9800GTX+ questions

Thanks for looking at my questions.

I am about to pick up a 9800GTX+ 512 (55nm) and since my computer is kinda lower middle i am wondering if it can accomodate its power requirement. My current spec:

e5200 OCed to 3.7Ghz @ 1.42, p45-UD3LR, CPU coller is a non brand HDR with 120mm led fan, 4gb DDR2 ram, 250GB Sata HD, ATI 4650, DVD-ROM, 22"WLCD from HP, Logitech S510 mouse and keyboard bundle.

1. My PSU rated at 400w (360W continuous) with +12V rail rated at 18A.
I tested with PSU calculator and it "seems" its sufficient but i am not sure.

2. How much is the improvement am i looking at should i successfully installed this card? I am hoping day and night since i think my card is very crappy now.

3. the card says it needs 2X6 pins connector which my PSU doesnt have any at all.
Now, i have read that there is molex converter to 6pin (2 molex to 1 6pin each) means i need 4 molex. THe problem is i only have 3 spare molex left. Will it be safe and sufficient if i plug 2 and 1 molex to 2 of 6pins or 1 molex to each of 6 pins ?

I havent installed a powered Gcard before so excuse all my questions. I just dont want to spend more money on PSU if possible.

  1. your PSU is really underpowered. 18a on a 360w PSU is not much and no PCI-E is often the sign of a cheap PSU.

    I would suggest looking at the ATI 5750. it offers similar performance to the 9800GTX+ but is far better in power efficiency and only needs one adapter.

    the ATI 5670 is another choice, a step below the ATI 5750 but needs no power cable attachments.
  2. Thanks.

    But i am considering this card since i am getting 2nd hand card from a friend of mine seling it for 50bucks. :D
  3. Yes you might consider the HD 5670.... it is about 9800GT performance but doesn't require a power cable and that much power.
  4. so there is no way i can use this card without upgrading my PSU ?

  6. ok Time to upgrade PSU then.

  7. cheap PSU are just that, cheap

    ive never heard of the manufacturer you linked but in theory it should be fine

    Don't try to save money on the damn PSU! Those cheap PSU's use cheap parts that cause stability problems on machines better than office PC's. Get a quality one, from Antec, Corsair, OCZ, CM etc.
  9. PSUs are the most important part of a PC; getting a cheap one will trouble you in the future.For your needs a 400-450W PSU is the minimum.You can get a good deal with this one:

  10. ....hes not in the states, did you see his link?
  11. Cheers m8,

    Yeah i am not in states, in here those brand are overly marked up.

    The PSU i sent "seems" well enough with 2X +12V rated at 20A. But i am not very sure..

    now, leaning out of the discussion abit, anybody has a good experience OCing 9800GTX+ ?
  12. Dont even think about running a Graphics card in your system without changing your PSU.
    And dont fall for cheap ones either.

    BTW are u based in Japan?The link indicates so.

    It should not be so hard to get good PSUs over there.Get a good PSU that will suffice for the future like Antecs or Corsair.
