    Will this PSU cope?

    So I just purchased the Corsair H70 liquid cooling unit and the Gainward GS GLH 1GB GTX460. I also have a E7500 sitting around which I think I will swap for my E6300, as well as swapping the stuff I just bought with the current setup I have in my system which can be found over in the left there.

    Along with all that I have 4 x 80mm and 2 x 120mm fans all running through my Zalman fan controller.

    So as the titles says, will my current HX520W Corsair PSU be able to handle the GTX460, H70 and the E7500 upgrade? Keeping in mind I am going to try and get the E7500 as close to 4Ghz as possible. Or am I looking at overloading it and possibly breaking some stuff in the process?

    Not trying to be too stingy with cash at the moment (considering I just bought the new card) but ideally if I can hang onto my HX520 for this last minor upgrade before my next PC (probably sometime next year) then I will.

    Your opinions and answers please

    Yes. Even,an HX450W can handle a card like an HD4890 1GB and a CPU like a Phenom II X2 550BE.

    HX520 can cope with a quad core rig easy.

    Re: Will this PSU cope?

    So I am no going to be overloading the +12v rail then with the extra stuff I am putting in? Have done a bit of reading and people seem to say it doesn't really matter about the Watt's but more the strain on the +12v rail? Not too sure I understand all that though.

    Re: Will this PSU cope?

    A rig like yours probably won't pull more than about 300W maximum across all PSU rails. According to a quick google the HX520W can provide up to 480W across the 12V rails, so I don't think you'll have any problems

    If you look at the numbers on the sicker on the PSU it'll list the different voltages and amp it con support on each

    Basically what's going on inside the PSU is it's taking in AC current from the wall, turning it into DC then regulating it into the seperate voltages.
    The "rails" are the sectioons that are taking the DC and regulating it into a specific voltage, each rail is responsable for one voltage.

    Ok I'll admit that very simplified and many different psu's do things in different ways.

    Re: Will this PSU cope?

    I have an HX520 with an i5 750 @ 3.5GHz and an XFX 5850 Black (OC). It rarely draws more than 250w.

    It will be fine with what you want.

    Re: Will this PSU cope?

    Thanks guys, was just getting a bit nervous after I used one of those online PSU calculators and they came up saying I was already drawing like 480W. I know those things are not 100% accurate but thought it would at least give me a scale of where I am at.
