    Quietest power supply around?

    Fed up with the storm in my studio!
    Got a Zalman CPU cooler, very quiet, now I need a quiet PSU to go with it.
    I'm looking at Zalman, Enermax, Nexus NX-3500.....

    Any advise appreciated!

    I recently built a machine (Athlon 64 3200+, CDRW and CD, 2 hard drives and ATi Radeon 9200 SE graphics) and the Enermax Noisetaker 325 watt PS is plenty. It's not silent, but compares well with my other quiet power supplies. It's a variable speed PS so if it heats up it'll throttle up the fan to cool off, but I've never heard it do that. At about $50 it's a great deal.

    Silenx is the way to go. Products range from practically inaudible to dead silent at 0db. http://www.silenx.com You can buy them about anywhere.

    Coolmax also has a line of fanless power supplies. I recently purchased a CF-400 (400 watts) and I'm quiet pleased with it. They're not cheap though (~$140). For details on the various models see:

    http://www.coolmaxusa.com/products_p...ly.asp?item=28

    Silenx is good too, but Coolmax products may be more widely available. And unlike Silenx, Coolmax fanless supplies do not have a big heatsink that sticks out the rear.

    I also like the Antec "Truepower" series supplies, which do have fans but are very quiet. They're ~$100. However I would avoid all other series of Antec power supplies.

    Hope this helps,

    Re: Quietest power supply around?

    I finally built an almost silent pc -- Antec Sonata case w/truepower, Zalman CPU cooler, ASUS P4P800-SE motherboard, and Seagate ST3120022A UltraIDE 120GB disks, Intel 3.0GHz cpu (prescott on this one, though I think I prefer Northwood). For the first time ever in a long history of computers, I can have it in the same room with me, and not banish it to a closet with a snakesnest of cables.

    Other tries (still in my closet) have used ASUS P4C800-E deluxe and ASUS P4C800 Deluxe motherboards, both of which somehow run the fans enough faster that the noise is still annoying, even in a Sonata case; and WD Raptor disks, also loud enough to be annoying; and the intel factory cpu fans, also too loud.

    The top rated 400W+ power supply at silentpcreview.com is the Seasonic SiperSilencer 400. I just got mine last week and it's amazingly quiet. You can hardly tell that the fan is moving. Even when powering my overclocked A64 3000+, it hardly moves any air, yet its case stays cold to the touch. Amazing. I got mine at newegg.com, but Frys also carries it. About $90.

    I ran the highly rated Fortron 300W supply for a few years, and the Seasonic pummels it.

    OK you're where I'm at: p4p800 delux; silenx power supply; but the fan on the intel 3ghz is unbelievably noisy, and also appears to flux a bit in speed when demands are put on it. The dealer says you can't substitute anything for the cpu fan..

    So he's wrong. What can I use as a substitute that's dead quiet?

    BTW, my silenx doesn't push a lot of air, and the box (which contains thrive hard drives) seems too warm to me. But that's another issue.

    i would look forward to get the zalman cnps 7000, it is a really quiet cooler and you can turn it down to move slower, you will never need the full power of the cooler because he is so big.

    Re: Quietest power supply around?

    Just spoke with the dealer. He says to get a really quiet cpu cooler I should spend 179 Can on a water cooling system.

    Any experience with that? Is it transferrable to other cpus?
