Whats a good 850w power supply for my build?

Hi,

what is a good psu that is 850w. It has to be gold or platinum, but to much money. My build is:

-Asus maximus vi hero
-intel i7 4770k
-Cool master haf X (maybe something cheaper)
- Evga geforce gtx780
-Asus 24x dvd burner
-Seagate barracuda 2tb
-G.Skill Ripjaws X 8gb

Should i go lower on my wattage or higher?

Thanks,

  1. First of all 850W is waaaay too much for your buid unless you're gonna add an extra GTX 780 with SLI.
    A 650W would be just fine with room for OC in the future, check this possibilities:

    Mid range price, mid range brand 80+ Gold = will do the job like a pro:

    Mid-high range price, High end brand 80+ Gold = Great for the money:

    Just the best, a bit expensive dho:

    In any case youll be just fine with each one of them so Enjoy!
  2. What about a 750w and would having too much power cause bad things?
  3. Having more room is always a good idea, for future upgrades, also the PSU would be working at midle load wich is the point where it gets better efficiency and lower-noise and ripple levels, so a 750W PSU for that rig would be just fine.
    Remember to pic good branded certified PSUs only, something like Seasonic, XFX, Corsair, Antec.

    Try to choose from Tier-1

    Tier-1 provides the best quality power, great for overclocking, super high-end systems, and bragging rights. The best of the best. Very good longevity.

    And not all PSU can handle HASWELL CPU, there are incompatibility issues.

    So you can go with this one, sufficient for your need, unless you want to OC or SLI.

  5. i did some calculators and most are suggesting 750w but i need more room for watercooling and maybe sli in the future so would a 850w still be ok? and what is tier-1?

    Also the powersupply has to be haswell certified
  6. Made by SEASONIC , and probably the best 850w. on the market at a great price.

    Scoring

    Performance (40% of the final score) - voltage stability? Excellent. Ripple suppression? Excellent. Pass for Gold efficiency both times. Units like this make scoring easy. 10.

    Functionality (20% of the final score) - this unit is more or less identical to big brother in this department, so it should come as no shock that I'm going to score it much the same way. I'd still like to see a SATA chain with some more length, and a few extra goodies in the box. I'll remove a half point for each of those issues again. But, there's more. I feel an extra CPU cable isn't a bad thing on an 850W unit. The modular board on the unit has the extra connector, so why not throw that in? Especially when the Seasonic G-650, a far smaller unit, came with one. Another half point off for that. But there I will stop, because this unit by far does a lot of things right more than wrong. It's fantastic. It just could have been even better, I think, in this category. 8.5.

    Value (20% of the final score) - this unit is currently going for $139.99 at Newegg. That's insane for a unit of this caliber! Know what the Seasonic equivalent is going for? Thirty bucks more money, and THAT price is still not a bad value. Folks, for the second week in a row, we've seen a unit that totally dominates its price bracket. Only the Corsair HX850 and XFX Pro Series Black 850W gives this thing any competition, and they're still ten dollars more money. Can't do anything but 10 here again.

    Build Quality (20% of the final score) - I found no issues whatsoever to complain about inside this unit, except for maybe the lack of any thermal grease on the 12V output heatsink where the two parts bolt together. Since this does not appear to be an issue for forty or even fifty degree operation at full power, this is a non issue. I smell another 10.

    tier1 is just a list with the best PSUs on the market , providing the best quality power, great for overclocking, super high-end systems, and bragging rights. The best of the best. Very good longevity.
    here is the full Eggxpert Tiered Power Supply List :
    Tier Breakdown:

    Tier 1 provides the best quality power, great for overclocking, super high-end systems, and bragging rights. The best of the best. Very good longevity.
    Tier 2 offers very good quality power output, and great reliability. Highly recommended for use in new systems.
    Tier 2b contains units that almost made Tier 2, but may not have quite as good quality output(still very good), or may not last as long. Recommended for systems not expected to run 24/7 for several years.
    Tier 3 power supplies fully meet all ATX requirements for power output quality, but don't have as good of power output quality as above tiers. No reason to replace one if you have one, and they're still good choices for most systems.
    Tier 4 units may have some problems, such as being unable to deliver rated power at higher temperatures, or being slightly out of ATX spec on power output quality. Not recommended to buy except in situations where you will not be stressing it, or expecting it to last for more than a few years. If you have one, you can probably keep using it unless you're experiencing problems.
    Tier 5 power supplies are NOT RECOMMENDED. If you have one, you should strongly consider replacing it ASAP. These can damage your computer, and often cannot put out the power that they're rated for. If a brand name is listed here, then all models from that brand name are considered to be Tier 5, except for those specific models listed above.

  8. Get the 850w I linked above, it's the best in it's class and the price is also.
  9. It needs to be haswell certiefed
  10. The 850w , I posted is Haswell Certified.

    http://coolermaster-usa.com/press_release/haswell/haswell.html
  11. But im not to sure with going with cool master for my powersupply i would rather seasonic or corsair
  12. It's made by SEASONIC not Coolermaster.
  13. umm no i dont think so sry its not one of the best
  14. Yes it is , but what you purchase is your choice.

    I only offer advice.

    Any calculators showing you need 750 for a sys with 1 780 are building in way more headroom than you need.
    A good quality 550 will run that system. There's no problem using a 750 except to your wallet in upfront cost.

    If you are convinced you want an 850, the CM V850 blackbird linked is an excellent unit. The 3 V series CM PSU's
    all made by Seasonic are ex quality.
  20. I AGREE 100% FROM MY PERSONAL EXPIRIENCE THE COOLERMASTER V850 IS INCREDIBLE AND YES IT IS MANUFACTURED BY SEASONIC.
