Instead of this one

The corshair one has single rail while the antec has 4 rails,
Which on is better and will be more future proof ?
I cant have things blowing up and stuff.
Does the corshair have over current protection ?

  1. if u ask me i better choose the

  2. The Antec TPQ only fits in certain cases also so be aware of that. The corsair would be a great unit and so would the Antec. Single or Multiple rails doesn't really make all that much a difference as long as the PSU is a quality unit and has the power you need thats all that matters. I believe that I did read somewhere for the GTX 480 a single rail PSU is recommended, but I see no reason to make the single or multiple rail config be the determining factor in a PSU.

    850 watts is a huge amount of power what are your system specs?

    The TPQ is a standard ATX unit and will fit most any case, it's the CP850 that follow's a different form factor and only fits certain Antec cases.

    I'd take the Corsair over the TPQ.
    650 watts would do unless you plan to Crossfire.

    I'm planning to crossfire to kepp it future proof.

    AMD 5870 requires only 600w and 4 6-pin pci-e power connectors for crossfire.
    http://www.amd.com/us/products/desktop/graphics/ati-radeon-hd-5000/hd-5870/Pages/ati-radeon-hd-5870-system-requirements.aspx

    I think 850w is a bit much when 750 or even 650 will do. An overspec'd psu will operate way below it's optimum efficiency.

    I suggest the XFX 750w unit:
    http://www.newegg.com/Product/Product.aspx?Item=N82E16817207003

    There is a lot to love:
    1) cheaper by $50
    2) modular
    3) silver certified efficient
    4) Very good reviews

    Also, single rail vs multi rail does not really mean much. There are marketing arguments for either. All quality units are safe.

    but wait you forgot, I have Hardrives ,Fans ,etc plug in too. so it equals around maybe 700 or 650w

    Everybody has fans, cpu,ram,dvd, a couple of hard drives etc. They do not amount to very much. The AMD recommendations include normal configurations, and are probably conservative to account for lesser quality psu's.

    Well its good to have some extra power (:
  11. I went with the TP750 NEW http://www.newegg.com/Product/Product.aspx?Item=N82E16817371025&cm_re=tp750-_-17-371-025-_-Product

    it got strangely high marks other than its "hybrid" modular design.

    Yes but i need 850w
  13. Are you sure you really need 850w? Try this PSU Calculator to see how much you will need: http://extreme.outervision.com/psucalculator.jsp

    Up to a point,you are correct. But... a PSU operates most efficiently in the middle third of it's range. An overly strong psu will not be as efficient as it can be.

    If you use the newegg one, i got around 800w for a crossfire , it looks like its really 700w but why not have extra just in case ?
