More about overclock
  1. 650W is recommended if you want your PSU to keep long. FYI: Your CPU is unocked so just raise the multiplier by 0.5 until it is 4.0Ghz in BIOS.
  2. would 600w be enough?
  3. did you build this system? i seriously want to suggest getting rid of that psu in the build as it is known to fail fast. if you didnt build it yet, give me a budget range and i will build one for you

    the psu can handle it for now
  4. no i haven't built it yet, £670 is the max i can go:)

    Enough is enough, but if you want to make its life longer than get a better PSU. Get a better PSU also allows you to upgrade your specs anytime you want as you have sufficient power.

    £750 preferred, to get more detailed specs. :)
  7. i only want to play minecraft, tf2 and some other games in the future on max :P
  8. sorry that it is slightly over 670. 550w is more than enough for the system even when you overclock the CPU. the catch is that you cant add another video card. at full load at stock settings, you will probably pull under 250w with everything attached

    You are going to get the Arctic Cooling Freezer 13 CPU Cooler that means you have to throw the 14 x 2.5 cm top fan given by the casing?

    Agree, problems when adding another GPU.
  11. the video card can play bf3 at ultra with 50+ fps. easily capable of getting 100+ fps in TF2
  12. nice, i don't want to have two GPU's kelvin, troll i changed it around a bit and this is what im thinking,
    CIT 550W Gold 12Cm Silent Atx Power Supply

    Corsair CMZ8GX3M2A1600C9 8GB 1600MHz CL9 DDR3 Vengeance Memory Two Module Kit

    will the psu be enough?
  13. Enough, but please change the brand to prevent some power failures, just add some money. OK, for the casing, it says
    ■1 front mounted Fractal Design 140mm fan @ 1000rpm included
    ■1 rear mounted Fractal Design 120mm fan @ 1200rpm included
    ■1 top mounted Fractal Design 140mm fan @ 1000rpm included
    ■Additional 4 fan slots available for optional fans; one 120mm in front, one 120mm in bottom,one 120/140mm in top and one 120/140mm in side panel

    According to the information above, place the front, rear, top fans included to the place they give. Then, another optional 3 fans you wanted should be placed on the front, the bottom and the side. Your CF 13 should be placed on top. It will be 5 pushes (2 on front, 1 on bottom and 2 on top) and 2 pulls (1 on rear and 1 on side).

    Edit: If you can afford, take this PSU: http://www.corsair.com/builder-series-cx600-v2-80plus-certified-power-supply.html/ If cannot, get this (the performance will be lower): http://www.coolermaster.com/product.php?product_id=5888 Please change the topic title also if not the mods will treat this topic as a help needed on overclocking and they will move this topic to the overclocking section.
