Help with power supply for amd 6970 hd

lads i've built my system, and as graphics car arived(6970) i discovered a problem it needs 6pin(75w) and 8 pin(150w)
i have two six pin so its no problem as for 8pin motherboard is after taking that, how do i asemble 8 pin? friend of mine tellin me 6pin=8pin but acording to some search on internet their not ((The AMD Radeon HD 6970 uses both an 8-pin and a 6-pin PCIe power connector located at the end of the video card on the top corner. AMD didn't tell us what the power supply requirements are, so we pinged XFX and they were happy to let us know. AMD recommends a 550 Watt or greater power supply with one 75W 6-pin PCIe connector and one 150W 8-pin PCIe connector on the Radeon HD 6970. ))
power supply is 850w

  1. what is the model of your Power Supply ? and for sure AMD tells the minimum requirement power for your GPU
    http://www.amd.com/us/products/desktop/graphics/amd-radeon-hd-6000/hd-6970/Pages/amd-radeon-hd-6970-overview.aspx#3
  2. yes i know it needs 75w and 150w
    how can i make 150w on a 8 pin from the other connections? i have one free 6 pin(on the same line as the one pluged in in a graphics card already
    power supply is win power plus
  3. If you have an 850 watt, I'm surprised you don't have an 8 pin PCI-E connector for your GPU.
  4. listen, if your PSU is a cheap one and unknown brand, it will fire out your whole system when you make a load at your PSU.
    and if a 850W PSU doesn't have at least 4×(6 pin) and 4x (6+2pin) it can't handle a Crossfire or a SLI system. or even single powerful GPU.
    so if you have a link for your PSU provide it. but i'm afraid i say you'll have to change your PSU
  5. What is the make/model of your PSU?

    You can use a 6-pin for the CPU power and use the 8-pin from the CPU to use on the GPU.

    What CPU do you have?

    Don't use the card without all the necessary power connectors
  6. cpu is overclocked i7 2600k
    power suplly came with the case
    i think its one of the cheap ones alrite, any links to the good power supply that would suit
  7. If your O.C.ing it then nvm don't use a 6pin for the CPU power.

    What is your budget for a new PSU?

    Are you sure your PSU isn't modular?
  8. if you aren't thinking about Crossfire / SLI in the future here is your best fit

    if you're seeking future upgrades, then the one Purple linked is a best fit as well

    i wont be doing anything to graphics card, cpu came over clocked but i have it disabled as i dont use computer for heavy gaming anyway
    i'd like to go with strong enough psu just in case i get another 6970 for christmas
  10. the one linked above by Purple Stank is a good one, and here's a 800W PSU

    yes that sounds good, i'll order this one, is there anyway i can conect my card to start my system?
  12. not until you get the new PSU... for your PC safety :)
    you just plug the 6 pin PCI Express and the 8 pin PCI Express directly from the PSU to the GPU. that's all
  13. thanks lads
  14. Welcome.

    Goodluck.
  15. oh also should i order new case aswell as my ones cover slightly touches the top of the procesor's heatsink
  16. What heatsink are you using?

    Yes get a new one.A bigger case is always better.

    aha you got a big monster here, so what's your budget for the case ?
  19. not much after i bought that psu, delivery is a killer, 180 euro all in, i think i'll have to take that side door off and introduce it to the hammer :D
  20. sounds like a good option LOL
  21. what's your current case ?
  22. its only barely touching the cover but its obviuosly aplying small bit of presure to the tips of the cooling rods and that cant be good for the motherboard, also do you know if front usb3 ports will work with usb2 keys or should i get card reader with separate usb2 slots?
  23. USB 3 is fully backward compatible with USB 2 devices, so if you plug in USB 2 device in a USB 3 it will work without any problem.
  24. case and psu (same as in that link)

    i chose that cause i wanted plain one, didnt want any fancy lights as the computer is in the bedroom
  25. one of the CM HAF series will be great for your rig. does the HD 6970 fit properly ?
  26. Yah that's a really cheapo case.Especially for such high quality components like your using.
    The HAF 912 is fairly cheap but still offers good expandability.The HAF series are really wide so they can accommodate a bunch of really tall coolers.

    http://www.newegg.com/Product/Product.aspx?Item=N82E16811119233&Tpk=HAF%20912

    The Antec 300 Illusion is also a good option.But if your using the Noctua I suggest going with the HAF to get as much clearance as possible.

    yes it fits, the only thing if i fit secondary hard disc inline with it will be very close to gpu so i'll keep that couple slots below, primary had disc is solid state and very small so no problem at all

    but you still need a decent case for the best fit and better cooling
  29. Yah I agree.If you have some extra money you might as well get a new case.It will benefit you in the long run.
  30. lads still havin problems, got my power supply today, connected up, screen turns on, windows starts, but it doesnt reconize my video card, card is working as the fan is turning and monitor is working (connected to gpu) i'm using windows 7 64bit, if you going in tom change resolution it says, standart graphics adaptor, did i connected something wrong
  31. does anyone know how exactly to connect power to that graphics card
  32. what PSU do you have ? you just connect the PCI Express 8pin and the PCI Express 6 pin
  33. http://www.newegg.com/Product/Prod [...] 6817171057
    the one you recomended
    cooler master 800w
  34. there isnt 8 pin, only 6+2 pin x3, but i dont think their 150w as 6pin is only 75w and the other extra 2 looks like ground
  35. 6+2 pin is the (8 pin) hook the 2 pins near their brothers (6pins) and connected it to the GPU, and take a single 6 pin and hook it up to the 6 pin (female) in the GPU
    those ones
  36. dont work that way, i tried i cant see that suplieing 150w as 6 pin only 75w, i tried to switch bios on the graphic's card, but no luck either, as on my old car i had to switch it to work
  37. don't make your own assumption, the 6 pin gives 75W and the 8 pin gives 150W i'm not electrician to tell you how it works. but they supply power as i said and the PCI Express expansion slot itself gives 75W
  38. Did you disable the onboard GPU?
  39. that card is doing my head in now, what do i do now?
  40. Even if it wasn't getting enough power it would just downclock.It would still be recignized by Windows.
  41. purple stank said:

    no, where do i do that? i dont think it was ever on anyway, i was using 4870 before that and i didnt had to disable anything
  42. Which mobo are you using again?
  43. the on board graphics card is disabled automatically once a discrete GPU is installed, and if it's still on you should hear the PC peeps and everything running normally.

    @ gedis what's your problem ? are you having problems getting signal from the GPU ? or you have a windows problem ?
  44. ''standart vga graphic's adapter'' it says in resulution vindow and if i go to settings its only 16mb
  45. that's because you didn't install the GPU driver :S
  46. Did you install the drivers for the card?
  47. the CD that came with the card, put it in and install driver from it, or give a jump to AMD website and download the latest drivers.

    i think its signal from gpu, vindows should have no problems as its only 2 weeks old and never been on internet yet, maybe it needs updates or something?
