Hd 5670/6670/gt630 on 300w psu

Hello,
I have an ATX 300w psu (atx0300p5wc) which has 19A on the +12v rail, 25A on 5v and 18A on 3.3v rail. will i be able to run any of these graphic cards on my computer as i cannot afford to purchase a new psu at the moment? hd5670, hd6670 or gt630

  1. That's just 228w on the 12v rail, and it's probably not a high quality psu. What is your cpu and motherboard? I have my doubts that it will work.

    oh thanks... my cpu is a hp compaq dx7400, core2duo processor with 2ghz and it has 2gb of ram.. motherboard is msi oab8..
    u think it might work?

    The gt630 should work...the core 2 duo takes up 65W, the card 65W, the ram probably 10W, the motherboard probably 40W. That is 180W used up with 120W left over for keyboard + mouse + any connected USB devices. As for the AMD cards, I don't know.
  4. Not the most power hungry cpu so it might work, but it is a risk. A cheap psu with years on it's back won't be able to handle much. You'd be cutting it close. Something like a 5570 should be safer. The 6570, 6670 and 630(really a rebranded 440) all pull about as much power as they can from the pci-e slot, the 5570 pulls a little less.
    I am by no means guaranteeing that the 5570 will work mind you. On an old dell optiplex gx620 that I had, the standard 300w power supply could not handle it. However, your cpu is more power efficient than it's was.

    Do you have a gpu installed in it now, or are you running off integrated graphics?
  5. I know a guy who said his 6670 was working on his 220 watt , 4gb ddr3 and athlon II x4 pc.

    Go with hd 6670.it will easily work.donot get gt630 really bad.go with hd 6670 it consumes 50w at peak.
  7. I did not have any of these cards but I had the Sapphire HD 4670 and GT 430 Before ( I think they are the older versions of 6670 and GT 630). The HD 4670 is actually faster but I had more problems with it
  8. By the way. It will work with your 300 watt psu. I had that set up for my little brother
  9. i got a 1gb hd6670 ddr5 and it works perfectly without a problem.. finished playing assasins creed2 on high graphics and crysis2 plays like butter.. gotta try newer games though. :)
