I built a PC a few months ago (Athlon XP 3000, Asus A7N8X Deluxe, Radeon 9800 Pro, Asus CD Burner) that is being powered by a 300 Watt power supply.

I was telling a friend who builds PCs for a living this the other day and he told me that I probably wasn't getting the most performance out of my PC because it was underpowered. He recommended a 400 or 450 Watt supply and told me that it would be quite a noticable difference.

This was the first time I've heard of this kind of thing, is there any truth to it?

300W for that system is definately cutting it close. Systems that are strained for power are generally very unstable. I agree with his recommendation for a 400-450W power supply, just make sure you buy from a quality manufacturer such as Antec, Fortron, or Enermax.

I haven't noticed any stability problems, but that's good info anyway. Thanks.

Your friend knows too little about computers to be giving advice! Lack of power causes glitches/stability problems. If you're not experiencing these, you have enough power, and adding more has no affect on performance.

it just might actually... when I went from 300w to 600w I experienced faster hdd, ram and graphics. Had no instabillities before I switched... just felt like going to the top before installing as many fans as I could possibly mount in my system =). Didn't get around to buy the fans yet though... long live a blocked VISA-card
