How important is a good PSU?

I know a good PSU is essential to good system health, but do I need to drop the extra cash to replace the PSU that comes with my case if I'm not overclocking? This is the PSU that comes with my case (the Aspire X-Navigator), and while Aspire isn't known for their power supplies, is there any problem with it that I should know? Appearantly it delivers 12V a little low, but within 5% or so. Will that matter? I just don''t want to kill my shiny components.

what is the case that UR getting??
 
Cool-looking PSU, much nicer and more powerful than what came with my Aspire X-Infinity. However, I never hooked the supplied PSU up to my mobo, I ripped it right out and pushed in my trusty old Enermax.

But the Aspire case I got had two dead LEDs, and another died two weeks ago. I wrote a review for the case when I first got it, then realized newegg didn't publish it. So after the recent LED death, I wrote another review, with a lower score...I didn't say anything nasty, but I also didn't praise the fast shipping and great service from newegg, so maybe that's why I didn't get my review published again.

Anyway, considering it pushes 500W, you should be OK for a system that you will not overclock, and one which you will not impede airflow. It should especially be OK for an AMD system. But if you're looking for rock-solid stability, consider looking at an Enermax or Antec.
 
Just assume that it has 3/4 (I made up that number, but just less in general) of the rated wattage and don't push it too hard (ie if you're getting a 6800 ultra, of course if you were getting one I doubt you'd be getting an aspire case and psu).

3/4? Heck. I go with 1/2 if you're talking about a cheap power supply, being that they're rated at 20C.

Insufficient power can cause the most sporadic problems in a PC. Memory related. CPU related. It's the one item I don't like to cheap out on simply because the problems caused by them are the hardest to troubleshoot.


 
If it aint broke, don't fix it. Monitor the system for instability. If there is a PSU issue the system will likely reset occasionally under heavy load
after a while. Also if you seem to get poor drive performance.
