Hi guys. I bought an AGP EVGA Geforce 6600GT 128-A8-N350 from newegg a few months ago. After installing it, I was experiencing very sharp graphical glitches (particularly with lighting), frequent slowdowns, and very low performance benchmarks.

I posted about it on the NVIDIA tech forums, and the only responses I got seemed to point to the power supply. I have some generic 450 watt power supply that came with my case a couple years ago, it's probably not great but it's never been a cause of problem before. They say I need a power supply with more amps on the 12v rail, but then other people claiming to be electricians say I don't. Furthermore, when I look at power supplies on the market, /very few/ actually have the amount of amps they tell me I need. How is it that such a massively marketed card could have such a requirement that appears to be so uncommon?

I've spoken to many people with cheaper, older, power supplies than me who are happy with their 6600GT. I am very worried that even if I bought a better power supply and took the time to install it my problems would not be resolved. I have tried underclocking the card and enabling its temperature monitor, which seemed to be normal. I don't believe there are many power hungry devices in my computer.

Is there any more advice you can give me? Thanks.

All I can think of is to make sure you have the latest drivers (version 84.something now). If you want more PSU info, go here: The Truth about PSU power ratings

I've got the 6800GT, and it runs fine on my 450W PSU which was whatever brand came with my case.
