ATI HD 5670 on 350W PSU?

Hi! I'm looking to replace my broken NVidia 9800GT with the ATI HD 5670. Would my PSU be sufficient to run it?

Lite-On PS-6351-2
350W Dual 12V Rail
5V @ 18A
12VA @ 12A
12VB @ 18A
3.3V @ 17A
3.3V & 5V Combined Load Max of 160W
12VA & 12VB Combined Load Max of 300W


The official recommended PSU for the 5670 is 400W, would I be taking a risk if I ran it on a 350W? Would it make a difference if I bought Powercolor's Go! Green edition?

Thanks!

  1. The HD 5670 consumes less than the 9800GT so you have no problem.

    But as you said, that's a replacement not an upgrade, for an upgrade get the HD 5750, the 512 Mb version is only a bit more expensive than a 5670. And it will still consume less than the 9800GT.

  2. Thanks for the reply Mosox. My top priority right now is stability. The recommended power for the HD 5750 is 500W, which seems to be overkill for my 350 W PSU. I don't really wish to risk frying another video card.

    Considering my PSU, my safest option is the NVidia GT240 DDR5, which only requires 300W. The HD 5670 seems to be the superior card though. In view of this, do you recommend I stick with the HD 5670? How reliable do you think it's going to be with my PSU?

    Thanks again!

    It should do fine on your 350watt (strong 12 volt rail). When manufacturers recommend 400watt they are looking at generic supply's with less power on the 12 volt rail than yours.

    One last question before I make the purchase:

    Sapphire at $89 http://www.newegg.com/Product/Product.aspx?Item=N82E16814102871

    vs.

    Powercolor's Green version at $119 http://www.newegg.com/Product/Product.aspx?Item=N82E16814131348


    How significant is the difference between the "Green" and regular versions? Is it worth the extra 30 bucks?
  5. You could also upgrade that psu with another such as a cooler master. A 400 watt CM is reviewed here http://www.hardwaresecrets.com/article/975

    http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=3441837&CatId=1078
    30.00
    That would power the cards mentioned here

    edit : I like this 5670 http://www.newegg.com/Product/Product.aspx?Item=N82E16814161319&cm_re=HD_5670-_-14-161-319-_-Product

    I would not pay extra for the 'green' version. They just came out with a green 5750, for 180.00! Its more of pay extra for no fan, i'm green :)

    I would not spend the extra $30. The extra memory on the PC card can hardly be utilized by a GPU at that performance level and that huge heat-sink is for silent operation.
  7. Gotcha. Thanks for all the advice, you guys! Much appreciated! :)
  8. It should run fine unless your PSU is a POS and fluctuates when it's under half load. Those Lite-On PSUs are cheap, but they are usually pretty decent so I say just try it and chances are it will be fine. If you have any stability issues, then you may have to look at your PSU.
  9. IMHO, there's no such thing as overkill when it comes to PSU size. An oversize PSU is the cheapest insurance you'll ever buy for your syetem.
  10. I bought the sapphire one also, hope it arrives soon..
  11. actually get the card that supports eyefinity, its cheaper even with the free shipping.
