Is this enough power?

Hey guys... heres a setup I'm looking at buying.. Could you verify its enough power on the PSU please?

I will want to add another 670 in future (not soon anyways), Possibly window case and lighting.. and WAYY off down the line, ill eventually upgrade to a i7

Side questions:
Would it be worth getting a fan controller for this system?
Im not fussed about overclocking, but i have the setup to do so when i need to..
How can i reduce the price of the system but still keep a spec there abouts!?(cheaper dvd drives? Cheaper SSD?

Thanks for your time :)

  1. howdy
    650watts will be enough for a single card, if you want to sli in future you should get 750-850 watts
    i dont invest in fan controllers, you can connect the fan to your mobo and control your speeds from there
    you can save money by going to 8 gigs of ram, for gaming you wont see performance increase with going over 8
    dont forget to purchase windows oem too
  2. 650W is actually quite an odd amount to use. 500-550W is pretty standard fare for most single GPU setups, depending on the chip of course. That figure leaps up to 700+ when you start using 2 mid-high end cards. For SLI GTX670, they reckon 750W is about right, and that should give you plenty of scope for overclocking too.
    At your price point I'd look at the XFX Core 750 or Pro XXX 750 if you want a modular version.

    Ways to reduce price-
    Cheaper motherboard, ASRock Z77 Extreme 4 is around £100
    Drop to a 2Gb GTX670. It won't make any difference to performance unless you plan on very high resolutions or mods.
    Drop to 8Gb of ram, similar reasons.

    Fan controllers are fairly aesthetic. I own one of these-
    Looks great, and kinda cool to be able to tweak settings at ease, but in terms of a cost/performance investment? pointless really.
    The main reason to own one is perhaps because you have a need for more fans than you have motherboard headers.

    I'm under the impression that the board allows me to automatically connect to wifi, which is a very useful feature in my home setup, or does wifi go only allow control of the system from a remote location.

    I'm using the graphics card for 3d modeling and rendering also, so alot of power would be usefull.. Does this not effect?

    I guess ill look at a 750 then!
  4. Yeah some boards have built in Wifi, my motherboard does. Question is whether or not the £45 price difference is worth it, you can buy a wifi card for half that. There's actually not a huge amount of Z77 boards that do have wifi built in.

    4gb of vram is usually more than is necessary, but it'll really depend on the task. For gaming there's not going to be any difference really, it's all about the GPU. 3D modelling won't hurt it either (I do a fair bit myself). Rendering I'm not sure, it'll be program based anyway. It might be worth checking what will actually benefit the programs you intend to use.
  5. To answer your question, yes your psu is sufficient for a single GTX670, but not for two of them.
    Here is a handy chart of psu requirements:

    Other things light drives, I7 and lighting do not significantly add to your power requirements

    For rendering, you might want to buy the 3770K up front, It makes no sense to me to replace a 3570K.
    For gaming, the 3570K is the equal of the 3770K, so decide how important each workload is to you.

    On planning for sli, I am not much in favor of that.
    Here is my canned rant on that:
    -----------------------------Start of rant----------------------------------------------------
    Dual graphics cards vs. a good single card.

    a) How good do you really need to be?
    A single GTX650/ti or 7770 can give you good performance at 1920 x 1200 in most games.

    A single GTX660 or 7850 will give you excellent performance at 1920 x 1200 in most games.
    Even 2560 x 1600 will be good with lowered detail.
    A single gtx690 or Titan is about as good as it gets.

    Only if you are looking at triple monitor gaming, then sli/cf will be needed.
    Even that is now changing with triple monitor support on top end cards.

    b) The costs for a single card are lower.
    You require a less expensive motherboard; no need for sli/cf or multiple pci-e slots.
    Even a ITX motherboard will do.

    Your psu costs are less.
    A GTX660 needs a 430w psu, even a GTX680 only needs a 550w psu.
    When you add another card to the mix, plan on adding 150-200w to your psu requirements.

    Even the strongest GTX690 only needs 620w.

    Case cooling becomes more of an issue with dual cards.
    That means a more expensive case with more and stronger fans.
    You will also look at more noise.

    c) Dual cards do not always render their half of the display in sync, causing microstuttering. It is an annoying effect.
    The benefit of higher benchmark fps can be offset, particularly with lower tier cards.

    d) dual card support is dependent on the driver. Not all games can benefit from dual cards.

    e) cf/sli up front reduces your option to get another card for an upgrade. Not that I suggest you plan for that.
    It will often be the case that replacing your current card with a newer gen card will offer a better upgrade path.
    The GTX780 and amd 8000 series are not that far off.
