New build, power supply advice.

I was going to build a new PC based around the 2500k and a GTX 570 and 8gb ram. For now, I will only use one 570, however, down the road I may upgrade to another 570.

I was looking at power supplies, and was wondering if this is a good part? I need to keep the price down, because I am trying to not get too expensive with my build.

  1. For one 570 that PSU should do the job just fine. If you're going to SLI 570, then it may be cutting it close.
  2. I haven't seen many OCZ PSU's reviewed well . Example:

    Compare that with the FX Black 750

    If ya tryin to keep the budget down, compare the 560 Ti (900MHz) and the 570 and consider if its worth the extra cost.

    Guru3D uses the following games in their test suite, COD-MW, Bad Company 2, Dirt 2, Far Cry 2, Metro 2033, Dawn of Discovery, Crysis Warhead. Total fps (summing fps in each game @ 1920 x 1200) for the various options in parenthesis (single card / SL or CF) are tabulated below along with their cost in dollars per frame single card - CF or SLI:

    $ 205.00 560 Ti - 900 Mhz (495 fps /862 fps in SLI) $ 0.41 - $ 0.48
    $ 320.00 570 (524 fps / 873 fps in SLI) $ 0.61 - $ 0.73
  3. Okay, I plan to wait on the really good power supply until I SLI. So, how much power should I have for a 2500k, GTX 570, and 8gb ram, and 1 hdd.

    How much power would you recommend for that?
  4. The OCZ ModXstream 700W is not going to support a build with two GTX 570s. This is because it doesn't have enough PCIe connectors (four are required, the MXS700 only has two) and you would be using up all the 4pin peripheral connectors to use adapters.

    Either of these would be better:
    XFX Pro 650W Core Edition 80Plus Bronze $90 ($6 shipping)

    OCZ ZS Series 750W 80Plus Bronze $100 ($25 rebate)
    Strangely one of many OCZ power supply series which have been positively reviewed in the last year or so.
  5. When in doubt, do the simple calculations to objectively determine what power is required and what PSU will meet your current and future needs. No guessing required to get factual information.
  6. Good units.
    XFX 750W PRO750W - $69.99 USD /after mir

    XFX 750W PRO750W XXX Edition - $89.99 USD/after mir
  7. Okay here are my options.

    1. Gigabyte GTX 570 + CORSAIR Enthusiast Series TX650 V2 650W $378

    2. EVGA SuperClocked GTX570 + CORSAIR Professional Series HX650 650w $400

    3. EVGA SuperClocked GTX 570 + Thermaltake TR2 RX 750W $ 380

    4. MSI GTX 570 + CORSAIR Professional Series HX650 $370

    Or I can just get the GPU and the PSU separate, which will loose me some money on combo discounts.

    EDIT: Upon further review I have decided to get my GPU and my PSU separate, getting a good discount by buying my case and PSU together. I decided on the Cooler Master Storm Scout w/ a Cooler Master RS700 700w power supply.
  8. Better offer no matter how you slice it.
    Less money then any Newegg deal $360 after mirs
    You get a superior 80+Silver 750W modular psu + GTX 570/w free game
    Free shipping on the whole order.
    XFX 750W PRO750W XXX Edition - $89.99 USD/after mir [...] acture=XFX
    MSI GeForce GTX 570 Fermi - $269.99 USD /after mir

    $40 cheaper then your best quality combo which #2
    $10 cheaper then your 2nd best combo #4
    $18 cheaper then your #1 non-modular offer
    XFX PRO750W XXX Edition psu is a higher power and higher quality unit then any unit you've listed
    #3 combo features a terrible psu that's to be avoided at all cost/max power is under 600W = POS
    The case combo features another POS power supply .
