Need some help: No signal after installing new video card

[Ab S]

I am new here at the PC forum but active at the Sony Cybershot forum.

Hope someone can help me: A few day ago I purchased a new video card ASUS Dual GeForce RTX 2060 6G EVO for my PC. I am using the Topaz AI family and DxO PureRAW DeepPrime.

The card fits perfectly to the PCIe 3.0 x16 slot and after powering up the led illumination on the videocard is working. Power is supplied by the PCIe slot. I used my existing HDMI cable to connect to the monitor. Changed cables to be sure, still no signal. What I noticed is 4 or so short beeps when powering up the PC . With the old video card (GTX 750Ti) everything works well (and no such beeps at starting up).

What can be wrong or am I doing wrong? In particular: the new RTX 2060 card has an 8-pin external power connector, which I am not using. Could that be the problem? According to the customer service of the shop where I bought the card, power only through the PCIe slot should be okay...

Below some pictures of the RTX 2060 video card installed in the PC.

RTX 2060 videocard installed in its PCIe 3.0 x16 slot and illumination active. Note the external 8-pin power connector at the right side of the card not connected.

HDMI cable at the rear side of the video card connect to the monitor

The result so far :-(

Looking forward to your advice

Many thanks,

It looks to me like your video card requires a power connection - see the 8-pin connector at the top of the card on the opposite end of the card from the the video connectors? Find an unused lead from your power supply that matches that connector and plug it in.

Thamks for your swift response!

If I connect the video card with a cable to the power supply, does that do no harm (interfer) with the power supplied via the PCIe 3.0 x16 bus to the card? In other words: just connect the 8-pin connector to the power supply?

Thanks again,

My advice is to be skeptical of what salespersons tell you; I've heard truly ridiculous, unsolicited claims at one of the local Best Buy stores.

Sean is very likely right; if that card didn't need the auxiliary power, it wouldn't have the socket. Yes, connect it up and see if that fixes the problem.

No hands-on experience, but ASUS says the card "requires" the power plug:

 

[NickZ2016]

Just google Nvidia 2060 power requirements. A slot provides IIRC 60 watts. The card is likely closer to 200. You need to make up the difference with the power cable.

Older Asus cards would actually put a warning up telling you to plug the thing in to boot.

Connecting the extra power connector will not damage the card. It needs it because the PCI slot can't deliver enough power on its own. If it wasn't required it would not be there.

Thanks, clear!

Now the next problem: the power supply is completely closed with the existing wires fixed inside, and the warning "Do not open power supply cover"

Indeed I should have not trusted the salesperson saying that power is going via the PCIe bus..

Completely closed power supply (what a desaster)..

DON'T EVEN THINK about opening the case. I can't tell from your photo if you have a spare 8 pin but it would be in the bundle of big cables already coming out of the PSU.

 

[Ab S]

..but, at the other side of the case I found a lot of loose cables with...connectors!

There are three 4-pin connectors and two 6-pin connectors (saying PCI-E), see picture below. Can I use two of these 4-pin connectors to connect to the video card without blowing up everything?

Cables with connectors coming from the power supply

Many thanks again!

In that tucked away bundle of cables exiting the PSU, you should find the one you need.
There might be a 6+2, rather than an 8 pin.

I think you are miss understanding the good advice that you have been given.

There are two basic types of power supply , firstly the fixed cable units, and they have a selection of fixed cables with connectors for varying uses in your PC. If you don't have a spare cable of the correct type and connector unused in your PC then you are in bother. The second type of power supply is the same to look at but has just connectors on its outside and interchangeable cables with plugs that can be used as needed.

Your Power supply is the fixed type it seems so you need to look at the loom of cables that come from this black box and see if an eight pin PCIe cable is available to run to your card. As for the salesman , he is dumb sadly. There are cards that only use the motherboard PCIe connector to transfer power, but they tend to be lower power cards, and don't have extra connectors. My graphics card , similar to yours but more powerful has motherboard power where it plugs in, plus both an eight pin and a six pin power connector to give it enough power.

If you don't have a spare unused eight pin on your power supply then you will have to change your power supply to make this work. I might suggest check and come back to us once you have had a good look.

No. 4 pin equal Molex. You need PCIE.

You can find six pin to eight pin adapters on Amazon. Read the reviews closely. For a 2060 might not be an issue but I wouldn't want to try it with a bigger card.

Your PSU is on the low side. You might want to think about changing that in the future if you add anything else.

 

[kciuk aka Ken60]

Looking at your spare cables the one with 6 connectors and the one with two work together as an eight . If you free them from the loom and look at them you will see they are made to fit side by side. They even have PCIe written on them !

Like that. No idea but the reviews seem okay

Believe it. Don't open the PSU case. Capacitors can hold a dangerous charge even with the PSU unplugged.

It's unlikely that there is an 8-pin plug inside.

Indeed I should have not trusted the salesperson saying that power is going via the PCIe bus..

https://www.coolermaster.com/catalog/legacy-products/power/b500-ver2/#specifications

However, here are the specs for that RS-500-ACAB-B1; good for you for providing the image!

It says it has "PCI-e 6+2 Pin Connectors 2". A 6-pin+a 2-pin beside it should work for an 8-pin.

Do you have those? Edit: after looking at your image of the cables, I think you do! Try that.

I don't think the two 4-pin connectors are quite the same.

Yes, thanks, I have two bundles with for each bundle a PCIe-6 pins and a 2 pins connector tied together. I am going to try and let you know if it works!

I had to use a dual 6 pin to single 8 pin adapter on my previous computer. A single 6 pin only supplies ~75W. Just another option if it's needed.

Sometimes I look at posts from people I've placed on my IGNORE list. When I do, I'm quickly reminded of why I chose to ignore them in the first place.

 

[Ab S]

It works, thanks to your advice!

There was a bundle of cables with connectors at the backside of the PC coming from the power supply: A PCIe 6-pins connector was tied together with a 2-pins connector. I connected these to the 8-pin connector of the video card and had immediately signal on my monitor. After that I downloaded the applicable drivers. DxO PureRAW is more than a factor 4 faster than with my previous card!

Another problem now seems that the color is not correct, less saturation. I will have a look at the ASUS site.
