    Hi I have a problem when I stress my computer ( both gfx and cpu ) example 3dmark
    I get a whineing noise from my psu. It has been that way all since I changed my gfx from a 9800 se to a x800 xl ....
    The psu is a 350W:
    single 12V rail @ 18A
    3,3V @ 28A
    5V @ 40A

    I heard it could have something to do with a filter in my psu :confused:
    Can I fix it? Is it dangerous? If i can´t fix it what´s the best powersupply for <100€ I can get?

    You may need to up the wattage a bit, also go for a bit more amperage on the 12v line.

    it could be that the sensor in your psu for the fan is acctivating when the psu gets hot (when running 3dmark) so maybe a noisy fan because eating more power for the gfx card?

    Can you list all your hardware, I mean everything down to usb printer if you have one. Then we can see how much juice you are using and how much you may need.

    Cheers

    I get a little over 350 watts your using at the momment, go for a good quality 400 - 500w supply with plenty amperage on the 12v line and youll be fine.

    I dont think so ,I recognize fan noise (I have plenty, and I tried switching the fan to full constantly). Can you think of anything else it could be ?
    The sound is high frequent.... Dont know how to explain it...

    I guess they just don't make Power supplies like they used to. So many PSUs seem to last only half a year to maybe two. I have a 75 watt from a computer that is nearly eight years old. The computer has been booted up nearly everyday since I bought it, and I have never had a single problem. I guess it could just be that higher performance parts just don't last as long though.

    I had that also, I cupped my hand over the rear power supply fan for like 5 minutes and haven't had a problem since, I felt like Moses.. :laugh:
