It's a **B Grade** Sapphire HD 7750 1024MB GDDR5 PCI-Express Graphics Card

Whether I use the DVI adaptor or HDMI out nothing displays on the screen, leaving me using the motherboards built in output.

I've checked in bios and there seems to be nothing in there to enable it. The fan powers on for about a second when I first turn the computer on but then it stops.

If you need to know the rest of my specs just ask! Thanks :)
 
Intel Core i3-3220 3.30GHz (Ivybridge) Socket LGA1155 Processor (77W) - Retail
Gigabyte H61MA-D3V Intel H61 (Socket 1155) DDR3 Motherboard
Toshiba (7K1000.D) 500GB SATA 6GB/s 32MB Cache - OEM (DT01ACA050)
Antec High Current Gamer 400W '80 Plus Bronze' Power Supply
Kingston HyperX Genesis Grey 8GB (2x4GB) DDR3 PC3-12800C9 1600MHz Dual Channel Kit (KHX1600C9D3X2K2/8GX)
Samsung SH-S222BB/BEBE 22x DVD±RW SATA ReWriter (Black) - OEM

After doing some digging around it seems I need a 6 pin PCI-e thing in my motherboard? Is this correct?

No, not 'in your motherboard'. You will need a 6 pin PCI-e power connector running from your PSU to the gfx card. Have you plugged this in?[/QUOTE]

There is nowhere to plug it in as far as I'm aware.. I've examined the card and can't see anything :/
 
After checking, and checking, and checking again, along with getting my brother to check, there is absolutely no where for anything to plug into this card in terms of power supply...it only has 3 outputs "DVI/DP/HD" and they're all outside the computer anyway

I read something about disabling my onboard graphics adaptor, is it worth me finding a guide on how to or is the gpu screwed?
 
Are you able to test it with another PC? If it's a 'B' grade item then it might have been returned by another customer for the same reason... OCUK do test them, but maybe it's a bit picky with certain boards or chipsets :confused:. Also, are you using all 24-pins on the motherboard power connector? Some boards still boot up using 20-pins (it's a 20+4-pin block)... Make sure both the 20-pin and 4-pin parts are connected to the motherboard ;).

Yep I'm using all 24 pins, you're prob right about the B grade thing, I had no idea that's what it meant. Looks like I'll be returning it. Thanks!

Any other decent graphics cards in the £50-£70 range? :)
 
Thank you :)

I'm just a bit iffy though, it states in the returns policy that unless an item is faulty they won't refund.

So another question, going by the specs I posted (above) is the card I currently own compatible with it? I assume it is but I just have to ask before risking wasting some postage money...
 
Let's just hope your actual PCI-E slot is not to blame (closely inspect it for any damaged/bent or misaligned pins). I would still keep an eye out for a cheap 7750/7770 as they're not bad for the price. Maybe even a GTX 650 ;).

It shouldn't be, the motherboard was brand new! I'll check tomorrow anyway. Too knackered right now
