Is 500W really sufficient for C2E and GTX 560 Ti 448?

I'm finally upgrading my computer from my C2D and Radeon HD 2600 and I currently have a 500W power supply. I'm upgrading to a Core 2 Extreme QX6850 with a GeForce GTX 560 Ti 448 and Outervision's extreme power supply calc says that I would only need 499 watts minimum for this setup with one video card.

Does this sound right? I would think it would need 600 to 700 W.

More about 500w sufficient
  1. The EE is only a 130w part. thats what 65w more than a c2d.
    The 560ti is about 150w which is only ~50 more than the hd2600.

    You could probably run the 560Ti on a quality 350w unit, not that I would recommend that. 500w is enough to take into account capacitor aging but I hope you will take into consideration getting a new PSU if yours is 4-5 yrs old. I would hate to see an old PSU suddenly get stressed beyound whats its used to and crap out- taking out the new GPU, and motherbd with it.

    edit - if you plan to overclock then yess add a few hundred watts to the PSU.
  2. What kind of power supply?
  3. It's the ULTRA X-Connect Modular. http://www.extremeoverclocking.com/reviews/cases/Ultra_X-Connect_1.html

    And yeah I've been using it for about 4 to 5 years now.
  4. You should replace that immediately!

    The Ultra X Connect has insufficient PCIe power connectors for a GTX 560ti 448 Core and is of questionable quality. With the advertised 34A on the 12V rail it meets the minimum electrical capacity that I would recommend; but I always recommend using a PSU that has the required PCIe power connectors and avoiding molex adapters. I recommend upgrading to a good quality 500-550W PSU with 36A or more on the 12V and two 75W 6-pin PCIe power connectors. The Antec Neo Eco is a good PSU at a great price of $50 right now: http://www.newegg.com/Product/Product.aspx?Item=N82E16817371030&Tpk=neo%20Eco%20520 It's made by Seasonic and is based on their outstanding S12II-520 PSU. For $10 more I'd go with the Seasonic S12II-520 itself: http://www.newegg.com/Product/Product.aspx?Item=N82E16817151094&Tpk=s12ii%20520 for two more years of warranty.

    Me too
    With the current promo being only a $10 difference, if able to purchase from NE one would have to be really silly not to

  8. That is one vintage power supply. I think the time is now to upgrade.
