Is XFX ProSeries 450W enough for me?

http://xfxforce.com/en-gb/Products/Power-Supply/XFX/Pro-Series/ProSeries-450W-PSU.aspx

Is this power supply enough for all these components:
XFX HD7850 1GB GDDR5 - http://xfxforce.com/en-gb/Products/Graphics-Cards/AMD/AMD-Radeon-HD-7000/AMD-Radeon-HD-7850.aspx
KINGSTON V300 120GB SSD - 450/450Mb/s 2.5" SATA3 http://www.kingston.com/datasheets/sv300s3_us.pdf
AMD Phenom II X4 965 Black Edition - http://www.cpu-world.com/CPUs/K10/AMD-Phenom%20II%20X4%20965%20Black%20Edition%20-%20HDZ965FBK4DGM%20(HDZ965FBGMBOX).html
AsRock 970DE3/U3S3 - http://www.asrock.com/mb/AMD/970DE3U3S3/
KINGSTON HyperX RAMkit 8GB 2x4GB 1333MHz - http://www.kingston.com/us/memory/hyperx/blu/black
Also will be using one 7200 rpm hdd and dvd-cd combo drive and usb mouse and sometimes using usb memory sticks and etc.
Also atleast 1x140mm fan and 120mm fan

I already used OuterZone free psu calc and it gave me an result of recommended 396w psu without overclocking and without capacitor aging and with 100% load.
With overclocking on and capacitor aging 20% and 90% load it gave me an result of minium 419w psu and recommended psu wattage of 463w.

Newegg calc said I need 440w psu. Am I good to go with this setup?
I wont probably be doing alot of overclocking, but I'd like there to be just a little space for overclocking. I used 1.5v and 3.8Ghz settings for overclocking in the OuterZone psu calc.

    Yes - it will run that setup - but if you haven't already purch your psu

    consider XFX 550w that nets to $40 after prom & mir (if you are in the US)

  2. You'll be fine. You'd only need more than 450W if your usin' something like a 5970 at full fettle.
  3. yeah thats a fine purchase the xfx 450, but if u want a bit more juice and more upgrade paths, get the one toyfw recommanded +-+
  4. allright, thank u guys alot for the quick responses. now i feel safe to purchase these components :)
  5. cheers my friend, feel free to msg me private if u need more help.
  6. For a system using a single reference clocked Radeon HD 7850 graphics card AMD specifies a minimum of a 500 Watt or greater power supply. The power supply should also have a combined +12 Volt continuous current rating of 27 Amps or greater and have at least one 6-pin PCI Express supplementary power connector.

    Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Sufficient Total Combined Continuous Power/Current Available on the +12V Rail(s) rated at 45°C - 50°C ambient temperature, is the most critical factor.

    You may find power supplies on the market that supply more than enough Wattage to run the system. However, some of them lack Sufficient Amperage capacity on the critical +12 Volt rail, which is necessary to properly power the critical components in the system (i.e. CPU and GPUs). This is the reason why graphics card manufacturers overstate the power supply wattage, usually by at least 50 Watts, to take into account those power supplies that have the weaker +12 Volt rail(s).

    The XFX 450W Core Edition Full Wired (Bronze) (P1-450S-U2B9), with its combined +12 Volt continuous current rating of 34 Amps and with one (6+2)-pin PCI Express supplementary power connectors, is more than sufficient to power your system configuration with a single Radeon HD 7850.

    There's even some spare capacity available for overclocking.
