I just got an Nvidia Geforce GFX 260 -

The specs say that the minimum power requirement is 500W.

When I plug in my gfx card, the computer boots up - I don't hear any 'abnormal' BIOS beeps, but my monitor doesn't come on.

How do I know if my system has enough power to send to the GFX card?

Or rather...does this sound like what would happen if the GFX card is not getting enough power?

I have maxed out my RAM slots - 6GB over 4 slots. I have 2 hard drives, 2 DVD Drives, 1 Network Card, and 1 USB expansion card.

Suffice it to say, I am using up a lot of the power from the if it is that I don't have enough power, I wouldn't be surprised.


P.S. For what it's worth, the card only has 2 DVI outputs and I only have a VGA monitor - so I got a DVI-to-VGA adapter. I doubt that would cause this issue, but figured I would throw it in there just in case there is some strange quirk that I don't know about.

If you don't have enough power, it is likely that your system would shut off instantly. Since when you don't have enough power, you don't have enough power for all components. Are you sure you connected all required power connectors to the card? – Oliver Salzburg Jun 22 '13 at 0:25
However, in this context, it would also be interesting which wattage your PSU has :) – Oliver Salzburg Jun 22 '13 at 0:28
I think I did. Either way, I took it out and reseated the card and it has worked. If you write that as an answer, I will accept it :) – marcamillion Jun 22 '13 at 2:11
If you were able to fix your problem yourself, you can also write your own answer and accept it as the solution :) – Oliver Salzburg Jun 22 '13 at 15:44

I simply re-seated the GFX card and it works fine now.
