Yeah... I think I'm screwed.... my power supply is maximum 500 watts....
specs on the card state: Minimum 550 Watt or greater system power supply with a 12V current rating of 40A (630 Watt or greater recommended for non-SLI and 680 Watt or greater recommended for SLI)
The only things I have in my slots are a low power wireless antenna, and my sound card.
Here is my power supply specs... sorry for the poor photo but you would not believe how I had to contort myself to get in there upside down.
The verdict? I can't afford a new power supply...
If no good with only these power specs I would love to ask what card you would recommend as your #2
