Is my power supply good enough for the GTX 560ti?

I have just purchased a EVGAGTX 560 ti and should be at my place in the next few days. I have done all the research in terms of whether it will fit and if I have the right slot kind blah blah blah. I thought I had a 800 watt power supply but as it turns out I only have a 500 watt power supply that has a single 6 pin pci 2.0 power connector. Ya I know, I messed up with the power supply research because the gtx 560 ti specs say that it requires a MINIMUM power supply unit of 500 watts. What I would like to know is the following: Seeing as to how I have the minimum power supply needed, is this fine or is it risky? Would it help if I unplugged the floppy drive in my computer and if so then how much of a difference would it make? Is it bad to use 6 to 4 pin converters that come with the graphics card or is that fine to use? What is the worst that could happen if it turns out my graphics card isn't getting enough power? I ask this because depending on what you guys tell me, I might just try using my current PSU and if all it does is cause my computer to freeze up then obviously I will get a new PSU at that point. However, if you guys tell me that using my current PSU runs the risk of somehow destroying my gtx 560 ti then I will just buy a new PSU right now. If I do need to buy a new PSU, whats a good one to get? Any links you can share with me? Phew, those are all my questions, thanks for listening and answering them!

you should be okay but did you really need to get it.. i mean the 560 oc's well but if your not overclocking an hd 6950 1gb sits at the same price tag and outpreforms it 9/10 and in some of those case the 560 even loses to the 5850 and 6870

Floppy drive? How old is your PC?C_Rule

some folks keep em for nostalgia.. i have one still an antec 900 with a floppy drive.. now youve heard it all :P

When I originally built this rig about 8 years ago, I put a floppy in the case, but never plugged it in. It is still taking a 3.5" drive bay.

So you don't think I'll have any problems with my PSU overheating or somehow damaging my graphics card an any way?

Take out the side of your casing and you should be able to tell the brand of your PSU, that's very important to know...also how old is the PSU? I have heard over the years a PSU loses some power....

Having 2 PCI-E connectors is a good sign but none of the other information helps. Can you take a pic of the PSU and post from BOTH sides? I mean even the lower quality PSU's have a "name"...

500 should be enough if it's a decent quality PSU and you don't have a ton running on it. Some symptoms of problems would be complete system crash when playing a game, the graphics card pushing 90c + constantly at 100% fan, etc.
