now i plan to overclock the gpu as high as i possibly can, which from reading about the gpu is about 1ghz, as well as overclock the cpu to about 3.6, if i can maybe higher

will the 520 watt psu be enough?

  1. at stock the Seasonic 520w will handle it but with all that OC, i would grab the 620w version just for the added head room. Antec also sells a single rail 520/620w PSU made by seasonic. I think its $5-10 if money is an issue.
  2. i can get a 620w from seasonic thats also modular for about 10$ more

    just a q, how bad is cable management with a psu that isnt modular?

    depends on the the person who installs the PSU :na:

    modular is nice but far from a necessity and if your case has cable management holes then it makes it even easier.
  4. i would say definitely go for the 620w version-modularity is just a plus :)

    Also depends on the case. I have Antec 900 cases. I drill a few extra holes in the bottom of the case under the lower drive cage and tie the unused cables down.
  6. well ill be using a haf922 so im guessing theres good cable management
  7. The HAF is a good choice.
  8. ok now will a 620w psu handle a second directCu also overclocked, or will i need a bigger psu?
