HD 7870 upgrade help

ralfie35 · Feb 23, 2014

Hello all and thanks in advance for your help...im a total noob to upgrading PC's...I have an HP Phoenix H9-1350 and i just ordered an XFX HD 7870 DD a few minutes ago...I was looking online and found that it requires a 6 and 8 pin connector. Can i plug this in with ease on my system?

From the link: PCI-E power connector (for high-end video cards): 2

Now I cant tell you for sure, since it dosent specify which type it is, or the PSU itself. But it has a chance, if the connectors are 6+2 you will have no problem. If they are both 6 pin (Which they likely are) you are going to have to use both 6 pin in an adapter to make an 8 pin, and use two molex connectors to make a single 6 pin.
That or replace the PSU.

its not easy to tell from the photo, but it looks like you have two 6pin connectors, and I think the extra 2 pin white connectors can make one of them up to 8.

I should think you'll be ok. I'd be suprised if the card isnt just two 6 pin connectors, my 7870 is, and every other gfx card I have had for the last few years.

From the picture it looks like you will have the right cords 8 pin white 6 pin black. Maybe not the most space tho, pretty sure it's a bulky card.

thank you so much!!!!...i know im gonna have to do some cable management(whats in the picture is straight from HP), but i know the card will fit, no problem....i measured my case...and i found videos online where people fit hd 7950s and up in it

The only other issue might be the power of your psu. I cant tell the wattage from that photo. You'll want no less than 600watts from a good quality psu.

it actually is 600w

You should get away with that, as long as its a decent quality psu with 80% or more efficiency. It will be something to keep an eye on tho.

Good luck.

For a single card that PSU is plenty, even if its not 80+ certified. Those connectors are a 6 pin and a 6+2 pin.

cool! one more question: since this is my first attempt at upgrading my video card, is there anything I need to do as far as software? the H9-1350 comes with an HD 7670 stock. Do I need to do anything special or is it as simple as putting the new card in and plugging it up? (sorry for all the questions...i just wanna be sure)

You have to uninstall the video card drivers. You go into the device manager and hit uninstall on the graphics and displays tab.
