    My friend and I have been arguing about power supply units for new computers. The problem that we both agree on is that PSU don't really have any sort of reliable rating system. You could have eight PSU rated at 600W, that is just the peak. One of them could run consistantly at 120W for all you know.

    The deal that came up is linked: www.zipzoomfly.com/jsp/ProductDetail.jsp?ProductCode=10009333.
    It's for a PSU that is 600W. I want to use it to power my system below, what does the OT think?

    System Currently Being Built:
    Antec P182 Mid-ATX
    Intel X58 Mobo
    Intel Core i7 920 w/ Thermalright IFX-14
    EVGA GeForce 285GTX
    3 x 2GB Balistix 1600 RAM
    10,000 150GB WD Raptor HD
    7200 1.5TB WD Black 32MB HD
    Samsung Optical BluRay/DVD/CD Burner

    :p

    That one should work fine.

    Yeah, that is how I feel about it. But I don't know the brand, this would be the first non-Antec I've ever gotten.

    I was planning on a Modular, and a 120mm fan so this meets those needs; however, it's not at least 750W (which is what I thought I should get).

    not really a fan of OCZ PSUs, but great price ($39.99 AR) for a 600W
    note that OCZ's rebate system sucks, submit as soon as you get it

    Yeah but truth be told: I don't care if the rebate comes or not, it's still a great price.

    Why don't you like there manufacturing? Have you owned one in the past? What happened?

    i had worst experiences with Antec.
    OCZ is fine, i just prefer PC Power & Cooling or the Corsair units.

    note:
    OCZ is OEM,... their PSUs are made be FSP Group
    PC Power & Cooling, Corsair, and Antec True Power PSUs are made by Seasonic
    OCZ bought/owns PC Power & Cooling

    Right on.

    How about SLI 285GTX? Could it perform?

    that OCZ has a 6-Pin and a 6+2-pin PCI-E power connectors

    GTX285 in SLI will require 4x6-pin PCI-E power connectors
    yes, you can use an adapter,... but I try to avoid those whenever possible.

    also,..
    Core i7 = 130W (11A)
    GTX285 = 183W (15.25A)

    SLI setup:
    11 + 15.25 + 15.25 = 41.5A or
    130W + 183W + 183W = 496W

    that OCZ has 504W (or 42A) on the +12V rail

    imo,... it might work but that's borderline. I would at least get a PSU with 50A on the +12V rail,... this will be the 620W-750W units

    I've heard rumors on two subjects: Rails, and Modular PSUs.

    I heard rails don't matter, just the Amp though a single 12v rail.

    I also heard that Modular PSUs are not as energy friendly since they create resistance at the point of where they connect to the PSU. I wanted a Modular for case temp management through better airflow.

    most of these units are actually single rail, then split virtually for multiple rails
    the 'true' multi-rail PSUs are rare or expensive as hell

    definitely go modular if you want cable management

    it really won't make any diff as long as the PSU is of high quality

    I've currently got power supplies from both corsair and ocz, both have been great.

    Yeah when picking out a power supply its more about what rail has what wattage. You could end up with a lot on the 5+ rail and not enough on the 12+ rail.

    "[FONT=Verdana,Arial,Helvetica]With the highest rated output of any SilverStone power supplies, the Zeus series represents the pinnacle of PS2 (ATX) design. The ST65ZF can deliver exceptionally stable, continuous 650W (710W peak) output that is normally reserved for industrial server power supplies. Possessing quad +12V rails, advanced connector options, and an intelligent thermal/load controlled fan, the Zeus ST65ZF is the ultimate choice for top of the line systems."

    all that matters is if the +12V can provide enough juice

    650W (710W peak) are the total for all the rails (+3.3V, +5V, +12V, etc)
    it says 504W(42A) / peak 540W(45A) on +12V
    that pretty much cover the cpu and GTX285 SLI alone
    but if he adds more components that uses the +12V rail,... e.g. drives (3A each),.. his system might starve
    better safe than sorry

    My main rig is a 700w OCX game x treme. It's running a core i7 920, 6gb of ram, a 150gb raptor, a 36gb raptor and a 1tb wd black drive and a radeon 4870x2 video card.
    My server has a 650w(or 620w, I don't recall) corsair tx series. I didn't want to spend the extra on the hx series, which adds modular cables, which was a big mistake on my part. It's in a box that's got a q9450, 4gb ram, 3 1tb seagate drives and a radeon 2400hd.

    *sigh*

    reliability aside, the only thing you should look at is the +12V rail
    +3.3V and +5V are pretty much negligible since they aren't as power hungry as +12V components

    components that uses the +12V = cpu, vid card, expansion cards, hdds, fans, etc.
    components that uses the +3.3V = RAM, ICs, etc
    components that uses the +5V = usb devices, fans, hdds, etc.

    now look at the specs of the OCZ 700W,.... checkout the +12V rail (in this case +12V1 and +12V2)
    [​IMG]

    the combined wattage for the two +12V rails has 552W. divide that by 12V,... you get 46A
    (you don't add 25A + 25A = 50A,.. it doesn't work that way)

    now look at the corsair 650W i posted
    [​IMG]

    it has 624W on +12V,... divide that by 12V,... you get 52A


    the Corsair is still a better unit.

    Frickin' nice response. I've never gone through the efforts of learning a ton about power supplies - I appreciate you sharing.
