Your card deosn't have one as it's not needed
Rubbish! Not every GPU needs the extra power so doesn't have a 6/8-pin connector. A reference Radeon 7750 doesn't have one either (it's a 55W card).
So you power it with what??? Wind power...

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. 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

try re-seat the card. Or change to another PCIE slot.

.I tried, it's been in and out multiple times. There is only one PCIe slot on the motherboard
Soo...decent GPU for £50-£70? Anyone? I gots a new computer and I cant even use it :'(
.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.
