To start off, I have a very bare bones desktop. And had only planned to upgrade my graphics processor to an eVGA 8600GT.

AMD Athlon 64 Processor 3500+, 2.21GHz (Socket 939)
1 Gigabyte DDR PC3200 (two sticks of 512MB)
nVidia 6100

As you can see, a tad wimpy, but will suit my needs for the games I am receiving soon (with the 8600GT, of course). Anyway, the PSU. My power supply is that of a 300w. As far as I can tell, it has +12v on 15a with a PCI-E connector (which I wouldn't need for the card I am going to buy). I'm not entirely sure if it can handle the 8600GT, but I figured out that the 8600GT only draws a max power of 43 watts. I'm just a little worried, what's MOST LIKELY to happen? Will the card underclock? Or fry anything in my desktop?

One SATA HDD, 200GB
Five USB Ports (will be using one during gaming)
80mm Fan
DVD+-RW Dual Layer Optical Drive
Not entirely sure on the heatsink, if that matters..

I am sort of willing to risk it, but not really sure. Also, by now you may be asking why don't I get both. I can't. I recently quitted my job and only have enough for a card, so it would take me a few weeks to scrounge up some money for a PSU. And about that Power Supply Calculator, is it really accurate? I sort of tried it and played around with it coming to a total 190w.

The only things I totally wasn't sure of were the 56k PCI Modem, Sound Blasters, TV tuners, etc., and also the water coolings. So if someone is willing to help me with that, that'd be nice.

In short, TL;DR could I run the 8600GT on my 300w PSU temporarily (on a very basic computer) for a few weeks until I can come up with the amount of money needed?

PS. If this matters, I have owned the computer for 2 years. And did add it in to the PSU calculator which came to an average of 250w with a >30% capacitor aging.

It looks like the minimum suggested PSU is 325W, I wouldn't try running that card on you 300W PSU.

Unless you are going to be overclocking I don't see any reason that you would need liquid cooling.

Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.

Oh, alright..

Well, just in case anyone else has anymore opinions, here's my PSU sticker:

As you can see, it has a max output of 288w, which would come to 24.xx amps I believe, but it does not have dual rails.

Anyway, this is the PSU I was going to get. Looks nice, cheap, and is from Antec:

It does have dual rails (mine doesn't), but it only goes at an amperage of +12v1 on 13a and +12v2 on 10a. The max output is 276w I believe, which would be 23 amps. I'm not entirely sure if it would be good enough because of it being a little bit low on the dual rails.

Well...why would you risk running an underpowered PS, which is the most important part of the system, since nothing works without it?

It's not like there is a shortage of other PSes that would do the job...at a reasonable cost.

Oh, well...

You're 12V rail only has 15AMP's, I wouldn't consider running much on it.
Programming today is a race between software engineers striving to build bigger and better idiot-proof programs, and the Universe trying to produce bigger and better idiots. So far, the Universe is winning.
