Graphics Card not detected, drivers wont install.

Hi, I am building my first computer, and I chose an AMD Radeon HD 7870 XT for my graphics card. I was having some problems installing it, so I decided to install windows 8 first, so after that I installed the video card and it doesn't seem to be working. The fans on the card are spinning, so I know that's not the problem. Also, when I try to install the drivers, it seems to go well, until the end, where it says "Warning, errors have occurred, please see log". I click the log and no errors are listed -_-. Please help me.

Specs:

i3-3220
MSI Z77a-G45 Gaming
1tb hard drive
Corsair CX500M

    7870 XT is a broken 7950 which still requires a 500w PSU

    However, the CX series is a budget PSU so ....... but It still shud be OK

    Does device manager see the card ?

    Tried latest drivers ?

    Uninstalled, cleaned registry of all things AMD and tried again ?

    500W (or greater) power supply with one 75W 6-pin PCI Express power connector recommended. Your PSU is 500 peak.
  5. The 7950 only draws 138 watts ..... the 7870 XT is a 7950 with part of it broken or disabled so draws less.

  6. Interesting Jack. Everything I've seen say's its closer to a 200W card. The powertune limit is 200W.

    http://www.anandtech.com/show/5476/amd-radeon-7950-review/16

    Notice idle is around 100W, while the gaming load is 350W(ish). I know the CPU load is in there as well, but I would believe the 200W powertune figures over 138W.

    All this said I would think the CX500 should be enough. Test in a different system if you can. Is the card seen there?
  7. Device Manager doesn't see the card, and I am having a problem installing the drivers, as I stated earlier. Also, upon initial startup, the fans on the video card start, then stop for around 3 seconds, then start again.

    Also, when I try plugging the monitor directly into the video card, the screen is blank.

    Again, the PSU is underpowered. Buy one from Best Buy or w/e then return after you test.

    Zombie, they say you need a 500W PSU because of the lying/junk PSUs that are out there. The Corsair PSU is enough.

    The problem with these responses and forums in general is that everyone looks for a tweak or test that is over the top. Keep it simple. Eliminate one problem at a time. If I am wrong, great! It cost nothing to buy then return a PSU. But at least then you complete a definitive test.
  11. Cost nothing to return a PSU? Restocking fee? Shipping? Even if you do it all in time, thanks for driving up the costs for whoever you bought it from. It also costs nothing to throw it into a friends rig and see if it works. AND it won't cost any company anything either.

    I don't have any other desktops to hook it up to, and no one I know that lives close by has one either. I ended up just buying a 650 watt PSU with free 2-day shipping, I'm hoping it works.
  13. I would have tried Craig's list. Hope it works out but it shouldn't be a PSU problem.
