Quality PSU for new build - Over-spec?

Hi there good folks @ Toms,

I'm putting together a new build mainly for heavy video editing/FX, some 3D stuff [old software plus Max/Blender].

Have bought the case [Carbide Air 540, very happy there] and pretty happy with the spec so far, though I wonder is there a downside to too much overhead on PSU wattage.

Build as below, am going with the Z97 board for SLI option later on [no overclocking] hence the high wattage PSU. The Seasonic X reviews very well and quietness is a major issue. So is cooling. I'm playing a balancing act. [Heavy video rendering in Summer ambient temps 30C sometimes more needs the airflow]

Thoughts on the PSU wattage?

    Summary:

    Buy one. Do I really need to say anything else at this point? Once again, EVGA has something awesome here the competition can't seem to touch price wise. Performance? There are better units, yes. Not very many, but they exist. The real story here is how EVGA keeps managing to offer this kind of performance and still be more affordable than nearly everything else out there, and they have pretty much found perhaps the only OEM on Earth capable of doing it for them. It's got to be real nice being EVGA right now.

    The Good:

    outstanding ripple suppression
    excellent voltage regulation
    fully modular
    semi-fanless mode
    nice blacked out cabling

    The Bad:

    nothing at all

    The Mediocre:

    reviewing awesome units is getting dull... where's that gutless wonder in my pile? Second in line? Well, at least I'm guaranteed something interesting in all the wrong ways in a couple weeks...

    Value (20% of the final score) - $109.99 is the asking price of these at NCIX right about now. It shares this price with the Silverstone ST85F-GS. Now, about the only thing that unit has on this one is its much shallower depth. Other competition? What other competition? Coolmax? More money, if you can believe that. Corsair HX850? More money. Corsair RM850? More money. Themaltake Toughpower Grand? More money. Seasonic X-850 KM3? Way more money. EVGA has this category locked right down. 10.
  3. Thanks for your swift considered responses folks, very much appreciated.

    Good to know OK to drop to 850W - although as the power-calc says I should be looking at 760 min/810 recommended [583/633 single VGA card] will an 850 mean I'm running at the top end of the PSU capacity the whole time and thus increased heat/fan ?

    At this stage I'm still looking to go with the Seasonic as shown by rounakr94 - the noise levels of the EVGA are a fair bit higher and anything I can do to keep things down is all good. The price is awesome on the EVGA mind! But US only :(

    Pricing in AU means the two are a bit closer too and also the difference between the 850 and 1050 is only $20 - will the extra headroom be a problem having spare wattage for the $20?
  4. I think corsair ax860i should enough to your rig. And it's 7-years warranty
