What PSU do you have?

I don't know if these are physically the same connectors, but most PSUs also have an 8pin cable for use with modern motherboards.

You only have one 6pin pcie cable, which means you would need to buy a molex to 8pin pcie adaptor to get the card to work. However I have only seen a molex to 6pin pcie adaptor. Although if you can find one, the PSU certainly has enough amps and watts on the 12v rails to easily power the card.

Edit:- Type the following into google, then click the shopping tab, first product that appears. It should be black and green

"molex to 8 pin pcie"

When you get this plug the real 6pin pcie cable that your PSU has into the 6pin socket on the GPU, and then use this adaptor for the 8pin.

yep looks like a new psu now as well just setup my i7 with a 1900xt lol

Surely it's worth a punt to try the adaptor first? Your PSU should be able to run an i7 with a single card fine (38A on the 12v is fine).

cant find one m8,dident see it on overclockers m8

thnx for pointing out the 8 pin to the motherbaord was using a a 4pin from my e6600 setup was working ok thow ,just built an i7 30 minutes ago and cant put my 4890 in it have now put the 8 pin to motherboard
