    Can my PSU cope? Is 12V Rail at 12.65V dangerous?

    Just upgraded to dual core 4400+ X2 110W version... This probably uses more power than my old operton 152... Can my PSU take it?

    Just noticed this 12V rail too... Is it a sign that my psu is struggling?


    <-- see system spec

    Re: Can my PSU cope? Is 12V Rail at 12.65V dangerous?

    Your PSU is an Xclio 480W yes? I wouldn't really trust that to give out 480W consistently. I think 12.65v on your 12v rail is OK however the 3.3v line giving out 1.54v looks a little low.

    If you can afford it I would recommend the Corsair 520W HX modular PSU. I bought one from Scan in October 2007 when my Hiper 580W went KABOOM.

    Computer hardware and software at amazing prices, available online from Scan Computers UK

    Excellent price and it copes with my PC OK. It is also modular so you can reduce on a bit of clutter within your case but then seeing you have 2.5Tb of storage space perhaps not.

    I've got a 480 watt xilence running all my gear and it's fine Think you'll be alright with your PSU, you've got a more power hungry GFX card than I have too.

    Its probably reading your 12V wrong.

    Re: Can my PSU cope? Is 12V Rail at 12.65V dangerous?

    Yup its a 480W Xclio... I am thinking a dual core, a 9800gtx, 5 hard drives and load of usb devices might be too much for it... I don't have a multimeter...

    The 3.3V is exactly 3.3V in everest and bios... the 12V doesn't come up in everest/bios... is there another voltage checking program that I can use?

    Just buy any old cheap multimeter. Forget about software options if you want a reading you can trust.

    Re: Can my PSU cope? Is 12V Rail at 12.65V dangerous?

    AFIK non of the voltage sensors/software on a mobo is calibrated - so the readings are suspect from the word go. If they are 10&#37; accurate, its probably as good as it gets. Is it working? Yes - don't worry. If it isn't - start doing some investigating with a multimeter in the back of the ps connectors - but be careful you don't cause damage by careless probing and shorting something out.

    Bottom line - "If it ain't broke - don't fix it"!

    Well it is working fine and all the other voltages are stable and correct so I'll leave it

    The 9800gtx is coming out soon anyway and this is becoming a htpc

    Thanks guys

    Re: Can my PSU cope? Is 12V Rail at 12.65V dangerous?

    my xclio is fine, the 12v rail hits 11.9 on load but thats it and with the 3.3v going to 3.23 and 5v staying the same. Speed fan says that my -12v is 16.7 ansd my -5v is 8.6

    The readings are wrong, simple as.

    Measure with a multimeter to check. There is no way that your +5 rail is at that, so it stands a good chance the +12 rail isn't correct either

    Re: Can my PSU cope? Is 12V Rail at 12.65V dangerous?

    A PSU isnt likely to overvolt a rail, its most likely to undervolt it under load.

    how would you go about finding/testing the 12v rail (well 4 on my xclio xD) because im curious as to what volts mine are doing.

    iirc XClios are CWT built so OK.
    & 12.54V is (just) within the ATX spec. of 5% tolerance.
