    strange noise and burning smell from PSU


    Hi,
    I have a backup pc with the following hardware:

    CPU: Intel Core 2 Duo E6300 @3,0 GHz
    RAM: 4,5 GB DDR2 Dual Channel @856 MHz
    Motherboard: Asus P5Q Pro
    GPU: Ati Radeon HD 4870 X2 @800MHz/1000MHz
    HDD: 200GB @7200rpm
    2 case fans, power leds, 2xDVDs ROM

    Powered by a NILOX 600W PSU.

    Since I changed my GPU (from a GeForce GTS 450 to an HD 4870 X2), I noticed that my PSU makes a strange noise (similar to an electrical "beep") when i use games or other applications which make the GPU work at high performance.

    Today I launched GPU-Z's render test in fullscreen mode, and after 5 minutes, hearing the "beep" from the PSU, I also noticed that it was really hot and I noticed a light burning smell. Immediatly I turned off my pc.

    What should I do now? Should I replace the PSU with a new and better one? I don't want to burn my pc
    (the PSU has got only 22A at 12V)

    That PSU is horrible.. no offense. I would have -never- trusted that GPU to such a weak PSU. I was barely able to find information about it online.

    Change it asap.

    Yeah, I noticed it now.. It should explain also the high CPU and GPU temps in idle...
    Please can you suggest me a good PSU for this pc?

    Personally I like seasonic.. their 560W model is great. Modular and gold certified.
    But I believe even a Cooler Mater 80+ bronze PSU would work for you if you do not want to spend as much.
    The silent series is really good for a budget from what I've read.

    You would need to calculate yourself.
    There are plenty of wattage calculators online. But it should not be more than 500W with a REPUTABLE PSU.

    The 4870 X2 uses a 6 pin PCI-E power connector plus an 8 pin one. That makes it a high-powered card (as much as 300W, all by itself).

    Sapphire recommends at least a 650W PSU:

    SAPPHIRE ATOMIC HD 4870 X2 2G GDDR5 PCI-E#

    They don't list a +12V current requirement, but I'd guess you'd want at least 40A. (A Corsair HX650 is rated at 54A at +12V.)

    Is that Nilox PSU really rated at 22A at +12V? There are 300W power supplies that are rated above that. It would still be less than great if it has two +12V rails, with 22A each.

    First of all, let me ask..........do you actually need that graphics card in a backup computer? If it is absolutely necessary, I would go with this Corsair AX750 or the SeaSonic X750 equivalent, whichever you can get cheaper.
