More about what kind power supply need
  1. Your link does not work so please just name the parts you wish to purchase.
  2. 750W is probably overkill for "mild gaming". What kind of graphics card have you picked?
  3. When choosing a psu, you can't just rely on the rated wattage. A psu is one of those items that you can't skimp on. It touches every part in the system. If it blows, it can take something with it. The better manufacturers are corsair, pc power & cooling, antec, OCZ, and seasonic. I suspect a 'mild' gaming rig will require ~500w from any of the above manufacturers.
  4. ok so here is what im looking to get.

    intel quad core q8200 processor
    nvidia xfx mg 63mi motherboard
    nvidia 4gb ddr2 memory
    cosair 750w PSU
    nvidia evga geforce 9800 gtx+ graphics
    along with a case ultra etorque
    and some fans
    zerotherm chipset cooler
    ultra performance vga cooler

    tell me what you think
  5. yes it's overkill but drop the cpu, mobo and gfx card for a P2 940, 780G motherboard and 4770 gfx card.
  6. Well, if you are only going to use one video card and don't plan on using mutiple video cards, then a 750 watt power supply is more than sufficient for your needs. The very high quality psu's such as the Corsair TX750 you are looking at is designed for high end systems with two video cards in SLI or CrossFire mode.

    If you are positive that you will only be using one video card, then a high quallty 500 watt power supply such as the Antec Earthwatts EA-500 will meet your needs. It can power any single video card made.

    Here's a link to a technical review of the Antec EA-500:

  7. im going to be playing games like cod 4, waw 5(when it comes out) maybe a little crysis some CS. i want to try and stay away from AMD and am more into intel.

    is their something the matter with intel q8200? evga9800gtx+ and the xfx mg63mi mobo?
  9. yeah

    1) the Q8200 only has 4mb of cache and a 2.33ghz clock speed while the P2 940 has 6mb of cache which the architecture handles far better and has a 3.0ghz clock speed.

    2) 4770's when oc'd are better than the 9800GTX+ and use about 30w less, also cost less aswell. they get to about 850mhz if you use the rivatuner hack and even further if you have the ASUS TOP edition and up the voltage although they can get very hot.

    3) you need a amd socket motherboard for an amd cpu and nvidia chipsets are rubbish.
  10. Helloworld-98 - I knew Nvidia was having some problems but didn't realise it extended to their chipsets for desktop pc's. Do you have any references for the info?

    I would go with a 790GX mobo for the SB750.

    +1 for the rest
  12. Thanks for the advice. but for cost reasons i think im gonna stick with my current build. if i have problems with it i can always exchange it or sell it back.
  13. If you want to stick in that price range with an intel cpu, then go with the e8400. It's got a much faster clock speed. The 2 extra slow cores aren't going to do you any favors.

    The recommended parts are lower cost than your original selections.
