More about recommend 850w modular
  1. Go with the Seasonic X one.
  2. What's your budget?

    Well, all of the PSU's recommended fall within the 150-250 dollar range so budget isn't AS important as it would be in other components

    Isn't Corsairs AX850 just a renewed SeaSonic X? Because SeaSonic is the company who manufactures it.
  5. More Options:
    Antec HCP 850
    Enermax - Revolution 85+
    OCZ ZX 850W

    IDk, if Seasonic manufactures it, but the AX850 is based on Seasonic's high-efficiency 80 Plus Gold certified X-series.
  6. Go to realhardtechx.com and check the PSU review database. The Corsair AX850 has the most reviews all with high praise.
  7. I'll recommend this PSU since you got Z77 with 2 670s...

  8. I would suggest you to go with Antec CP850 as it's Modular 850W Continuous Power PSU and It may support GTX 570 SLI.. So I recommend you to go with "Antec CP850". :)
  9. yes Seasonic manufactures XFX, and Corsair PSU

    reason why you want to go Seasonic X series

    1)it is very quiet
    2)has 3 fan options(reason why it is quiet)
    3)hybrid mode
    4)GOLD rating

    AX series i have to say isnt as good as Seasonic X series

    i would rather go with Corsair HX series over AX

    i would also change the 850W into a 1000W there is not much of a price difference and you can pretty much take that 1000W into any of you new builds

    not to mention 1000W has a hybrid switch so you can switch it when ever you want

  10. Any of the Silverstone Stryder PSU's will work since most of them are 100% modular. I had a 850w for three years and it worked like a champ.

    I have upgraded to a semi-modular Thermaltake Touphpower Grand 850w and it runs like a champ but has a four more years on the warranty over the standard three year that Silverstone offers.

    Both are under $200
  11. So majority of people here are saying the SeaSonic X-Series PSU's are the best best... Whats the difference from the Corsair AX850? Like, is there any MAJOR difference?And isn't the X-Series outdated? I just want to be sure that the X-Series is a good psu to get.
  12. X-series is one of the best because it is a little old doesnt mean it can't do its job

    AX is not a hybrid fan and Seasonic X is

    it offers "Sanyo Denki San Ace Silent Fan"

    which means at idle it will switch to a fanless mode to save energy and stays quiet
    and at load it switches to the fan and i have to say it is really quiet and cools very good
  13. I'd actually suggest the Huntkey X7 900w, I have one of them running three HD6950s and it's quiet and seems to run fairly cool too. And it's not expensive - nice and reliable too.
  14. Seasonic X is better than any huntkey psu.
  15. The only reason i'm remotely considering the AX850 is the sexy ass sleek black cables it comes with. But... I guess its Quality>Aesthetics isn't it. lmaoo
  16. You can always sleeve your psu cables later on.
  17. Get a 650Watts PSU.. It can power a GTx 690... This video of 690 SLI is being powered by a 900Watts PSU, each 690 draw about 320watts so if you subtract 320 from 900, it's 580watts... 650Watts is all you need because 2 GTx 670 is the same wattage as a single 690 with pretty much huge performance difference...

  18. I am quite skeptical about the HX850 because it is made by Channel Well Tech while the AX850 is made by SeaSonic. According to some articles, the AX850 is SeaSonic's X series, just remastered into a second version of it. Plus, the Ax850 will also not spin unless it is under load. I have heard no reviews let alone unboxings of the SeaSonic X-Series X-1050w PSU, could anyone list a link to a review of it?
  19. Excuse double post, but my choices as of now are....

    SeaSonic X-Series X-1050(since it costs the same as the 850w)

    Corsair AX850

    I like how the X-series has an extra 200w to it. But I hate the gold on itt... Also, I love the coloring on the AX850. Is there a performance loss in terms of both PSUs?/
  20. no there is not they are practically the same

    only difference is the type of cooling it uses and Seasonic is better in terms of cooling and silence

    go for AX850 if you like it

    my preference would be the 1050W because you would rarely see it inside the build of the bottom corner
  21. I just got an AX850 and I have to say I'm overjoyed with it. I'm not taxing it at all (single GTX680 and an i5 3750K) but it's quiet, cool and I have absolutely zero complaints.

