Well thanks for all the responses everyone, very very much appreciated. Judging by all the responses, you've all made it perfectly clear to me, that I'm going to need a new power supply, that is, if my new graphics card is going to still be useful in a few years. The search, is what has taken me sooo long to get back to you all. Sorry about that.
Anyhow, I've found a 400 watt power supply that I think can be squeezed into my box, even though I might have to use a persuader on the case { a hammer }. I was hoping someone might share their wisdom on what other items I might need to purchase, as I really do live in the middle of nowhere and will be ordering everything from very far away.
The power supply is this one:
Athena Power AP-MPS3ATX40 400W ATX12V
I found it on the newegg.ca website.
Thanks a lot in advance, I look forward to your thoughts. Peace everyone and enjoy your day.
