Is my Power supply enough for this graphic card?

Is my Power supply enough for this graphic card?
Hi guys! I've been poking around the site for awhile now, looking at the builds and such and built two computers thanks to the valuable source of information here. I currently have some troubles installing a new graphic card into my computer. I don't know if my PS has enough power to deliver for this graphic card.

Whenever I start the computer, everything turns on except the black monitor. The monitor works because windows shows up when the card is not plugged in.
This is the graphic card:

This is the PS:

I know I have enough 500 Watts.
I have two PCIE power +12V1@18A, +12V2@18A. Is this 18+18=36A? or I need two separate 36A rails.

The card wants:
Minimum of a 500 Watt power supply.
(Minimum recommended power supply with +12 Volt current rating of 36 Amp Amps.)
Two available 6-pin Molex hard drive power dongles

I also tried with my second power supply and the same thing happen.

Any help will be greatly appreciated!

It sounds like a faulty graphics card. Although the two rails may not be enough while at load, it should have no problem giving it enough juice to boot up.

Thanks for the quick response Andrew!
Hm..strangely..windows just turns on with the card in now...after a couple of hours. I'm installing the drivers now and will restart to see what happens next. But am I right about the Amps? When it says minimum requirement is 36Amps, is it the combination of the two 18Amps cords to make it 36Amps?

I read a section about power supplies before but I am still a bit confused about all these Amps, volts, and watts.

It actually does deliver 36 amps.

Amps = Watts / Volts

432W / 12V = 36A

Your power supply should have no problem powering the card, assuming that no components are faulty. Andrew is right when it comes to your PSU being capable of delivering up to 36A on the 12V line.

It might have been that your graphic card wasn't seating properly in the PCI-Express 16x slot.
