From what you are describing I see no reason that the card would be dead.

Thanks for tips.

I am using no jumper, i am using the native 8 pin connectors on each psu's. Tried using two to check if it would power up, but it does nothing. I am already using this PSU to power 2xhd5870 with no trouble. To test this one, i removed them of course.

Going to try on my neighbour's pc which has a 1200w PSU, will report here once done.

Dude, remove that PSU from your rig immediately.

I hope you haven't fried your whole computer.

As everyone suggested, problem is the PSU itself. I just tried with both 8 pin connectors, and works perfectly!

Big THANKS to everyone!

Now i see the problem was that i need to have last two pins of second connector grounded aswell, which i couldnt due to this psu being 1x8pin and 1x6pin. I can get it now to work on my PSU with that, but i wont.

Now, i ask you one more thing: Which PSU brand do you recommend for 1x6990 + 1x5970?

Say 500w+500w. Will have this PSU just for these cards, not for the mainboard aswell. If this looks way too much, i can get two psu's so would go individually.

Thanks once again!!

Just don't freaking NEGLECT your PSU choice.

Stop buying crap, and go for something worth the money.

Just buy one quality power supply. Dicking around with two low-wattage ones is virtually never worth it.

Where are you located and what stores are you buying from?

The link isn't working. Could you tell me what you're getting?

32 amps is about 350 watts.. I don't think that PSU could handle anything more than a HTPC..

Dude, chuck that thing in the BIN NOW.

Theres a chance you killed your 6990, get a Corsair HX750 watt and call it a day.

It says an Antec True Power Quattro 1200W

I feel sorry for that 6990...
