Best GFX Card for 400w PSU?

I've got a 3-year old Gateway GM5474 and the 8500GT died today.

I'm looking for the best graphics card this computer can handle without having to upgrade it's 400 watt power supply.

I'd also like to note that upon opening the case I only saw one 4-pin power connector opposed to the 6-pin ones required for most cards. Do these cards come with some kind of adapter or will I need to buy it separately?

Any insight is greatly appreciated, thanks in advance. :)

    A card like this does not need external power and is a big upgrade from 8500GT http://www.newegg.com/Product/Product.aspx?Item=N82E16814143186
    It will run on a 400watt PSU
  2. Thanks for the fast reply.

    That does indeed look like a big upgrade. Discounted price, free shipping, lifetime warranty. Great find. But I noticed that the PSU requirement is 350w, couldn't I get something stronger with a 400w requirement? I also saw that there are other 9800 GT's with 1gig memory, wouldn't that be better?

    I'm a little disappointed though, is this the best my computer can take? I'd like to add that I do quite a bit of gaming. I understand that I limit my options by not upgrading the PSU but that's because I plan to build something better and I'd like to save for that.

    Thanks again.
  3. The 9800GT is not powerful enough to noticeably gain from 1GB ram over 512Mb.
    If your PSU has 24amps or more on the +12 volt rail you can run a card like this http://www.newegg.com/Product/Product.aspx?Item=N82E16814134095 IT would require 2 x 4 pin molex from your PSU to be adapted into one 6 pin PCIe connector. Being a Gateway I am hesitant on recommending HD5750 card which is a great card but people have had issues with some older OEM systems with the HD5xxx cards.
  4. According to my PSU specs (http://support.gateway.com/s/POWER/6506042R/6506042Rsp2.shtml) it has only 16 Amps on the 12V rail? I guess that means I can't run the GTS 250.

    I'm leaning towards the 9800GT but any more feedback is greatly appreciated.
  5. You have a combined 30A on your +12V rails (there are two). You could run a HD5770 on that PSU if you wanted to.
  6. I only see one 4-pin connector coming from my PSU and these cards require two. Even if I meet the Amp requirement how can I properly power these cards?

    If I can, maybe I'll be able to get away with the 9800 GTX? It has a 450w requirement. Would this be worth the extra 60$ compared to the 9800 GT?

    Still need an answer before I can make a decision.
  10. I'd go with the 5770. If you look at the bundled picture you'll see it comes with an adapter that uses 2- 4 pin connectors to power the 6 pin PCIe connector.

  11. You can put a jumper lead from maybe a hdd power connection to get the other connection to the adapter that comes with the card (most likely that card is going to be fine connected with 1 4 pin molex to the adapter).
  12. No, it will need both. Although rolli's answer would solve the problem. The 5770 uses about 100w at full load, about 78w at normal 3D use. The PCIe socket supplies 75 watts, the additional 25w needed would probably be handled by the single 4 pin.
  13. And I'll only be able to connect one of the two 4-pin connectors in the adapter. Will this work fine?
  14. So then it wont need both? rolli's answer sounds a little complicated to me.

    If I wont run into any problems using a single 4 pin I'll give the 5770 a shot, I hope there's no bottleneck. Is there any particular reason you chose ASUS over the other manufacturers?
  15. Looks like a great price on that Asus, especially if you play the rebate game and win. Asus has a good reputation in general, and with that price, that's probably why he picked it.
  16. http://www.newegg.com/Product/Product.aspx?Item=N82E16814130435

    Unsure if you've found a card, but this is a decent one also for the price. It only requires 400 watts to run also. It also comes with a converter I believe that turns 2 molex into the 16x 6 pin(?). So you would be set.
