Can weak power supply cause errors in Prime95?

I've been trying to overclock my amd 64 3200+ and am having problems. Whenever I try to overclock I run into problems at around 2300+ mhz (stock: 2200 MHz). Basically I start getting Prime95 errors. I have tried everything from changing memory, increasing voltage a bit to the cpu and memory, and even changing the HTT from 4 to 3 or even 2 to see if it would make a difference. It still either freezes, gets errors in Prime 95, or even reboots during start up. I know temperature is not a problem since it is running between 42 - 49 during heavy load, which shouldn't be a problem.

I am beginning to think it's my Power Supply or I just got a cpu that can't overclock well. My +5V is at 4.92 and my +12v is at 11.46, which I believe is low. Any recommendations?

Did you actually physically get those voltage readings? Or are you getting that from some kind of motherboard monitor? Motherboard sensors are often quite wrong, so you need to check the rails with a multimeter.

The True 480 is a very good PSU. And to answer your question, yes a bad PSU can cause errors in Prime.
 
Also, remember overclocking is a luck of the draw type of thing. Some chips will not be able to go much faster than stock if your unlucky. Just because someone gets a 40% overclock with a chip doesn't mean you'll have the same results.
My vid card is an example. I've got a geforce ti4200 8x and if i push it even a few mhz faster, it artifacts like crazy. I've tried different cooling solutions, but nothing. Just bad luck.
