What PSU should i get (or how many watts) for this build:

CPU - intel core i5 3570k
CPU cooler - thermaltake water 2.0 extreme
Graphics card - EVGA GeForce GTX 670 SuperClocked+ w/Backplate 4g
RAM - Corsair Vengeance 8g
SSD - SAMSUNG 830 Series 128g SATA III
HDD - Seagate Barracuda 3T

More about which pick
  1. Please it needs to be modular.

  2. minimum requirement is 500W but more room wattage is good too 520 - 600 ,
    SeaSonic S12II 52W same price with CORSAIR Builder Series CX600
    Antec BP550 Plus 550W ATX12V V2.3 Modular Power Supply ( modular)
    i think ran single gpu not fully modular is ok
  3. the specs u have mentioned, (excluding : Optical Drives, Additional PCI Express Cards, case fans, flex lights, External Devices,Cold Cathodes....Other Devices) will consume ~600W... recommended psu: cooler master GX-650W or 600w OCZ ModXstream or Corsair Enthusiast Series 650-Watt TX650..

    Get this or this (much better option, but only if you can afford it) and you're pretty much good to go.
    Whatever you do, DO NOT get any of the Corsair's "CX" line, it's absolute crap.

    I also highly recommend that you read this, before you make the final decision.
  5. Thanx for the advice guys! :)
    But will the amount of W I need significantly increase if i add an optical drive, fans, and lights?

    Not by much. Anyway, go here or here, and just input the desired hardware, to get the approximate numbers.

    yes it does increases, but "NOT THAT SIGNIFICANTLY"....
    u can not count optical drives, other pci cards, lights etc etc as PETTY THINGS. . . . They do matter :)
  8. Fan are about 3-8W each max. An Optical drive is rated around 25W max. To calculate W draw from lights you multiply the amperage rating by 12V. Overall you will find that these items do not add a relatively large load to the system; when selecting a PSU the primary load concerns are the CPU/GPU. After that I would think about ODD/HDD as they can be decent sized power draws if a lot of them cycle up at the same time...but that doesn't happen a lot. If you had a Raid 5 with 4-6drives in it then I would factor that somewhat higher thana JBOD because the array will spin up at the same time.
  9. I would get


    I say 750 or 850 in case you plan to SLI later. I Went with a 1200 corsair cuz I like overkill but I knew I would want to sli and sure enough I did. I have a 2nd coming tomorrow. Future proof this build with a higher watt psu now so you dont have to buy another later when you want to sli.

    The PSU Wattage we recommend only gives you a general idea on what to consider while selecting a power supply. PCI cards, External devices, USB and Firewire devices, Cooling fans and other components may need more power.

    The recommended total Power Supply Wattage gives you a general idea on what to look for BUT it is NOT a crucial factor in power supply selection! Total Amperage Available on the +12V Rail(s) is the most important, followed by the +5V amperage and then the +3.3V amperage.
