FSP500-70EP on GTX 670

Hey guys, I wanna ask whether my PSU will support a new GTX 670 card. On its +12V rail, the ratings are:

+12V1 @ 14A

+12V2 @ 16A

+12V3 @ 18A

the recommended power supply for GTX 670 is 500W and at least 38 Amps on the +12V rails. What does that mean?

Thanks in advance :D

  1. On the sticker there under the amp rating stating watts divide those by 12 gives you the combined amps. Picture to small for me to read http://www.plugloadsolutions.com/psu_reports/FSP%20TECHNOLOGY_FSP500-70EP_ECOS%202806_500W_Report.pdf only info I found.
    38amps x 12 volt = 456watts needed on the 12 volts.
  2. The FSP500-70EP has a maximum combined +12 Volt continuous current rating of 34 Amps.
  3. what will happen if I place a GTX 670?
  4. It is either going to shut down the system or run.
  5. will it damage the card?
  6. ok, i'm currently thinking about a GTX 660 Ti since the 670 may stress my PSU.

    Anyone has any idea how many amps the 660 Ti requires? and does PSU support it?

    For a system using a single GeForce GTX 670 graphics card NVIDIA specifies a minimum of a 500 Watt or greater power supply that has a combined +12 Volt continuous current rating of 30 Amps or greater and that has at least two 6-pin PCI Express supplementary power connectors.

    Where did you get the 38 Amp requirement from, for the GeForce GTX 670?


    For a system using a single GeForce GTX 660 Ti graphics card NVIDIA specifies a minimum of a 450 Watt or greater power supply that has a combined +12 Volt continuous current rating of 24 Amps or greater and that has at least two 6-pin PCI Express supplementary power connectors.

"When it comes to power, ASUS has retained the NVIDIA reference design requirements and included a an 8+6 pin power connector layout for the GTX680 and a 6+6 pin power connector layout on the GTX 670. ASUS recommends a 500W power supply for the GTX670 and a 550W power supply for the GTX680. Both power supplies should have at least 38Amps on the +12V rails."

    So would you recommend the 670 or 660 Ti, the price difference in my area is around $40-$60

    Too bad LegitReviews.com didn't actually measure the card's actual power consumption.

    Since the ASUS GeForce GTX 670 Direct CU II TOP 2 GB is factory overclocked and ASUS states a Maximum Graphics Card Power of 180 Watts, and techPowerUp.com measured the actual power consumption at 177 Watts during gaming in their review of that specific card, the minimum +12V @ 30 Amps that NVIDIA specifies for the PSU is correct.

    +^1 Agreed!
  11. I see, so my PSU would be able to support the 670 right? Would it be close, I mean is there any chance my system would auto shut down when stressing the card i.e playing games?

    And would you recommend a 660 Ti or 670?

    What are the rest of the components in your computer system? Need to know this to determine what the total power draw on the +12V rail will be.

    If your system is a consumer desktop computer like an Acer, Compaq, Dell, HP, etc. then list its model number.

    Recommending a 660 Ti or 670 will depend on the games you play. List the games.
  13. I have a Acer Aspire M3985

    Games I play include:

    Modern Warefares 2 4 6
    BF3
    Star Craft II
    Red Alert III
    Burnout Paradise


    and probably some MMORPGs not planning to play yet but might in the future, still searching for some good ones :D
  14. Best answer
    Which CPU model did your system come with?

    Core i7-3770
    Core i5-3330
    Core i3-2120

    NVIDIA's PSU power requirements are based on an Intel Core i7-920 CPU which draws at least 2 Amps more from the +12V rail than the Core i7-3770 in the list of CPUs above.

    I would say your current FSP500-70EP should have no problem powering your system with an ASUS GeForce GTX 670 Direct CU II TOP 2 GB.

    BF3 would be the most GPU intensive of the games you've listed. When playing it at a resolution of 1920x1080 at its highest visual settings a GeForce GTX 660 Ti should give you at least 60 FPS. The ASUS GeForce GTX 670 Direct CU II TOP 2 GB would give you at least 74 FPS.

    I would recommend the ASUS GeForce GTX 670 Direct CU II TOP 2 GB since games will only get more GPU intensive.
  15. I'm using an i5-3450

    It should consume at least 12 Watts less power than the Core i7-3770.
