    Post PSU Stress Test

    Hey I am putting in together an mp3 player for my truck and I have a 230 Watt AT Power supply and was wanting to know how much that I might be able to hook up to this without killing it.
    Currently I have a CDrom, 27GB, 40GB, fan for the heatsink, and powering the mobo running a 166MMX underclocked to 133. I need to see about adding an extra fan for more ventalation. Suppose I could add an 80mm or 92mm with out too much of a problem?

    you car run your fans from dc 12v straight from the car. Not that they draw much current, but every little bit helps

    Or he can get an AT style psu from arise if his mb is AT. Notice all the gadget my box has and everything is powered by that small 65watt arise psu.
    BTW, mike, i just noticed your sig said you are still running c2, have u tried c3.

    230W supply will run 3 times what you currently have, I wouldn't worry about it at all.

    Question

    Just a question, why is your CPU underclocked?

    my guess would be that he wanted to use less power, and if all you're playing is MP3s then P133 will do you just fine.

    Well actually, its underclocked by mistake. Its an older mobo, and trying to find the right jumper settings for the FSB is a little tricky some times. But as Telek mentioned it is using less power. My only fear was hooking up the HD's and CD-Rom and worry about overloading the PSU.

    As of right now, the PSU only has 3 Molex type connectors and as of right now they are all in use. Thats why I was a little worried about adding more load to the PSU.

    To give you an idea, I'm running a 1.4Ghz Athlon, 2 7200rpm hard drives, a burner, a cdrom, sound blaster 128, ethernet, tv capture card, ATI AiW 128, all off a 200W power supply and I don't think I've even taxed it. I've had that setup with 4 hard drives plugged in and ran without a problem.

    So I think your 133 with a 220W PS is in no danger

    I don't think it is a bad idea at all to underclock your cpu. You can save several watts doing so. I had a 233 underclocked to 133 until someone stole it. The laptop power supplies I was useing didn't get hot after that.
