Question HP PC doesn't detect GPU ?

[Sparkster2348]

I just purchased an old 2nd hand 4th gen HP ProDesk 600 G1 Tower and I am trying to put an old GTX 950 in it.

When I initially plug it in, it cycles 3 times without displaying and then gives me beep indicating it can't detect the GPU.
I can then manually power it on and off but it will only give display via the iGPU.

It's coming up in device manager and I have installed the drivers, but when I try and boot into the bios it does the exact same thing as when I first plug it in and it won't post. But it continues to post into windows just fine on the iGPU.

I know the GPU is fine as it works on 2 other PCs.
I know the PCIE port is fine otherwise it wouldn't register the GPU
The seller of the HP ProDesk 600 G1 Tower was running a 1050TI prior to selling it to me and doing a clean install.

So I presume its a combability issue between the HP BIOS and this GPU ?

Can you even update the BIOS on these old machines?

Anyone got any other suggestions?

If I remember right the GTX 950 requires a 6-pin aux PCIE power connector. Again if i'm not mistaken the 1050 Ti doesn't need a 6-pin.

Does the PSU in your system have/provide that 6-pin output?

This particular single fan model of 950 doesn't have a 6 pin slot or require a 6 pin connector

Some 1050 Ti cards do require external power. That was a consideration when I bought mine. I got the fastest one that I could find that didn't need it.

I'm wondering how there can be a GTX 950 without a power connector, since it's supposed to be a 90W card, and you can't draw that from the PCIe slot alone.

What's the exact model of the 950?

It's right here:

Funnily enough it was something so simple.
The issue turned out to be either a faulty DVI cable or DVI port on the monitor.
One of the last things I ended up trying several days later was just getting one of the HDMI monitors and plugging it into that and volia, it worked immediately.

For whatever reason I still can't get into the bios when the card is connected, which seems to be a fairly common issue not related to issue I was concerned about, and is going to be of no consequence to the person inheriting this PC.

Odd as the specs and images for that model show it has a 6-pin power connector.

Sorry I initially linked the wrong one, you got in there before my edit lol.

You can see on the GPU bios page what the intended power draw is:
https://www.techpowerup.com/vgabios/223953/223953
Target: 75.0W / Limit: 87.0 W (This is the bios it came with)

6 pin model:

Target: 95.0 W / Limit: 113.0 W

I only stumbled across this when I was trouble shooting and seeing if I needed to flash the card or not,

But yeah, definitely no 6 pin slot on this card
