Hello and thank you to all of you who are reading this post!

I am seeking help because i bought a new graphics card (VTX3D HD 7870 X Edition) and i put it in my motherboard and the fan is spinning but she is not getting recognized by my computer and i don't know why! I downloaded this bios file witch i think its the latest one

Used the ez flash from asus and i didn't get an error or anything

But still nothing! It doesn't even show up on the device manager

http://prntscr.com/3nklux

I was wondering if it would be possible that the graphics card is not getting enough power?
Because i saw a power connecter outlet for her

But then again i watched 2 unboxing videos and it doesn't come with a power cord or anything!
Like this one!

Can anyone please help me??

If you didn't plug in the 6 pin power for the card, its probably why you're not getting an output. There should be a 6 pin that's on your power supply.

If your power supply doesn't have the right connectors it is very possible that it will not be able to power the 7870 so I suggest you buy a new one.
I recommend the Corsair CX500 500W PSU. For around $70.00 you get excellent 12V rail power output which is plenty for your card.
I'm running and i7 and an over clocked 7970 with the CX500, it is a very good buy.

Here it is: http://www.newegg.ca/Product/Product.aspx?Item=N82E1681... *It's even on special*

Cheers,

Specifications of the VTX3D Radeon HD 7870 GPU
http://www.gpuzoo.com/GPU-VTX3D/Radeon_HD_7870.html
Lists Power connectors needed as: 2 x 6-pin

You should be using a 500 watt power supply with two 6-pin PCIe power connectors.

I have a 500w psu i made a previous thread to see if it would support my new graphics card and they told me it did i even took a picture of my psu and everything just to make really sure that it would work so technically it would be something like this right??
