Hi
I'd like to get a new PSU because the one I have is really noisy. I rebuilt my pc last July because the mobo blew so I now have a different mobo and a faster CPU, but the PSU is the still the same. I'm wondering if maybe it's the wrong wattage for my pc now. I think it's 350 watt.
I have an MSI KM4M-V mobo with an athlon 3000 XP CPU. Also 2 hard drives, 2 cd drives, graphics card and sound card (don't know if this stuff is relevant). What power of PSU do I want to get for my pc? Also does anyone know of a good value silent model, or what dB range is I should look out for?

I have had good luck with the Thermotake TR2 430 watt PS. Its a middle of the road PS that seems to be better than the others. I find it quiet enough but it does have 2 80mm fans so its not whisper quiet at all.

I got a 650W £90 PSU from ebay. Though you can buy 500W to 650W PSUs on ebuyer (www.ebuyer.co.uk(or.com)) which I am using in my Media Center. Worth just paying out on a cheap high wattage PSU really.

I'm hoping for something much cheaper than £90. I actually buy a lot of things for my pc from ebuyer (UK). What I'm trying to establish is what wattage I need. Or does it not matter? I dont really understand how it works but I was assuming I would have to go for a specific wattage to work with my pc.

Ok here's what I bought. http://www.tekheads....?product=603272
Got the unit today and fitted it. It's a very sexy piece of kit and it does seem to be quieter. However, my pc is still not as quiet as I'd hoped. I turned it on for a moment with the cpu fan unplugged and it was much quieter so it seems that the cpu fan is the noisey culpret.
I bought a silent one last summer and fitted it because the cpu fan that was in wasn't turning properly and my pc was crashing. However my mobo and cpu died about 2 weeks after fitting the new fan and to this day I'm not sure if it died because I fitted the fan wrong or if it was just dying anyway.
So, I had to get a new mobo and cpu and just stuck with the fan that came with the new cpu and so I still have the spare silent fan that was on my old cpu for 2 weeks, sitting in a box. Do you think I should dare fit it again or is this a professional job that I should take to a specialist?

If you only replaced the fan and did not take the heatsink off the processor it should not cause a meltdown. The fan was spinning i assume. If you did pull the heatsink off the processor you needed to clean the processor with alcohol and reapply thermal paste to get a good surface connection between the 2. Also be careful of quiet fans since many are quieter because they run at slower speeds and less CFM(cubic feet per minute). This can cause overheating and burning of the processor. i look at airflows, then fan speeds, and third DB noise when buying a fan. I would prefer more air at lower speeds to get the same or lower Db result. I also usually will replace 80 mm fans with 92 mm fans with adapters.

Heres why. I like vantec thermoflow fans for processors because some motherboards will speed up the fan when needed but slow it back down when temps are lower( using the computer less). A 80 mm vantec delivers 23.8 to 41.6 cfm at speeds from 1950 to 3400 rpm. The same fan in 92mm delivers 34.8 to 58.5 at speeds of 1850 to 3100. So the larger fan blows more air at slower speeds thus making it quieter. The one difference is the 92 mm is louder by 3.5 Db thruout its range. I still can tell they are quieter by my ear simply because they do not have to run up in speed and more air is getting thru. The adapter slows the air flow only slightly.

I had this beauty from Overclockers. It is nice and quite and a 580 Watts. It is in my opinion a cheap price for decent PSU.
All the best.
