250W PSU and an HD 6670 GPU?

Hello!

As the name of the thread says, I am wanting to run a HD 6670 on my computer which has a 250W PSU.

I have used wattage calculators and have come up with anywhere from negative to positive results from them.

But here are the specs of the computer:
AMD Phenom II x4 960t
8gb of DDR3 ram (2 sticks of 4gbs)
The computer has one combo CD drive
2 fans
And the hard drive is a 1TB SATA

So what is your opinions? Will my system be able to handle the 6670? Or do I absolutely have to upgrade my PSU?
I want to avoid having to upgrade it if I can.

Thanks so much!

  1. no, a 250W PSU isn't enough for ANY gaming video card minimum recommended in most video cards is 400W under that you will certainly run into problem, if not in a short time period in some moths you will run into problem...

    i recommend you this PSU goo price/quality:
    http://www.newegg.com/Product/Product.aspx?Item=N82E16817139026

    you will certainly toast your video card running at 250W or it will be running at very unstable voltages what will cause bad performance and in some time it will also probably die.
  2. But the card itself only uses 65w so that really doesn't make sense to me at all.
  3. No dear god almighty no The card uses 65. You now only have 185 for your hard drive, cd drive, fans, and processor... That is simply not enough.
  4. You're on the limit of your psu without any card, so you really can't have any card with your cpu and a 250w psu. You never want to go more than ~75% of the psu or else burn it out quickly. Think of it as if you had to run almost as fast as you can for a couple of hours or how ever long you play games. I would suggest you get the cx430 like ricardois suggested or else go higher to reuse it for a new computer.
    x4 960t=95w
    6670=66w
    hdd=~10w
    cd=~30w
    other components=~50w
    =~250w
    Of course this is simplified without confusing you with actual psu power/amp limits on 12v, 3.3v, 5v rails and such.
  5. This is the calculator Im using.
    http://www.msi.com/service/power-supply-calculator/

    And it tells me with all of the components that at absolute maximum they will all use, including the graphics card, 231W.

    Now another question I have is, is 250W actually the max output? Cause I read somewhere the maximum of a 250W is a little over 300w. Is this true?

    only very good quality PSUs can output higher than rated spec.

    a low 250w PSU is almost certainly advertising its peak output, not sustained.

    really, the other guys are right. you've asked the question, and ignoring the answer would just be stupidity. you simply cannot run that system of such a weak PSU.
  7. I wasn't ignoring the answer. I was only trying to come to a different conclusion. But I see now that it is important that I get a new PSU so I am looking at them now and am probably going to go with a 500W Cooler Master.
    http://www.amazon.com/Cooler-Master-eXtreme-Series-RS500-PCARD3-US/dp/B001G0WPLK/ref=sr_1_1?ie=UTF8&qid=1334145074&sr=8-1

    Would this one be okay?
  8. coolermaster aren't very good.

    this corsair is 40 bucks after a mail in rebate: http://www.newegg.com/Product/Product.aspx?Item=N82E16817139027

    would be miles better.
  9. go with the corsair better price performance, you need ACTIVE PFC psus, those that don't have the voltage switch 110-220, they are automatic, they are much more safe, and handle much better attenuations on your eletric wiring.
  10. how much amps are in the +12v rail?

    the system will have no problem on 250w if the psu can actually output 250 continuous.
  11. also coolermaster has bad psus.
  12. Yeah...try and at least get something like 400 + and stay away from cooler master; only a few of their higher end PSUs are any good. Personally I have an antec PSU, but Corsair is a really good brand, they cut no corners.
  13. MY Hp Pro 6005 SFF is running a sapphire HD6670 with a 240 watt psu with no issues!
  14. I went with the Cooler Master. I can't afford anything else at this point. Im not looking for a perfect gaming system. Just one that will run the 6670. Im fine with the cooler master. Especially considering all of the good reviews on many websites.
  15. It will run it with no issues!

    Which is about what I gave you and explained how it is unsafe.
  17. I am wanting to buy the HD 6670 in my Inspiron 580s with a 250w PSU. Specs:
    i3 530 running at stock clocks 2.93 GHz
    1 WD Caviar Blue 320GB
    1 Lite-On DVD-RW, DVD-ROM Combo Drive
    2 Cooling fans
    Intel H57 Motherboard
    Windows 7 Ultimate 32-bit
    4GB 1333 MHz RAM (2 sticks)
    PSU Specs:
    Dell Bestec 250w PSU
    100-120V-6A 200-240V-3A 50/60Hz
    +12V-17A
    +5V-18A
    +3.3V-11A
    +5 and +3.3V-120w Max
    Total Power Output-250w
    A guy who bought the card from Amazon said he could run it in his machine with no problem. Can I too run the HD 6670 or the GT 430 ? I personally prefer Nvidia.
  18. I've been running one in my hp pro 6005 for over a year now.
  19. You could probably run it for sure...but for stability issues, you may have a problem. Personally, I only have never used a 250w PSU on any build, but I would just be concerned about the actual power draw versus rated. If your PSU only gives out, say, 200w (that's with an 80% efficiency rating which it most likely does not come with) and your build needs 210w to run with the card, well, your computer will have random crashes and/or shutdowns. Just my two bits
  20. Yeah it should work. Alienware x51 runs a 105w gpu on a 240w power supply.

    I sure havent heard any problems from anybody running a 6670 on a 250w psu.
  21. Hi, so I got my HD 6670 and it runs like a dream!!!!!!!!! Thanks you all! :D

    is that true? i want to upgrade my 6005 sff as well ..

    6670 or 7750 will work in a 250W PSu
  24. i know but the hp brochure says that the pci e x16 slot can only provide 25W in sff systems

    Can you show me a photo of your system with the card in it?

    Just look at your power supply and check how many amps are on the 12V rail.
