Hi,

Bought a new computer today and having some trouble getting a video card working with it.

Specs:

Computer:
HP Pavilion 500-164
AMD a8-6500
8 Gig Ram

OEM Power Supply was only 300 watts so I replaced it.

New Power Supply:
Thermaltake TR2-600W
It states it supports the latest AMD/NVIDIA Cards

New Video Card:
Radeon R9 270X
States it requires 500W PS or greater
Requires 2x PCI-E 6-Pin Connectors

I checked the PC first with the OEM specs, good to go. I replaced the PS and installed the video card. I get six long beeps and nothing on the screen.

According to everything I've found that indicates an issue with the video/graphics. The documentation for the video states it needs two independent 6-pin PCI-E connectors. This PS has two but they are daisy chained.

It came with 2x molex > PCI-E connectors so I tried one PCI-E connector and one molex to pci-e. Same issue.

The sales rep at Best Buy said she had to get a better PS because while the wattage was enough, there wasn't enough amps being put out by the PS. Not sure if that makes sense or not.

I've checked around the interwebz quite a bit. The only thing I can find is maybe it's a BIOS setting but after looking through it I didn't see anything.

BIOS or not enough power is all I can come up with.

Any ideas or help would be most appreciated!

There are a few possibilities:

1) GPU is not seated correctly
2) GPU is DOA
3) PSU is not pushing enough out to power it

My suggestion to you is to test the GPU in another rig just to see if it works, or if you got it from BestBuy have them replace it with another and test that the new one works in your rig. The main thing though is simply to be sure the GPU is seated fully, even if the PSU wasn't pushing enough for the GPU at load it should still boot up.

From what I can see the motherboard you have really shouldn't have any issues running the R9 270x. Just be sure that you have the GPU placed in the PCI-E 2.0 x16 slot and not the PCI-E 2.0 x1 slot.

As far as my 7850 is concerned, on a Gigabyte MB, it gave 1 long beep followed by 2 short beeps. That would be graphics error. I tried reseating the RAM, occasionally that helped. However, I thing reseating the GPU solves most of the problem. The contact areas between the GPU and the PCI slot is not big enough. Some dust may interfere. I had this problem every time I cleaned my chassis with a blower. Maybe some dust particles got inside.

Try re-seating. That might just work!
