How much power for this build?

Just a quick question on how much power I need for my first build.

Intel Core i5 4670k Quad Core LGA 1150 3.4GHz (overclocking to 4+ GHz)

Noctua NH-D14 CPU Cooler

MSI Z87-G45 GAMING LGA 1150 Motherboard

Samsung 840 EVO Series 120GB 2.5" SATA3 Solid State Drive

Seagate 3TB Barracuda 3.5” 7200RPM SATA3 Hard Drive - ST3000DM001

Gigabyte GeForce GTX 780 3GB Overclock Video Card

Corsair Vengeance 16GB (2x 8GB) DDR3 1600MHz Memory CMZ16GX3M2A1600C10

Zalman Z11 Plus High Performance Gaming Mid Tower Case (7 Fans total)

NZXT Sentry 2 5 25" Touch Screen LCD Fan Controller

Should I go with a 650w Gold Power Supply or a 700w Silver PSU?

Thanks

  1. Best answer
    For a single 780, a high end 600W power supply would be enough to power that system. What is your budget, and in what currency? Let's see if I can help find a good deal.

    Antec High Current Gamer 620W $54.99 (if you are in the U.S.)
    modular, 5 year warranty, made by Seasonic (arguably the best psu maker right now).

    Thanks for the quick answer but have you taken into account I'll be overclocking my CPU quite a bit as well? So I'll also be using an after market cooler. I also have 16GB of RAM and a total of 7 case fans with a LCD fan controller.

    I live in australia, and I was planning to get the Zalman 650w Gold PSU or the Zalman 700w Silver. They are both $130 AUD, which is also around my budget.
  3. Which model numbers are those PSUs you are looking at? Are they the ZM series? If so, they seem to be ok. Honestly though, I'm having a hard time finding reviews on the Zalmans. That doesn't necessarily mean they are bad. It's just for me personally, especially for a PSU I like to get one that has been thoroughly tested.

    This one is much cheaper than the Zalmans you are looking at, but has been tested and proven to be of extremely high quality. Made by Seasonic and both have won multiple awards from Hardware Secrets and JohnnyGuru (two of the top PSU testing websites).

    XFX Core Edition 650W $89

    and here is the modular version from XFX
    XFX XXX Edition 650W $99
    http://au.pcpartpicker.com/part/xfx-power-supply-p1650xxxb9

    These are both bronze rated, not silver or gold like the zalmans, but I would rather have good healthy power at lower efficiency than dirty power at a higher efficiency, if that makes sense.

    Again, I am not trying to steer you away from those Zalmans. Someone may come along and have some proof they are great. I just am saying what I would do.

    I might just go with your original Antec High Current Gamer 620W, but are you absolutely certain that it is enough power to handle a 4.5Ghz overclock?
  5. I use these sites to get rough estimates on how much Watts I'll need
