PSU question. First time build. 550w enough?

Hey guys im making my first desktop and i had a question about what power supply i would need for my build. im currently looking at getting the Antec BP550 Plus 550W PSU for $65 off newegg.

My build is:

i7-2600k (will probably overclock to 4.3 ghz)
MSI R7850 Twin Frozr (may overclock this a tad too)
ASRock Z77 Pro4
ADATA S510 120gb SSD
Kingston HyperX T1 Series 8GB (2 x 4GB) DDR3 1600 RAM
COOLER MASTER Hyper 212 Plus CPU cooler
Rosewill CHALLENGER-U3 + 1 COOLER MASTER SickleFlow green
ASUS DRW


The question is is 550w enough to run this? What PSU would you recommend. Also any other suggestions to the build welcome too :)

Thanks

  2. prototype has some good suggestions for the PSU. for not much extra money you are getting a noticeable jump in quality and features.

    What are you using your PC for? if it's for gaming and you don't do any major video or photo processing then I'd recommend dropping down to an i5 3570k, which is still plenty for gaming, and everything else too! you could then spend that savings on a better graphics card. An i7 is really only necessary if you are going to be doing media editing or using winrar all day.

    I've not had first hand experience with this case but I think it will be worth the $5 extra to get this case:

    i was planning on using the desktop mainly to play and sometimes stream sc2 which is more cpu intensive then gpu intensive. I got the case because a friend has it and he likes it + USB 3.0, i think everything should fit well. I might end up getting the 620W one just in case i need a bit more then 550.
  4. 550 watt is plenty for your rig and my selection would be between these two just based on price and quality http://www.newegg.com/Product/Productcompare.aspx?Submit=ENE&N=100007657%20600014021%20600014072&IsNodeId=1&bop=And&CompareItemList=58%7C17-207-013%5E17-207-013-TS%2C17-341-047%5E17-341-047-TS recently bought the OCZ when it had a better incentive and none of the issues stated in the bad reviews, works flawlessly and is quiet.
  5. all these psu's seem to be non modular though, i think my case is too tiny for being non modular.
  6. Modular tend to be expensive. That Antec you link to is the least expensive modular currently on Newegg. The Seasonic M12II was on sale for even less and is great, but unfortunately out-of-stock. I'd watch the next couple of days and see if it becomes available again.
  7. Nice modular option cheap if you count in MIR and gift card PC P&C 600watt http://www.newegg.com/Product/Product.aspx?Item=N82E16817703036

    U surely dont need a modular PSU. Not worth the extra money. But jwk3 is right (Haf 912 its way better than that case so if u didnt bought the rosewill go get the HAF 912)

    Xfx 550 or Corsair ( worth the 5$ extra)
