    To what psu are you refering to? If you post a link or give a make and model, we may be able to help. It's just that at the moment, my crystal ball is on the fritz.
  2. More info.
  3. Yes it will work great.

    Just about any PSU would be "compatible" unless of extraordinarily poor quality or over-rated/under-sized.

    A high-end single-CPU single-GPU setup rarely uses more than 350W so any quality PSU over 450W would be sufficient unless planning to either go SLI or having lots of extra gadgets/drives/???.
  5. I will have a 500 GB HDD, a 60GB SSD, a Radeon Gigabyte 7870, 8GB 1600 RAM, and the cpu listed above.
    Is this enough watts to power the parts without being unstable???

    Stability is mostly a matter of quality, not quantity.

    Your system should not need more than 350W and will run fine on a quality 450W.

    If you use a crappy 850W PSU, you may have problems even though the PSU has a much higher decorative rating.
  7. But I have read guides and they always say not to skimp out on the PSU. would buying A lower wattage PSU be considered skimping out???

    wattage isnt "skimping" out. skimping out is when yoiu by a bad quality unit. there is 2 major thing to check for, and thats all the saftey features(overvolt protection, undervolt protection etc) as well as using 80+ as a decent indicator to shed off most of the bad ones. a barebone build can get away with 430-450w fine. an average single card build will use ~550w, a low power consumption sli/crossfire sits around 600-650w, high end sli/crossfire sits around 700-750w any more are for specific builds like tri-fire tri sli/physx addition etc
  9. there's skimping and then there's wasting money. it's a matter of finding the right balance.

    skimping is, say when you buy a $15 unknown brand 450W PSU of questionable quality when a good quality 450W PSU from a good brand usually costs $40-50 minimum. wasting is when you buy a quality PSU with a larger wattage than what your build would need at the very most, and then raise the electricity bills when you use it under it's rated load to achieve 80+ efficiency, say when you're simply surfing the web.

    there's more to a PSU than the number of watts printed on it; build quality, 80+ certification, and actual power on the 12V rail(s) are very important. as others has stated 450W will be enough. the 7870 and IB CPU are quite efficient. a good 450W PSU with a good amount of efficiency and power on the 12v rail will output more than 450W.
  10. Not really.By this they mean you shouldnt get a poor quality PSU not a low wattage one.
    The things InvalidError said are all true but since your PC has very gih overclocking potential a 450W PSU really isnt recommended.Im not saying it won't work because it will but if you want to add a new card or you want to reuse the power supply for your next build you should buy the best one you can.

    The power supply you linked isn't a very good choice because it uses a multi rail design with low amperage on each rail.
    Let me explain that in a better way.
    This power supply has four 12V rails.This means that one of the rails powers your CPU, two of the rails power two graphics cards and the last one powers everything else.Every rail delivers a maximum of 216W of power (18A x 12V = 216W) so if a rail uses more than 216W of power the power supply will shut down.

    If on the other hand you look at a single rail power supply like this one
    http://www.newegg.com/Product/Product.aspx?Item=N82E16817182084
    It has only one 12V rail.
    This means that its 12V rail is VERY powerfull.That means that even if one of your components uses 600W power it won't shut down.
    By the way if you want high efficiency at a decent price the Rosewill Fortress is the way to go!

    if your buying the fortress, at least give him the 20% off promo code RWCP2008(though i dont think it applies to the 750w model, but it does apply to the 450,550,650w fortress and 450,550,750w capstone modular)

    Not at that price point. Here's a pretty good deal:

    OCZ ModXStream Pro 600W - $44.99

  13. Thanks for all the help :):):):):)

  15. TBH I would not buy that PSU.

    Why Not????
  17. only because there are slightly better quality units for a similar price if you dont do rebates, example:

    PCP&C 90$ -15% 76.50 then a 20$ rebate
    Antec Earthwatts 650w (assumes you have a extra power cord 80 -15% = 68$ then a 10$ rebate
    Antec HCG 620w 90 -15% =76.50 then a 20$ rebate on that.


    are viable choices if quality to cost ratio is in mind. different brand psus always go on sale, take advantage of them to get better quality units for less.
  18. They're all a lot more expensive than the OCZ, which is more than fine.
  19. a 6.50$ difference in price(and 5$ in rebate if you do rebate) I wouldn't say is a lot to pay.. If you are looking at base prices, you must not understand what sales are and why they exist.
  20. 56.50/58/56.50 vs. 45 means a 26-29% price hike.
