So when I look through it's requirements, it states that they recommend at least a 500w PSU with 2 6 pin connectors free. When I opened up my unit, I only have a 400W supply with a maximum 300W to the 12v which I assume is what the 6 pin is. I also only had one (1) 6 pin connector available. I'm not a tech guru here, still learning so I'm asking this to make sure I don't blow the card up or something.
My questions are:
Do I need to have both 6 pin connectors for the unit? Right now it's running on just the one.
Will it damage the graphics card by having either the lower PSU and/or only using one 6 pin connector.
I have no problem upgrading the power supply and if I must I will take this new card out and wait until I buy a new PSU for it.
Here is my dxdiag report if this will help:

Well I feel silly now, actually I thought it had started up, I was wrong.
I was actually using the on board motherboard graphics so that clued me in that it wasn't enough. So I shut it off last night and this morning will go pick up a new power supply. Thanks for the answer though. I was planning on ordering one online as you can get em cheaper usually, but I guess I will go to Micro Center and the few extra bucks.

Get no less than the CX 500 but i would recommend 600w+ so you don't have to get a new PSU the next time you upgrade your GPU

I picked up a CX600M power supply. Got another problem now though. Not getting any video signal from the computer to the monitor. Don't know what is up right now. Everything is booted up and running far as I can tell.
I completely cleaned out my computer as well. But the guy at the store said to get my heat sink off I had to get at the back of my motherboard. Opened up the other side of the computer and it's a solid metal sheet so I took the motherboard physically off. Still no screws to remove. I put it back on and locked it down and just carefully got in between the fins of the heat sink. Got the power supply in and set it all up.
Not quite sure what to do right now. Maybe will take out the new graphics card and see if that is somehow interfering.

Ok, now I'm stuck. I took the new video card out and suddenly I have a signal again to the computer monitor. So I reseat the card and plug it back in and again, poof no signal to the monitor. Not sure what to do here, never installed a video card before and not gotten a signal.
Ok, update. Took my DVI cable and put it directly into the video card spot and I got a signal, but directly into the motherboard spot and I get nothing. Problem is on my 40 inch tv I have no connection for the DVI, but I do have hmdi connections so will have to try that and hope it looks good. On my old video card it looked horrible.

If you plug it into the motherboard it will use the on board GPU not the dedicated one. You figure out your own problem so now all you have to do is get an hdmi cable and your set.

Yeah, I already had a HMDI cable as my old video card supported that option as well. But my old video card didn't override the motherboard graphics for them monitor when I had the cable between the motherboard and the TV. For some reason, with the new video card in I must connect directly to the video card to receive a signal. Unfortunately, like the last card, the HDMI cable's view isn't very good with text. It's readable, but not sharp at all. It makes no sense to me why I can can hook up to the motherboard and use the pc input and have crystal clear text, but I use the HDMI port and the text gets kind of fuzzy looking.
I've tried looking around but it seems this is fairly standard with an HDMI cable at this point, just doesn't make sense to me why.
