Ultra LSP750 750-Watt is enough for a zotac 660ti amp edition?

hi guys

i have a big doubt, I going to buy a new Gpu Zotac GeForce GTX 660 Ti AMP Edition and the Minimum PSU Requirement is 600 Watt but I don't know if my PSU Ultra LSP750 750-Watt is enough for working correctly with this zotac amp edition and the whole system? because some people say that psu only have 500w real and not 750w its true or false?

Current System:
CPU: intel core 2 quad Q8400 2.6 GHZ
RAM: 4gb DDR2 800mhz
HDD: Seagate Barracuda 2TB 7200RPM ST2000DM001-9YN164
Samsung HD501LJ 500gb 7200RPM
PSU: Ultra LSP750 750-Watt

this PSU will work for a new gpu's changes or build a new system?

i hope you help me , regards ;)

  1. In any case 500watts would be enough. Those people are somewhat right about that PSU being low budget and not very good.
  2. I bought this PSU in 2010

    zotac recommendation

    Zotac GeForce GTX 660 Ti AMP
    600 watt power supply recommended
    190 watt max power consumption

    I am scared if I buy this card and don't working in my pc for this PSU and need it buying another :??: because I have only the budget for this video card

    what would you recommend me?
  3. I would go ahead and get the card the PSU will drive it but think about getting a better quality unit in the future. The card only needs 450watt PSU http://www.realhardtechx.com/index_archivos/Page362.htm
  4. For a system using a single GeForce GTX 660 Ti graphics card NVIDIA specifies a minimum of a 450 Watt or greater system power supply that has a maximum combined +12 Volt continuous current rating of 24 Amps or greater and that has at least two 6-pin PCI Express supplementary power connectors.

    Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Total Combined Continuous Power/Current Available on the +12V Rail(s) rated at 45°C - 50°C ambient temperature, is the most important factor.

    Overclocking of the CPU and/or GPU(s) will require an additional increase to the maximum combined +12 Volt continuous current ratings, recommended above, to meet the increase in power required for the overclock. The additional amount required will depend on the magnitude of the overclock being attempted.

    The Ultra LSP750 750-Watt Power Supply (ULT-LSP750), with its maximum combined +12 Volt continuous current rating of 45 Amps and with one 6-pin and one (6+2)-pin PCI Express supplementary power connectors, is way more than sufficient to power your system configuration with a single GeForce GTX 660 Ti graphics card.

    It's not considered a very reliable power supply unit though. It looks like it's based on an older discontinued Andyson 700 Watt platform.
  5. I using my system only for a normal tasks in windows and playing pc games and emulators and not using it for SLI , overclocking or something like that

    thanks for the support pals for solve my doubts normally and technically
    now It's very clear for me
