    Question Power supply help

    I am finally going to upgrade my aged PIII system to something more modern. I have not yet decided wether to go intel or amd as the stuff I do has +'s & -'s whichever route I decide to go.

    But I did get my hard drives in. Two 120GB SATA Seagate's that I'll be using in RAID0. I looked at their power connector.... and said chit, more stuff I gotta buy.

    While I am a heavy OC'er (my PIII 1.1GHz is @ 1.496GHz). I am very picky when it comes to noise levels. Using a sound meter from 3 feet away, my current setup is 26bs. I find that a little more than what I like and do not expect a new system to be quieter. But if possible I would like to keep it at the same noise levels if not lower.

    So I am shopping around for a power supply that has SATA power connectors and is quiet. Any of you have any suggestions?

    Judging by how much noise my Zalman fan makes (with exact specs on the net) I would say

    my Antec 480W TP should be within your specs, especially if you have cool enaugh case so bottom fan doesnt get too much of a workout

    I'm not aware of any inbuilt SATA power connectors. You just use adapters. The best noise reduction for any PC is to wire the fan for 5V operation. Maybe even get a quiet fan and run that at 5V. The PSU will be a little warmer but this is ok.

    above mentioned Antec 480 True power has built in SATA power connectors (at least my revision has them)

    I thank you much for the replies , took me a little while to find out that people replied to my thread as my spam filter is zapping my email noticications

    One more thing, which of the models listed has strong amperage on the 12V rail? I do not want to get a 'high watt rated' PSU and find that it lacks the amps on the 12V rail. I want at least 25A... more the marrier
    (just from designing 'noisy' systems I built for other people. Without a good amprage on the 12v rail, they could never OC that well.)

    Thanks again for your input. If need be I can swap out the fans from a PSU and put in some L1A's, or Stealths. But I kinda want to avoid that as it voids the warranty.

    Even a 430w Antec Tru Power would likely work just fine. They have 2 SATA power connectors. The power supply has 2 thermally controlled fans that are VERY quiet. They generally run at about 1600rpm. There is also a special fan header so you can hook other case fans up to this thermal controll. The specs on the 430w are as follows:

    +5V@36A
    +3.3V@28A
    +12V@20A
    -5V@0.5A
    -12V@1A
    +5VSB@2A

    http://www.antec-inc.com/specs/true430_spe.html

    That is 240w for 12v. They also state a maximum of 410w for +12, +5, and +3.3. This should do just fine. NewEgg carries them for about $70.
