HPE h8-1287c GPU Upgrade

I have an HP hpe h8-1287c that I have made upgrades too. I installed a boot ssd, already transferred windows 7 sp1 64bit onto it. I took out the OEM ram and installed 4x4gb 1600mhz hyperx ram. I installed a new evga 450w bronze 80+ (bt) psu.

 

Before I bought the psu I tried to install a 1050ti mini because the OEM psu didnt have a GPU cable. But the mobo gave some beep codes that I couldn't find a guide online for. That's when I bought a rx 470 and the psu.

Now my problem is the PC boots but as soon as windows loads the fans on the GPU stop spinning and it's not detected anywhere in windows. I ended up having to update the bios straight from HP's website to try to fix the problem but it didn't help.

 

An AMD HD 7870 2gb does work in the build, and the rx 470 is tested in my main rig.

 

Cpu: i7 3770 with cryorig c7 cooler

Gpu: xfx rx 470 4gb

Mobo: ipmmb-FM (formosa) with bios version 8.21 rev.a

Psu: evga 450 bt

motherboards of prebuilt systems don't necessarily (and usually don't) follow PCIe 75w rule, quite often they are only good for 25w. That's probably why neither of the newer cards worked. As for the 7870, maybe it's just not pulling much power from the PCIe slot.

Wow I hope I don't have to change the mobo. Ivy bridge mobos are expensive.

It randomly started detecting the 470, and it tests fine in games. idek
