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)
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)
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.
