I am looking to upgrade my graphics card and am looking at the higher end agp cards. My question is I have a 460w power supply and the min requirements say you need at least 450w, will my cpu be able to handle it? It seems like everything I read says to have 500w.

Here, eXtreme Power Supply Calculator v2.5: http://www.extreme.outervision.com/psucalculator.jsp
Be sure to get a well known power supply brand. I like Antec.

Not just a well known brand but a quality series in a well know brand. Coolermaster and Antec are good brands but I wouldn't trust an eXtremepower or a Basiq series as far as I could throw it...

Be careful not to mix up QTechnology and Q-Tec/QTech. They're not the same company.

QTechnology make nice quiet PSUs. Q-Tec/QTech makes noisy garbage.

I actually have 2 DVD RW drives instead of one, an LED Light, an internal fan, a larger fan in the back, the power supply fan, 6 usb ports, and I think thats it. My question is can I run an ATI 1950xt agp that recomends 450w on my 460w psu? Thank you for your help!

That seems low. Are you sure you filled everything out including "Capacitor Aging".

If you are unsure of anything then take a look at the bottom of the page for definitions.

How many Amps are on your 12V rails? Which card do you plan on purchasing?
Also whatever that calculator provides I always recommend 100W above what it suggests, you simply need head room and consider capacitor aging as the efficacy drops. Also, note that if you 420W PSU only has an efficiency of 70%, then your PSU will only deliver 294W as the other 30% turns into heat output when the PSU converts the electricity from DC to AC.