    I'd go with the AX850, and if you have a Fry's nearby, they're ~$20 less than at newegg right now.
  22. Just for reassurance - an 850w PSU will be enough to power all my components correct? I believe I listed them at the top.
  23. it would be more than enough, you can actually get by with a 750W

    if you plan on getting a 3rd 670 then you should have about 800W

    (even though people say you need +250W Each card added to the 500W recommended)

    the reason this is, is because 670 do not take a lot of power due to the smaller chip it uses.
    heck you can probably get by with a 650W with a 2x670 SLI
  24. I would get the Corsair HX850
    Pretty efficient and it has a long 7 year warranty! Also its modular so less cable clutter. Corsair PSU are high quality

    Yes, for the components you're using an 850W is more than adequate.
  26. Alright, so i'll get an 850W PSU. I just don't know what... as you can see from my other threads, the AX850 will have compatibility issuess with a motherboard that has an 8 and a 4 pin input...I won't be able to run sli then. So what other PSU's are recommended? :pfff: :pfff: :pfff: :pfff: :pfff: :pfff:
  27. get Corsair HX850

    it is very good, almost the same as AX but silver rated

    or

    Seasonic -x series 850W-1050W

    850W uses the same thing as 1050 and has free shipping, not to mention it is gold rated and looks better than the 1050

    1050 is same price as 850 but has shipping included and a hybrid switch, it is kinda ugly to look at ,but you won't be looking at it much

    another PSU that has been really popular no is NZXT HALE82

    NZXT is not well known for their PSU but this one was where they shine, it is great, cheap, and modular. pretty much everything you need too
  28. I have the Corsair HX850 running 8 hours/day for the past 2 1/2 years! No hiccups.

    My motherboard requires two 8-pin inputs, so I got an extra 8-pin power cable (different from 8-pin PCI cable)

    Ohh, I was actually looking at this one http://www.newegg.com/Product/Product.aspx?Item=17-151-111&SortField=0&SummaryType=0&Pagesize=10&PurchaseMark=&SelectedRating=1&VideoOnlyMark=False&VendorMark=&IsFeedbackTab=true&Keywords=%28keywords%29

    10 more watts,platinum, I think it supports 3-way SLI AND has the 2 inputs. I'd probably just have to sleeve the cables :l
  30. if it is a 3-way 670 sli i am pretty sure i will be enough

    another option is this one

    http://www.newegg.com/Product/Product.aspx?Item=N82E16817116012
    NZXT HALE90 850W gold

    looks pretty good inside white cases

    or

    http://www.newegg.com/Product/Product.aspx?Item=N82E16817116016
    NZXT HALE82 850W Bronze
  31. I like them but I have a black and red combo going on. So my options are:

    Corsair AX850 - Small PSU,Black with a HINT of gold, very nice cables. Only reason I am doubtful of it is because I want to purchase the Maximus V Formula motherboard. It has an additional 4 pin power input to provide extra power to the board. Its not mandatory though.

    SeaSonic Platinum Series 860w PSU - 10 more watts, SeaSonic branded, reliable. I don't really like the grey on it, and the cables are horrid. I don't feel like having to sleeve them.

    Which one would you go with?
  32. AX850 is a modular so if there is a pin that is bad/need you can just buy that cable and sleeve it yourself
  33. They're both good units.
    Go for the AX850, you seem to like it more.
    IMO, you won't really need that extra power for 3570k @4.5ghz.
    :)
  34. Haha yeah you got that right, I do like it quite a bit. I am just skeptical about the power input :x

    Don't worry, you're not running a power hungry CPU. :D
