HP Z420 support gtx 980 ti

[Anu0512]

Hi,
Does HP Z420 support GTX 980 Ti GPU ?

There few problems I'm facing

1- I put GTX 980 Ti GPU and change the PSU corsair AX 860i but system does not ON

2- When I put GTX 980 Ti GPU and power separately still system giving beep and red light

Separately means- For GPU I'm using different PSU and for whole system default HP Delta PSU.

3- When I try to run GTX 980 Ti with HP delta PSU system shows insufficient power for GTX 980 Ti, it required more power.

Kindly help me I don't what I'm doing wrong here.

@Anu0512, welcome to the forum.

I feel your frustrations.

The first thing to check is to see if the motherboard has UEFI or a standard/Legacy BIOS.  HP didn't begin using UEFI until mid-October, 2012.  If it is Legacy the video card will not work.

If it is UEFI, does the video card have additional power connectors?  If so, are they connected?

Hi,

Thank you very much for the reply, I really appreciate. I system is ON now. It was due to power problem. Sorry I was busy with problem

Man believe me when I changed the Power Supply it can't be fit due precise holes for HP power supply and there 18 Pin motherboard connector.  Really HP made system in that way, the only HP parts can be fitted. 

I have few questions:

• How I can check UEFI or a standard/Legacy BIOS thing.
• I have old version of BIOS should I update to newer version? But I don’t want messed up my GPU.

This what mention in new version of BIOS

“The following enhancements have been made in BIOS version 03.90:
This release improves security of UEFI code and variables and includes mitigation for the following vulnerabilities. HP strongly recommends promptly transitioning to these updated BIOS versions which supersede all previous releases.”

• My BIOS information, I retrieve this details via software Aida 64:

Thank you for the additional information, @Anu0512.

The motherboard does have Compaq EFI which is the same as UEFI.  This is good.

Now, here is a possible option to make the power supply work.  You can contact the seller to see what they have to say.

You can measure the space where the video card is installed to see if the card will fit.

I try to install another PSU and now GPU is working fine. Now the problem is I try to install fresh window 7 ultimate  but after the installation is completed and system restart after installation system  crash and pc restart again with problem. Is there any other settings required for windows installation ?

i'm also getting error message in boot "921 front usb not connected"

Thank you for the additional information, @Anu0512. 

I am glad that the video card works.  I am not certain if the BIOS has Secure Boot, but if it does, you may have to disable it to get Ultimate to install properly.  The specs on the computer show Win 7 Pro, and all versions of Win 8, but no Win7 Ultimate.  I am not certain why this is.

[Anu0512]

Secure boot is disable. I install the windows via USB drive even for this I waste half an hour. The window installation process is completed, you know after ON system i can see the window logo but suddenly it crashes. Should I try re installation or try to install Pro version but I don't think so there will be any difference the only difference is encryption of hard drive in ultimate version.

[old_geekster]

I definitely think that you should try to reinstall it.  I am not certain that it will make a difference, but this is what I would do in your situation.

[Anu0512]

Is possible to get correct BIOS setting so i can install the windows and run the computer.

I wish I had an answer for you, but I can't think of anything else to try.  The BIOS settings that you tried are what I would have recommended.
