Power Supply

Ok so I'm building my system,

AMD Phenom II X4 965 Black Edition Deneb 3.4GHz Socket AM3 125W

2 5870's cross fire

8gb mushkin blackline

MSI f90 FX gd70 Mobo

standard 300 cg seagate barracuda HD

Standard dcd rw recordable drive


I need to know if this power supply is enough to get full use of the system, consider there is no or minimal (like 5-10 %) overclocking on the processor and the ram running at 1600 if i'll be able to at 1.9 which people claim i can

Also in the future I was thinking of an attempt to use my bfg 8800gtx as a physics card, i messed up in my calculations (2 pci express connector X 3 cards = six needed) and this power supply only has 4, however I could use something like 2 of these http://www.newegg.com/Product/Product.aspx?Item=N82E16812887001

I already made the order overlooking the damned pci connectors, and from what i've read It should be ok. However can someone who really understands power supplies tell me what margin i'm at, if it's not enough, if it's just barely enough, or if I'm in the green with this setup

Thanks a billions in advance

  1. Best answer
    2 x 5870 and an 8800GTX, you need more power.
    This Corsair 850 is less money (AR) and better quality than the Xigmatek

    This 950w Corsair has all the pcie connectors you would need and is only $20 more than the Xig, and again , better quality

    If modular is what you want, this Coolermaster would work
    http://www.newegg.com/Product/Product.aspx?Item=N82E16817171048

    or, this Corsair

  2. I don't know who makes this ps. The 18 amp rails may not be enough under full load. I would post this question in one of the overclocker's forums. I recommend corsair as it has a high single 12v rail and doesn't overate their power supplies.
  3. Corsair it is!, I have to get in touch with customer support. I had a feeling that was the case it just that i already clicked order. The corsair should let me overclock a bit as well you guys think? My billion times thanks turns into infinity :D

    The Xigmatek is built on the same CWT platform as the Corsair TX , just lesser quality.
