Specs: windows 7, 4gb
I have a HP a1410n that I just got a "N8400gs-td512" video card for. Trying to find a manual for the card almost an hour on the net with no luck. I guess just install it and use it, but there is a small 2 prong plug on the top and was wondering if that was for power? Also the PSU is an Hipro HP-D3057F3R, 300w so is that enough power? Thanks.

If you disable the on-board port and do whatever else may be necessary to enable the card and if the PCIe slot is compatible and if the power supply is adequate then I'd guess the card is bad. But there have been a few threads where a good card wouldn't work even though it should have been compatible. Sometimes a bios upgrade fixes it; sometimes it doesn't. So I hesitate to say anything for sure especially since I don't have the hardware in front of me.

This is not the exact model buts its close. MSI doesn't recognise your model number so it is probably a discontinued model.

Yeah, the download for the manual there looks like it covers the entire 8400gs series.

Do you have the drivers:

Choose the options for Geforce 8 series 8400gs and then your OS. Note the drivers are different for 32 bit and 64 bit windows 7.

I went ahead and installed the card and the fan on it comes on but the PC is not showing it under device manager. So I hooked up another monitor to the video card and one to the PC vga and still not showing up. What am I doing wrong?

Yea this is my first video card install. So is the reason it's not showing up because I haven't installed the drivers?

You need to install the drivers.

But having said that, even without drivers you should still get something from the new video card even if it is the default resolution which is usually 600 x 800 and 16 bit colour.

Did you go into the BIOS and disable the on board Video?

OK I was going to but how would I be able to see what I'm doing if the screen goes blank.

You should still get a BIOS screen with or without drivers. If you are not getting a BIOS screen than there is something seriously wrong. Make sure you have the monitor plugged into the correct Video output, preferably the on board video to begin with.

What I would suggest is remove the new video card. Connect to the on board video and reboot. You should then get a BIOS screen. Disable the on board video and shut down.

Install the new video card and swap the monitor lead around and re-boot. If you still get nothing on the screen then either there is something wrong with the video or the power supply is not powerful enough to power the new cad.

It's to late to pull it out now. So tell me if this should have worked. #1. Left the card in. #2. Rebooted to bios and set primary video to pci-e. #3. Saved and rebooted. #4. Logged back on with it still hooked to on board VGA and had a windows screen. #5. Unplugged and moved to video card but no picture. If it should not work that way I'll try your way again tomorrow. So check back. Thanks

If the card is used do you know it to be good?

Maybe when you rebooted it auto-detected you were using the on-board and reset that as the video controller. Go back into bios setup and see what it says about the video adapter.

However you can get to the desktop, open device manager and see what it says there for 'display adapters'

It is not showing up under the device manager under display adapters. Yes it is used. But the fan on it is running if that means anything. And I still don't know what the small plug on the top of it is for as stated in the first question.

Download the manual from the link StuartS provided and see if it describes what the plug is for. I don't think it needs an external power connector but can't say for sure.

That's not much of a manual but it gives some specs. It needs at least a 350 watt PSU with 36 amps on the 12 volt rail but it doesn't mention a separate power connector. Check the 12 volt amp rating. Your 300 watt might work if it can supply the 36 amps.

Wait, I'm not sure about their power specs. 12 volts pushing 36 amps gives 432 watts. That way more than their required '350 watt or greater' PSU and that's just the 12 volt spec.

OK but shouldn't it still show up somewhere in the device manager? Like I said the fan runs. So it must be getting power or is it not getting enough to make it not show up in device manager?

If there's not enough power to run the card it may very well not show up in device manager. I can't say for sure. Of course it could also be that the card is bad. The fan running isn't really a good indicator of whether the card itself is good. That just means it's getting enough power to run the fan.

About the connector you were wondering about. Is this your card:

http://www.ebay.com/itm/MSI-NVIDIA-...

(You may need to click on 'show original listing' and then click or mouse-over on the picture to blow it up.) That's the best picture I could find of what is probably your card. The seller there has the fan connected externally. I don't know if that's the way it comes or if he added that fan and has to connect it externally.

In that picture the brackets are for a low-profile application which I think is the way you're using it. In that case the 15-pin VGA connector is separately connected to a plug and the connector itself is on a second bracket. If it was a high-profile bracket both monitor connections would be on the same bracket. If you don't have that VGA connector then you'll just have an unused plug-in on the card. Is that the one you're talking about? If so, then mystery solved. If not, I don't see another connection on that particular card. Is your card different than that one?

OK the HP a1410n isn't a low profile computer (don't know where I got the idea that's what you had) but take a look at the ebay picture and see if the VGA connector on the card is what you're wondering about.

No none of those are not my card. If you take a copy this>>> N8400gs-td512 <<< and google it will show you the exact card I have. Thanks for the help and I'll try what you said.

Unfortunately those pictures don't give any close-up detail. Other than the obvious connection for the 15-pin VGA port I can't tell if there's any other ones.

You originally mentioned it was a '2 prong plug' you were wondering about. All the PCIe cards I've seen that have external power requirements have a 6-connector plug. So while I can't say what the 2 prong plug is for I can say it's not to power the card.

If you can try the card in a computer with a bigger power supply that fits the card requirements we could find out if the card is good. If it doesn't work when the power requirements are met then it must be bad.

OK the biggest I have is the Dell Studio 540, think it has a 350w PSU. I'll try it later if you think that's enough. Anyway go to Newegg.com and they have a good picture you can blow up. The 2 prong plug is just forward of the gold heatsink and next to the single capacitor that is out by itself. (Not the plug that has the wires already it it). Thanks and hope that helps.

Yeah, I see it with the newegg pictures. That plug I'm certain is to power a 3rd party cooling fan. The stock fan it comes with probably has a proprietary connection that won't work with other fans.

The card has a better chance of working in the Dell since it has a bigger PSU. Just make sure it has a compatible PCIe x 16 slot.

Newegg reviews on that card show people running that card with 220W and 250W power supplies so it does not appear to be a wattage issue unless your power supply is going bad or is badly overrated. Testing on another machine may help confirm this.
Try popping out the card, cleaning the contacts with a clean pencil eraser and popping it in and out a couple of times to make sure the socket is not tarnished as well (burnishing it).

You have to be a little bit crazy to keep you from going insane.
