HDMI not plugging into the HDMI port after GPU change

[John_Fruit]

I recently bought a Sapphire Vapor-X R9 270X. I switched my old card with the Radeon card after watching multiple videos and tutorials(this is my 1st time actually doing this) and I encountered a problem, well, multiple problems.

My HDMI cable could not enter the HDMI port. I have a feeling that the way I placed the card is incorrect and it probably is incorrect. I switched back to my old card and the same problem occurred. I constantly switched between cards and in both, my HDMI ports looked slightly out of place which was weird as I did what I was told. I tried to move the cards a little to the point where my HDMI cable could physically connect but in doing, I was unable to tighten the screws. Previously, I could connect my HDMI cable into my old card. Do note that my PC was actually assembled by someone else when I first got it 2 years ago. Currently, I'm using my old card through VGA which is kind of faulty(the port, not the cable) so I have lines appearing on the screen which is kind of annoying.

Is there a specific way to put the card in? I am unable to provide pictures of the problem unfortunately. My old card is a Gigabyte GT 640 and my case is the Cooler Master K281, if that actually helps.

I also want to ask about the two 6 pin-to-MOLEX connectors. According to the manual, I have to connect 1 to my PSU, and the other to my mobo but I cant find the right port in my mobo. The manual doesn't really help much so I hope that someone can help me explain these 2 connectors and also how to connect them.

Thanks.

Graphics cards can be inserted only one way in the PCI slot. After it is inserted, make sure that the latch is engaged; you will hear a distinctive click sound.

Regarding the cable connecting the graphics card to the display; are you referring to the DVI port, or the display port? Either one will work.

Regarding power to the graphics card. The two 6-pins PCI power connectors must be plugged into the graphics card delivering power to the graphics card from the PSU. Refer to the manual. It will help if you post the make and model of the PSU. The motherboard details can ve obtained by running "SPECCY" - https://www.piriform.com/speccy

I definitely heard a click sound. The problem is, my HDMI port(not my DVI port nor my DisplayPort as HDMI is my only option for my monitor aside from VGA) is not physically accessible by my HDMI cable, it just wont fit in. If I try to connect the cable to the port with the card outside the case, it actually connects. The worse part is that the problem is present in both cards.(Again, I was able to connect my HDMI cable into my old card before all of this happened) If possible, a video or tutorial on inserting GPUs into PCIe slots would be helpful.

Regarding the two 6 pins, my manual vaguely states that I can(note the word "can") connect one 6-pin to my PSU, and one into my mobo. In fact, my manual is just a vague picture of what I just said. Does plugging both 6 pins into my PSU work? Can I just, not plug the other 6 pin?

My PSU is a Cooler Master Extreme 2 625 watts

Since all you did was to change graphics cards, connect the new card identical to the old card.

Regarding the HDMI cable; these cables are generally not manufactured to very high standards (same with USB cables) and it may be possible that the cable 'fit' is the problem. Try a different cable, or try switching the ends of the cable.

Some motherboards have an auxiliary power connector for graphics cards. This aux. power is for SLI situations where more than one graphics card is installed. For a single card, this aux. power is not needed. The motherboard manual will explain this.

Okay, I changed cards again(back to my AMD card) and apparently, it only powers when I connect both auxiliary power connectors. Is it okay if I connect both to my PSU since the only aux. power connectors on my mobo are already occupied by my PSU.

Yes, it is fine to connect the aux. power as well as the PCI (graphics card) power to the PSU. If you run out of outlets in the PSU, you may use a splitter. Similar to this one - http://www.newegg.com/Product/Product.aspx?Item=N82E16812200935

Make sure that the cable length is suitable (long enough). Your local computer stores as well as Walmart (some locations) have this.
