  • Power requirements for graphics cards

    As so many people aren't sure how much power a modern graphics card requires MINIMUM, I've decided to write a list of various models with the sort of PSU they require. Obviously it would be better to get something better than what is stated. It is only a rough guide, as it also depends what other hardware you have in your system. I hope it is of some use to people.

    The following are the minimum power requirements using a PSU with a single +12V rail. Also these requirements are for a system containing basic components (unless otherwise noted). The more add in cards and hard drives that a system has, the more amperage draw on the 12v rail.

    UPDATE:

    AMD's new Radeon HD 6850 and 6870 have been added to the list. These two new cards are basically the next generation up from the 5750 and 5770, and offer performance close to the existing 5850 and 5870.

    For a system under load the following power consumption figures are given:

    1X 6850 = 278W /12 = 23.2A2X 6850 = 393W /12 = 32.8A

    Page 3 of 8Power requirements for graphics cards

    3/5/2014http://forum-en.msi.com/faq/article/printer/power-requirements-for-graphics-cards

  • 1X 6870 = 295W /12 = 24.6A2X 6870 = 421W /12 = 35.1A

    That is based on a system with an X58 based motherboard, Core i7 965 @ 3750 MHz and 6144 MB (3x 2048 MB) Corsair DDR3 RAM @ 1500 MHz.

    http://www.guru3d.com/article/radeon-hd-6850-6870-crossfirex-review/4

    Based on that I've given the following recommendations:

    Radeon HD 6870 CrossfireX - 38A and a 650W PSU minimumRadeon HD 6870 - 28A and a 500W PSU minimumRadeon HD 6850 CrossfireX - 35A and a 600W PSU minimumRadeon HD 6850 - 25A and a 450W PSU minimum

    I'm trying to make the list more realistic for any future graphics cards. Updates will be given showing my research.

    UPDATE:

    The GeForce GTX 580 has been added to the list.

    For a system under load the following power consumption figures are given:

    1x 580 = 451W /12 = 37.6A

    That is based on a system with an X58 based motherboard, Core i7 920 @ 3.70GHz and 6144 MB (3x 2048 MB) G.Skill DDR3 RAM.

    It seems the GeForce GTX 580 uses slightly less power than the GeForce GTX 480, although there are reports on other sites it uses more power with the older VBIOS.

    http://www.techspot.com/review/337-asus-geforce-gtx-580/page11.html

    Based on that I've given the following recommendation:

    GeForce GTX 580 - 40A and a 600W PSU minimum

    UPDATE:

    The GeForce GTX 570 has been added to the list.

    Please note the following though as reviewers are changing their method of measuring power consumption:

    "As of lately, there has been a lot of discussion using FurMark as stress test to measure power load. Furmark is so malicious on the GPU that it does not represent an objective power draw compared to really hefty gaming. If we take a very-harsh-on-the-GPU gaming title, then measure power consumption and then compare the very same with Furmark, the power consumption can be 50 to 100W higher on a high-end graphics card solely because of FurMark.

    After long deliberation we decided to move away from Furmark and are now using a game like application which stresses the GPU 100% yet is much more representable of power consumption and heat levels coming from the GPU."

    Techspot have also started to measure the power consumption differently and have given very similar
