Asus 780 LED lights problem

[litwicki23]

hi guys, i recently bought a asus gtx 780 direct CU II, and i have a problem. Well this GPU has two led lights that turn on when you connect the pins. I plugged this in and only one of the lights turns on, the other one doesn't, So im not sure on how to proceed from here, is the GPU working with only one light on? My second Asus 780 DCII is working with 2 two green lights when is on . So this is bad card or what? I am connecting card the same way like second Asus 780 DCII which had 2 green lights on.

The lights mean that the cable is connected into the slot. You said you have a second one? How much watts do you have in your PSU?

The light could mean 2 things.

1.The cable isn't fully in the slot

2. The led is broken

PSU is XFX 750 W


Yes i mean second led is not working, i mean is not green or red. Just nothing is visible. Empty. Only 1 led is green.

I would say a 750 watt with 2 780s are around the ok area. But you're limited on what you can do (small overclocks)

In the PSU, there are PCIe cables for the GPU, I think the 780 is a 8 pin and 8 pin? idk, because my 780 ti from asus is 8 pin and 8 pin

well, most PSU have them, and it's 6 pin + 2 more, so you can convert it to a 8 pin. Take out the card from the moherboard first, and then put it back in. Then, take out the cables again, and plug in the 2 pin with the 6 pin. Maybe you didn't place them correctly. No lights means the cables aren't in the power connects.

When i put off cable from pcie slot i see a red light. But green light is just not working in that 1 pcie slot. So what do now? Broken led?

 

[Daniel Sudakov]

No, if a red light comes up, the lights are working fine. Red lights mean its not in. No lights means the cable isn't properly in. Green light means it's in and it's getting power.

only one of the pcie power led´s is green! 8 pin led is green but the 6 pin led is not lighting up. If i remove the 6 pin Cable the led is red as it should be. Using a XFX 750 W and i tryed switching PSU too but it shows the same.

Could the 6 pin green led be broken? Because there is 4 led´s, 2 on each Power connection (green/red).

I try my friends Asus 780 DirectCuII and lights are working properly , both are green. So cables are ok.

 

[Daniel Sudakov]

Really, that's weird. I know what you're talking about. But both of my lights are green, because I properly placed the cables. Yours could be different, because my 780 ti is 8 pin + 8 pin.

Ahhh damn, I forgot this. Whenever I took off my PSU cable, the card lights would go off because there's no power. It would only go red when there was no cable on the slot, or not properly seated. It turned green when the cable was on. Even when my computer is off, it's still green.

What's the second card doing? Is it also doing the same? I have a feeling it has something to do with the amount of power. ASUS cards are power hungry cards. Maybe 750 watts is not enough.

 

[litwicki23]

Like i say, other Asus DirectCu II 780 is showing ok, but both green ligths.

 

[Daniel Sudakov]

Does your friend have a bigger PSU? With around 850-1000 watts you can burrow? If the lights are working fine, there's nothing wrong with the card.

 

[litwicki23]

I tested hes Asus 780 on my pc and the same psu. His card is showing both green lights, while my card not , only one green.

 

[Daniel Sudakov]

Oh, so there's something wrong with the card. You might have to return to the store to get a new one.
