shouldnt it for testing purposes. Just dont put too much power to it.

You do not need a motherboard to test a GPU fan. Just jump the PSU with a 6-pin plugged in and it should turn on at 100%.

 

[compuman145]

o'rly...

I thought it'd need a motherboard to initialize the GPU bios or something.

And how would one jump a PSU?

short the green wire to any black wire, its the green wire in the 24 pin connector, use anything, wire, staple, whatever it is, just gotta be bare metal

Take a paper clip and put one end into the connection to the green wire in the 24 pin and one in any black wire on the 24 pin.

I learned that from corsairs tech department when my tx750 was not working.

 

[DazTora]

Will it damage the PSU..

Hell will it damage me?

 

[corx]

Well, if the gpu's fan is spinning that doesn't mean it is working, I have an old 8600gts.. the fan spins but there is no signal on the monitor so it is damaged/faulty whatever.

 

[DazTora]

I aint trying this if it will shock me or damage the card / PSU >_<

you will be fine, it won't shock you or damage the card\\psu. I have jumped my testing PSU like 1000times and Im still here

[DazTora]

Right ok thanks will try this in the morn...well later on : )

 

[1156]

youll be fine aye, its what the motherboard does to signal the power supply to turn on, have personally done it heaps, never killed a psu doing it

 

[DazTora]

Ok upon further inspection, my PSU has one green wire and quite a few black ones. Will any black one do. I have it near me now but I am just making doubly sure.
